Hemoglobin electrophoresis is a well-established technique routinely used in clinical laboratories to screen samples for hemoglobinopathies (hemoglobin variants and thalassemias).. May also include abnormal ranges. The range for a normal hemoglobin level may differ from one medical practice to another. HbC is an abnormal form of hemoglobin associated with hemolytic anemia. In adults, the percentages of certain hemoglobin molecules should be: Hemoglobin Molecules . Application: Possible Thalassaemia or Haemoglobinopathy, including those haemoglobinopathies associated with DAT negative haemolysis, erythrocytosis, or … The kit is used with the automated . You may have this test if your health care provider suspects that you have a disorder caused by abnormal forms of hemoglobin (hemoglobinopathy). Levels of Hb A 2 in the low to low normal range (1.5–2.5%) and β/α synthetic ratios averaging 1.4 : 1 characterize α°-thalassemia trait. Links to other sites are provided for information only -- they do not constitute endorsements of those other sites. Some labs use different measurements or may test different samples. HbA 2 … Hemoglobin electrophoresis is a blood test commonly used to diagnose and characterize disorders of hemoglobin, called hemoglobinopathies. However, hemoglobin electrophoresis is only one of several tests that can detect and characterize abnormal hemoglobins. Mosby's Manual of Diagnostic and Laboratory Tests, 4th ed. Many different types of hemoglobin (Hb) exist. Some people may also have small amounts of HbF. A hemoglobin electrophoresis will indicate if there are any abnormal types of hemoglobin caused by genetic disorders. Hemoglobin electrophoresis in acid agar would show this abnormal hemoglobin migrating as Hb A. You may get a small bruise at the site. The symptoms are much milder than they are in sickle cell anemia. E. Gregory Thompson MD - Internal Medicine, Latest Vaccine Availability and Distribution Information, Medical Tests: Questions to Ask the Doctor, © Copyright 1995-2021 Regents of the University of Michigan, Find each type of hemoglobin in the blood. The health professional drawing blood will: The blood sample is taken from a vein in your arm. Philadelphia, PA: Elsevier Saunders; 2016:chap 158. If the MCV and MCH are not low, the case can be signed out as normal hemoglobin electrophoresis. In Hb CS trait, red blood cell (RBC) parameters are within the normal range, and screening is impossible using RBC indices alone. Your use of this information means that you agree to the Terms of Use. Electrophoresis and high-performance liquid chromatography as well as molecular genetics testing for mutations can also be used to identify abnormal forms of Hgb. This means that a value that falls outside the normal values listed here may still be normal for you or your lab. Furthermore, Hb Melusine yielded normal HPLC and capillary electrophoresis of Hb program profiles, and only yielded an unusual peak through capillary electrophoresis of the HbA1c program 10. Pagana KD, Pagana TJ (2010). Newborns are also routinely screened for these genetic hemoglobin disorders. May also include abnormal ranges. When hemoglobin electrophoresis reveals a normal pattern, i.e., HbF is <1%, HbA2 is <3.5% and the remainder is HbA, check the CBC values. Reference Interval Normal range/expected value(s) for a specific disease state. Hemoglobinis a protein that carries oxygen in the blood. The amount of hemoglobin in your bloodstream is measured through complete blood count. The hemoglobins move on the paper and form bands that show the amount of each type of hemoglobin. If you're a patient or visitor in one of our hospitals or clinics, you are required to wear a mask. Anemia (also spelled anaemia) is a decrease in the total amount of red blood cells (RBCs) or hemoglobin in the blood, or a lowered ability of the blood to carry oxygen. Most pharmacists will be familiar with the “pin-prick” used to obtain a few drops of blood from a finger tip or earlobe to measure blood-glucose levels. Often, if an abnormal result is obtained with the electrophoresis test, sophisticated testing can be … Hemoglobin types have different electrical charges and move at different speeds. Test presentation . Having a blood transfusion in the past 3 months. Hb C. 0%. In some patients with a plasma cell dyscrasia, serum protein electrophoresis may be normal because the complete monoclonal immunoglobulin is absent … For both ranges, the measured HbA 2 values were also within the 95% confidence interval of the target value. Hemoglobin electrophoresis is a test that measures the different types of the oxygen-carrying protein (hemoglobin) in the blood. Looks like you’re visiting UCSF Health on Internet Explorer. The normal values listed here—called a reference range—are just a guide. Hb F. 0.8% to 2%. A hemoglobin electrophoresis test applies an electric current to a blood sample. There is very little chance of a problem from having a blood sample taken from a vein. Normal Results. Chernecky CC, Berger BJ (2008). Her serum hepcidin levels were above the normal range (5.63 nM; normal range, 3-7 nM). When the needle is inserted to draw blood, some people feel moderate pain. Current as of: UCSF Benioff Children's Hospital – Oakland, UCSF Benioff Children's Hospital – San Francisco. There is very little risk involved with having your blood taken. Heterozygous Hemoglobin S 1. Remove the band from your arm when enough blood is collected. Hb A. Hemoglobin fractions are directly detected at an absorbance of 415 nm. Other names: Hb electrophoresis, hemoglobin evaluation, hemoglobinopathy evaluation, hemoglobin fractionation, Hb ELP, sickle cell screen For hemoglobin elution peaks with retention times <0.63 min, the proportion of total hemoglobin (%Hb) was determined by densitometry of the alkaline electrophoresis gel using the QuickScan 2000 (Helena Laboratories) and/or manual calculation. Performances. Some kids might feel faint or lightheaded from the test. The HbA2 level for HbE heterozygotes was 3.58% (SD 0.44%), which was significantly higher than normal (p < 0.001) but lower than that of beta-thalassaemia heterozygotes (p < 0.001) and … Check treatment for diseases that have abnormal types of hemoglobin in the blood. 25th ed. HbA2, composing of two α chains and two δ chains, is a minor component of the hemoglobin present in normal adult red blood cells, accounting for about 2.5% of the total hemoglobin in healthy individuals. Thalassemias are a group of hemoglobinopathies caused by genetic mutations of hemoglobin genes, resulting in reduced production or total absence of 1 or more globin chains. Put a gauze pad or cotton ball over the needle site as the needle is removed. Manual calculation was accomplished by determining the peak area of each elution peak, i.e., the product of the height and the width at half … The hemoglobin electrophoresis test measures the percentage of the various types of hemoglobin in your bloodstream. ObjectivesBlood from the umbilical cord (cord blood) is screened for haemoglobinopathies in several neonatal screening programmes, as well as before banking as a source of stem cells. Hemoglobin electrophoresis is a blood test to measure the levels of the different types of hemoglobin potein in the blood. It is worth noting that infants and adults have different normal levels of hemoglobin. Put the needle into the vein. Taking blood from some people may be more difficult than from others. The most common ones are HbA, HbA2, HbE, HbF, HbS, HbC, HbH, and HbM. In adults, these are normal percentages of different hemoglobin molecules: HbA: 95% to 98% (0.95 to 0.98) For men the haemoglobin reference range is between 130 – 180 g/L and females 120 – 160 g/L. Each type of hemoglobin can then be measured individually. The electrophoretic test is performed at alkaline pH and provides a valuable screening method for Hemoglobin patterns. © 1995-2021 Healthwise, Incorporated. In summary, a normal capillary electropherogram by HbA1c or Hb program or chromatogram by ion‐exchange HPLC cannot exclude the presence of an Hb variant. No special preparation is necessary for this test. Laboratory Tests and Diagnostic Procedures, 5th ed. In Hb CS trait, red blood cell (RBC) parameters are within the normal range, and screening is impossible using RBC indices alone. When anemia comes on slowly, the symptoms are often vague and may include feeling tired, weakness, shortness of breath, and a poor ability to exercise. September 23, 2020, Author: Healthwise Staff Medical Review: E. Gregory Thompson MD - Internal Medicine Adam Husney MD - Family Medicine Martin J. Gabica MD - Family Medicine, Medical Review:E. Gregory Thompson MD - Internal Medicine & Adam Husney MD - Family Medicine & Martin J. Gabica MD - Family Medicine. Hemoglobin (Hgb) electrophoresis is a separation process used to identify normal and abnormal forms of Hgb. 13 Dr. Jasleen Kukreja and the Life-Saving Gift of Breath, Care, Convenience and Support at New Cancer Facility, 10 Ways to Get the Most Out of Your Doctor’s Visit, UCSF Health Ranked Among Nation's Top 10 Hospitals, Inherited blood disorder in which the body makes an abnormal form of hemoglobin (, Infection (a slight risk any time the skin is broken). Hemolysate is prepared from blood in EDTA, or citrate, or heparin. Many different types of hemoglobin (Hb) exist. Help couples find out how likely they are to have a child with certain forms of anemia that can be passed from a parent to a child (inherited). Plasma or serum in someone who does not have hemolytic anemia may contain up to 5 milligrams per deciliter (mg/dL) or 0.05 grams per liter (g/L) hemoglobin. Attach a tube to the needle to fill it with blood. In: Goljan EF, ed. Copyright ©2019 A.D.A.M., Inc., as modified by University of California San Francisco. Also, your doctor will evaluate your results based on your health and other factors. To learn more about Healthwise, visit Healthwise.org. Other risks associated with having blood drawn are slight but may include: Bunn HF. As a result, other screening methods are required. The hemoglobin molecules will have different percentages in infants and children … A large band of Hb A and a small band of Hb H are seen. Alpha-1 globulin: 0.1 to 0.3 g/dL or 1 to 3 g/L. Call 911 for all medical emergencies. Normal hemoglobin carries and delivers oxygen well, but some abnormal types of hemoglobin do not. Please discuss with your doctor any questions or concerns you may have. The most common ones are HbA, HbA2, HbE, HbF, HbS, HbC, HbH, and HbM. Above-normal haemoglobin levels may be the result of: dehydration; excess production of red blood cells in the bone marrow; severe lung disease, or This soon goes away. Hb A2. The history and findings are typical of Hb H disease, usually due to the inheritance of a total of three deleted alpha chain genes. A hemoglobin electrophoresis test is a blood test done to check the different types of hemoglobin in the blood. The normal range for hemoglobin is: For men, 13.5 to 17.5 grams per deciliter; For women, 12.0 to 15.5 grams per deciliter; Normal ranges for children vary with age and sex. Age-Defined Normal Hemoglobin Reference Intervals; Age Hb A Percent Hb A 2 Percent Hb F Percent Hb S Percent Hb C Percent ... Hemoglobin, Capillary Electrophoresis: 13514-5 Approach to the anemias. In the lab, the technician places the blood sample on special paper and applies an electric current. Tell your doctor if you are getting iron therapy for iron deficiency anemia. A hemoglobin electrophoresis test measures the different types of hemoglobin in the blood. If the hemoglobin electrophoresis pattern is normal but the MCV and MCH are low, with or without anemia, we need to check the iron profile. Philadelphia: Lippincott Williams and Wilkins. You can lower the chance of bruising by keeping pressure on the site for several minutes. In a recent study, 100% of patients with known Hb CS trait were detected using CE system, while 76.2% (16 … Normal values in an adult male are approximately 135 to 175 grams per litre, and an adult female, 115 to 165 grams per litre of blood but are influenced by the age, sex and ethnic origin of the person. Normal. The hemoglobin electrophoresis test is a blood test that can detect normal and abnormal hemoglobins, and begin to characterize the type of hemoglobinopathy if any exists. 2% to 3%. Lower than normal results. For other blood tests, blood is usually drawn from the median vein in the antecubital fossa (area in front of the elbow), after applying a tourniquet to the upper […] For a normal range of HbA 2 (target value, 2.7%), the sample was run 8 times a day on 9 days during a 1-month period. Do not freeze and thaw the Control more than 15 times. Beta globulin: 0.7 to 1.2 g/dL or 7 to 12 g/L. In HbS/β0-thalassemia, there is no HbA. The 2 major types of protein present in the serum are albumin and the globulin proteins. 96.5%–98.5% of total hemoglobin or 0.96–0.985 mass fraction, 1.5%–3.5% of total hemoglobin or 0.015–0.035 mass fraction, 0%–1% of total hemoglobin or 0–0.01 mass fraction. This is the main type of hemoglobin in an unborn baby's body. Healthy adults only have significant levels of only HbA and HbA2. Normal value ranges are: Total protein: 6.4 to 8.3 grams per deciliter (g/dL) or 64 to 83 grams per liter (g/L) Albumin: 3.5 to 5.0 g/dL or 35 to 50 g/L. You may feel nothing at all from the needle, or you may feel a quick sting or pinch. Electrophoresis uses an electrical current to separate normal and abnormal types of hemoglobin in the blood. Reference Interval Normal range/expected value(s) for a specific disease state. Higher-than-normal amounts of both hemoglobin A2 and, Hemoglobin S in moderate amounts can mean that, Hemoglobin C in low amounts can mean that. Results: The normal ranges for HbA2 and HbF by CE were 2.75% (SD 0.26%) and 0.03% (SD 0.24%) respectively, which were significantly lower than that of HPLC 2.88% (SD 0.25%) and 0.58% (SD 0.61%) (p < 0.001). In a recent study, 100% of patients with known Hb CS trait were detected using CE system, while 76.2% (16 out of 21) were detected using HPLC. Information developed by A.D.A.M., Inc. regarding tests and test results may not directly correspond with information provided by UCSF Health. Other, less common, abnormal Hb molecules cause other types of anemia. It has been recommended that all individuals of all ethnic groups except Northern European Caucasians be screened for variant hemoglobins, all ethnic groups for β-thalassemia trait, and selected ethnic groups for α-thalassemia trait (1). The most common types of normal hemoglobin are: There are more than 350 types of abnormal hemoglobin.footnote 1 The most common are: Hemoglobin S and hemoglobin C are the most common types of abnormal hemoglobin that may be found by an electrophoresis test. St. Louis: Mosby Elsevier. Fischbach FT, Dunning MB III, eds. Hemoglobin types S and C mean hemoglobin S-C disease, which causes a mild or moderate form of sickle cell disease. The increase in hemoglobin A2 (HbA2) level is the most significant parameter in the identification of β-thalassemia carriers. Doctors may order the test to help diagnose conditions related to irregular hemoglobin production, such as sickle cell disease or thalassemia. In people with this condition, the red blood cells sometimes have a crescent or sickle shape. For example, hemoglobin S is found in sickle cell disease, which is a serious abnormality of the blood and causes serious problems. This can help you and your partner see how likely you are to have children with certain inherited forms of anemia (such as sickle cell disease or thalassemia). Hemoglobin electrophoresis is a well-established technique routinely used in clinical laboratories to screen samples for hemoglobinopathies (hemoglobin variants and thalassemias). Thalassemia and thalassemic hemoglobinopathies pose serious health problem leading to severe morbidity and mortality in Indian population. In adults, these are normal percentages of different hemoglobin molecules: In infants and children, these are normal percentage of HbF molecules: Normal value ranges may vary slightly among different laboratories. Healthy hemoglobin can carry and release oxygen in an efficient way, while abnormal molecular forms fail to do so. Every unborn baby produces a minor adult type haemoglobin called Hemoglobin A2; this haemoglobin is produced irrespective of the type of major adult haemoglobin they have inherited from their parents. Hemoglobin electrophoresis measures the levels of the different types of this protein in the blood. An elastic band is wrapped around your upper arm. Diagnosis : Hb Lepore Hb Lepore has an abnormal "beta" chain made up of the beginning of the delta chain and the end of the beta chain. • In HbS/β +-thalassemia, Hb A is approximately 5%–15% with no history of RBC transfusion. Objective: The capillary electrophoresis (CE) is a new system that utilizes the principle of electrokinetic separation of molecules in eight electrolyte buffer-fi lled silica capillaries. Haemoglobin levels are different in adult females and males. Normal hemoglobin carries and delivers oxygen well, but some abnormal types of hemoglobin do not. In rare cases, the vein may become swollen after the blood sample is taken. St. Louis: Saunders. The CV was between 1.4% and 3.0%. ... these are normal percentages of different hemoglobin molecules: HbA: 95% to 98% (0.95 to 0.98) HbA2: 2% to 3% (0.02 to 0.03) HbE: Absent; HbF: 0.8% to 2% (0.008 to 0.02) HbS: Absent; HbC: Absent; In infants and children, these are normal percentage of HbF molecules: HbF (newborn): 50% to … Lower limit of normal range Hb (g/L) 2 months: 90: 2 – 6 months: 95: 6 – 24 months: 105: 2 – 11 years: 115 >12 years : female – 120 male - 130: Assessment History. Goljan EF. During the perinatal period, elevated amounts of Hb Bart are noted (3–8%). Interpretation of hemoglobin electrophoresis requires knowledge of previous transfusions, age of patient, CBC and peripheral blood smear results. 1. Healthwise, Healthwise for every health decision, and the Healthwise logo are trademarks of Healthwise, Incorporated. This protein comes in different molecular forms, some of which are normal and some are abnormal. Albumin is the major protein component of serum and represents the largest peak that lies closest to the positive electrode. Philadelphia, PA: Elsevier Saunders; 2014:chap 12. Diagnosis of Thalassemias . Objective: The capillary electrophoresis (CE) is a new system that utilizes the principle of electrokinetic separation of molecules in eight electrolyte buffer-filled silica capillaries. Some labs use different measurements or may test different samples. This makes the veins below the band larger so it is easier to put a needle into the vein. Normal Results. ... A hemoglobin electrophoresis test is a safe procedure with minimal risks. Certain diseases are associated with high HbF levels (when HbF is more than 2% of the total hemoglobin). Hemoglobin is a protein inside your red blood cells and helps carry oxygen and supply it to the cells. 4th ed. Reasons you may not be able to have the test or why the results may not be helpful include: If you are planning to have children and are found to have abnormal types of hemoglobin in your blood, you might consider genetic counseling. Results are ready in several days. Normal Results. A hemoglobin electrophoresis test applies an electric current to a blood sample. This arises from a cross over between the two chromosomes 11 as shown in the diagram. More than one needle stick may be needed. The Hemoglobin Electrophoresis test is used to detect and quantify both normal and abnormal forms of Hemoglobin.Hemoglobin is a protein in red blood cells which helps transport oxygen. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Hemoglobin electrophoresis will demonstrate Hb S, Hb F, and Hb A2 (>3.5%). In laboratory testing to confirm a diagnosis of a β-thalassemia trait diagnosis, Hb A2 levels should be considered in conjunction with family history and additional laboratory data, including serum iron and iron binding capacity, red cell morphology, hemoglobin, hematocrit, and mean corpuscular volume (MCV). Wrap an elastic band around your upper arm to stop the flow of blood. The CAPILLARYS Hb A1c assay is based on the principle of capillary electrophoresis in free solution. Manual of Laboratory and Diagnostic Tests, 8th ed. Hgb A is the main form of Hgb in the normal adult. The normal values listed here—called a reference range—are just a guide. IMPORTANT: After storage at 2 - 8 °C or between - 18 °C and - 22 °C, homogenize the reconstituted Normal Hb A2 Control before the analysis. Persons with beta thalassemia major require periodic and lifelong blood transfusions to maintain a hemoglobin level higher than 9.5 g per dL (95 g per … The hemolysed Normal Hb A2 Control should be stored at 2 - … Hemoglobin (Hb) A is the most abundant hemoglobin (>95%) in healthy adults and is formed by 2 α chains and 2 β chains.1 Hemoglobinopathies include structural and quantitative changes in hemoglobin chains. A warm compress can be used several times a day to treat this. The symptoms are much milder than they are in sickle cell anemia. The identity of a hemoglobin variant is generally inferred from i… Reference Range. The aim of the present study was to analyze laboratory aspects, namely, hematological profile and HPLC findings of the hemoglobin variants detected, and to discuss problems that we faced in diagnosis in a routine clinical laboratory.
