HB Electrophoresis Test in Pregnancy

It’s crucial to keep an eye on a woman’s health during her pregnancy to safeguard her well-being as well as the health of the developing child. HB Electrophoresis is a vital test that is frequently advised since it evaluates the existence of aberrant hemoglobin variations in the blood. An in-depth analysis of the significance of HB Electrophoresis in pregnancy, a discussion of normal hemoglobin levels, an explanation of the test’s methodology, and an estimate of its cost are all included in this blog post.

HB Electrophoresis Test: Why is it Done?

To detect aberrant hemoglobin variations, specifically hemoglobinopathies such as sickle cell disease and thalassemia, the HB Electrophoresis Test is carried out during pregnancy. Haemoglobin, the protein that carries oxygen in the blood, has changed in its composition or production in certain diseases. It is essential to identify these hemoglobinopathies in order to manage and care for the pregnant woman properly.

Detection of Hemoglobinopathies

Hemoglobinopathies can be discovered by HB electrophoresis, which identifies carriers of defective hemoglobin variations. If a woman is discovered to be a carrier, additional testing on the father may be required to determine the likelihood that the child may inherit a hemoglobinopathy.

Prevention and Management

Early detection of hemoglobinopathies during pregnancy enables medical professionals to provide appropriate counseling and management. They can use it to design a care strategy that emphasizes preventing complications and offering suitable treatment alternatives.

Genetic counseling

The findings of the HB Electrophoresis test can assist couples in understanding the possibility of transferring hemoglobinopathies to their progeny. It enables educated decision-making, including choices for prenatal genetic testing and family planning.

Normal Hemoglobin Levels

Hemoglobin levels that are considered normal might change depending on a person’s age, gender, and health. The usual range for hemoglobin levels during pregnancy is between 11.0 and 13.5 grams per deciliter (g/dL). It is crucial to remember that these values may somewhat vary between laboratories and healthcare organizations.

What Do Abnormal Levels Of Hb Electrophoresis Test In Pregnancy Indicate

When performed during pregnancy, the HB Electrophoresis Test can reveal the presence of aberrant hemoglobin variations called hemoglobinopathies. The following are some consequences of unusual results:

Sickle Cell Disease

High levels of aberrant hemoglobin S (HbS) could be a sign of sickle cell disease. Red blood cells with this genetic disease develop crescent shapes, which limit oxygen delivery, harm organs, and increase the risk of pregnancy difficulties.


A set of genetic blood illnesses that disrupt the generation of normal hemoglobin might be indicated by abnormal levels of hemoglobin A2 (HbA2) or hemoglobin F (HbF). Thalassemia can cause anemia, organ damage, and pregnancy difficulties.

Hemoglobin Variants

It’s possible to find abnormal hemoglobin variants like hemoglobin C (HbC) or hemoglobin E (HbE). These variations may need to be further examined to determine their possible consequences on pregnancy as they may affect the blood’s ability to carry oxygen.

It is crucial to remember that abnormal HB Electrophoresis test findings should be interpreted and discussed by a medical professional with experience in hematology and prenatal care. To guarantee the best outcomes for the mother and the child, they will offer advice, suggest more testing if necessary, and suggest suitable management techniques.

HB Electrophoresis Test Procedure 

  • For the most part, the HB Electrophoresis test doesn’t require any special preparation. Following any recommendations given by your healthcare provider is always advised, though.
  • A blood sample will be taken by a qualified healthcare expert, usually from an arm vein. After applying an antibiotic to disinfect the area, blood will be drawn using a sterile needle and syringe. After that, the sample is put into a test tube.
  • The blood sample is delivered to a lab for examination. The electrophoresis procedure, which divides various types of hemoglobin based on their electrical charge, will be carried out by skilled professionals. This makes it possible to recognize and measure the different hemoglobin variations that are present in the blood.
  • Your results will be given to you by the laboratory after the analysis is finished. Your doctor will explain the results to you in detail and interpret them. 
  • A doctor may advise additional testing or consultations if any aberrant hemoglobin variations are found.

HB Electrophoresis Test Cost 

The location, healthcare institution, and any extra tests or services involved can all affect the price of the HB Electrophoresis test. The usual cost of HB Electrophoresis in Delhi is between INR 800 and INR 2000, or even more. It is important to keep in mind, nevertheless, that costs can vary between laboratories and healthcare organizations. To get precise and current information about the price of HB Electrophoresis testing during pregnancy, it is advisable to get in touch with particular medical facilities or laboratories.


In particular, HB Electrophoresis testing is crucial for spotting aberrant hemoglobin variations that could be dangerous for both the mother and the unborn child. It aids in hemoglobinopathies’ detection, enabling appropriate care, prevention, and genetic counseling. Expectant women can use the knowledge of normal hemoglobin levels and the steps involved in HB Electrophoresis testing to help them throughout their prenatal journey. It is crucial to seek the advice of skilled medical professionals for the interpretation of test findings and for individualized support during your pregnancy.
