Anaemia test in pregnancy in Delhi | Anaemia test in pregnancy in India | G6PD Test in Delhi
Anaemia during pregnancy is a common health concern that deserves timely investigation and appropriate medical care. The World Health Organization (WHO) defines anaemia in pregnancy as haemoglobin (Hb) below 11 g/dL in the first and third trimesters and below 10.5 g/dL in the second trimester. As the body supports the growing baby, iron requirements increase, and deficiencies of essential nutrients may affect haemoglobin production. Although mild tiredness can occur during pregnancy, persistent fatigue, dizziness, breathlessness or paleness may indicate anaemia.
At Dr. Dangs Lab, diagnostic testing helps doctors evaluate haemoglobin levels, identify potential nutritional deficiencies and investigate other causes of anaemia, including inherited blood disorders and red blood cell enzyme deficiencies such as G6PD deficiency. The right blood tests, interpreted alongside pregnancy stage and clinical history, can support appropriate treatment and follow-up.
Why Is Anaemia Testing Important During Pregnancy?
During pregnancy, plasma volume increases more than red blood cell mass, causing physiological haemodilution. However, a low haemoglobin level may also result from iron deficiency, folate deficiency, vitamin B12 deficiency or an underlying blood disorder. In some cases, anaemia may develop because red blood cells are destroyed faster than the body can replace them, a process known as haemolysis.
Distinguishing between these causes is important because their management differs. For example, iron deficiency may require iron supplementation, whereas haemolytic anaemia may require further investigations to identify the underlying cause.
Untreated significant anaemia can increase the risk of maternal complications and adverse pregnancy outcomes. Early testing helps the treating obstetrician determine whether supplementation, further investigation or closer monitoring is necessary.
Which Blood Tests Should Be Checked During Pregnancy?
The following investigations may be recommended depending on the patient's symptoms, medical history and initial results.
1. Complete Blood Count (CBC)
A Complete Blood Count (CBC) is the first-line investigation for assessing haemoglobin, red blood cell count, haematocrit and red blood cell indices, including mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). These parameters help classify anaemia and guide further testing.
At Dr. Dangs Lab, CBC testing includes automated analysis, with manual counter-checking of results as part of the laboratory's review process.

2. Serum Ferritin and Iron Studies
Ferritin helps assess the body's iron stores and is particularly useful when iron deficiency is suspected. Additional investigations, including serum iron, total iron-binding capacity (TIBC), unsaturated iron-binding capacity (UIBC) and transferrin saturation, may provide further information about iron status.
Ferritin levels can be affected by inflammation, so results should be interpreted alongside the patient's clinical history and other laboratory findings.

3. Vitamin B12 and Folate (Vitamin B9)
Vitamin B12 and folate are essential for normal red blood cell production. Deficiencies can interfere with the formation of healthy red blood cells and may cause macrocytic anaemia, in which red blood cells are larger than usual.
Testing may be recommended when blood indices, dietary history, symptoms or other clinical findings suggest a possible deficiency.
4. Peripheral Blood Smear and Reticulocyte Count
A peripheral blood smear allows laboratory professionals to examine the size, shape and appearance of red blood cells. A reticulocyte count measures the number of young red blood cells in circulation and helps assess how the bone marrow is responding to anaemia.
These investigations can provide useful clues when the cause of anaemia is unclear or when premature red blood cell destruction is suspected.
5. Haemoglobin HPLC or Electrophoresis
Haemoglobin high-performance liquid chromatography (HPLC) or electrophoresis may be recommended when thalassaemia or another inherited haemoglobin disorder is suspected. These tests help identify and quantify different types of haemoglobin.
They are particularly relevant when microcytosis persists despite adequate iron stores or when there is a personal or family history of a haemoglobin disorder. Depending on the findings, haemoglobin analysis and genetic counselling may also be recommended for both partners to assess the risk of inherited conditions in the baby.
6. G6PD (Glucose-6-Phosphate Dehydrogenase) Test
G6PD is an enzyme that helps protect red blood cells against oxidative damage. G6PD deficiency is an inherited condition in which reduced enzyme activity makes red blood cells more vulnerable to premature destruction, potentially leading to haemolytic anaemia.
During pregnancy, a G6PD enzyme activity test may be recommended when unexplained anaemia, suspected haemolysis, a relevant family history or other clinical findings raise concern about this deficiency. It may also be considered when a doctor needs to assess the risk associated with medications that can trigger red blood cell destruction in people with G6PD deficiency.
A CBC alone cannot confirm G6PD deficiency. A specific enzyme activity test is generally used to assess whether G6PD activity is reduced. However, enzyme activity can sometimes appear normal during or shortly after an episode of haemolysis because older red blood cells with lower enzyme activity have been destroyed and younger cells remain. In such cases, repeat testing may be necessary if clinical suspicion remains high.
Identifying G6PD deficiency can help doctors make informed decisions about medication safety and the evaluation of suspected haemolysis. However, G6PD testing is not routinely required for every pregnant woman and should be recommended according to clinical history and medical assessment.
At Dr. Dangs Lab, G6PD testing is available to support the investigation of suspected G6PD deficiency when advised by a healthcare professional.
7. Thyroid-Stimulating Hormone (TSH) Test
Thyroid disorders can occur during pregnancy and may coexist with anaemia. Thyroid function testing, particularly TSH, may be recommended when symptoms, medical history or initial results suggest a thyroid disorder. It may also form part of the evaluation when anaemia does not improve as expected with prescribed treatment.
Additional Tests When Haemolysis Is Suspected
When red blood cell destruction is suspected, doctors may recommend additional investigations such as bilirubin, lactate dehydrogenase (LDH), haptoglobin and a direct antiglobulin test (direct Coombs test). These tests help investigate whether haemolysis is occurring and whether immune-related mechanisms may be involved.
Depending on the findings, G6PD enzyme activity testing and other investigations may help identify the underlying cause.
Not every pregnant woman requires every test. The appropriate work-up should be individualised according to symptoms, pregnancy stage, medical history and initial laboratory results.
Who Should Consider Anaemia Testing During Pregnancy?
Anaemia testing is generally part of routine antenatal care, with repeat assessment guided by pregnancy stage, initial results and clinical recommendations.
Testing is especially important for women with:
-
A history of anaemia or iron deficiency.
-
Persistent fatigue, dizziness, breathlessness or unusual paleness.
-
A restricted diet or suspected nutritional deficiencies.
-
Known or suspected thalassaemia or another inherited blood disorder.
-
A family history of G6PD deficiency or another inherited red blood cell condition.
-
Abnormal CBC results or a poor response to prescribed iron supplementation.
-
Clinical findings suggesting haemolysis or premature red blood cell destruction.
Women with abnormal results may require additional investigations to determine the underlying cause. Severe breathlessness, fainting, chest pain or marked weakness warrants prompt medical assessment.

Why Timely Diagnosis Matters for Maternal Health
Identifying the underlying cause of anaemia is more useful than treating a haemoglobin number alone. Iron deficiency may require iron replacement, whereas folate or vitamin B12 deficiency requires targeted treatment. Inherited blood disorders, including thalassaemia and G6PD deficiency, need a different assessment and management approach.
G6PD deficiency is particularly important to recognise when haemolysis is suspected because certain infections and medications can trigger red blood cell destruction in affected individuals. Appropriate testing can help doctors identify the deficiency, assess potential risks and make informed decisions about treatment and medication safety.
At the same time, not every case of pregnancy-related anaemia is caused by iron deficiency or an inherited condition. A structured diagnostic approach helps the treating doctor select the most appropriate investigations and avoid unnecessary testing.
At Dr. Dangs Lab, laboratory investigations can support the evaluation of anaemia and suspected G6PD deficiency. A qualified healthcare professional should always interpret results in the context of the patient's symptoms, medical history, and stage of pregnancy. The treating obstetrician should guide treatment, supplement use, and further investigations.
FAQs Around Anaemia During Pregnancy
1. Which blood tests are recommended for anaemia during pregnancy?
Common investigations include a CBC, serum ferritin and other iron studies. Depending on the initial results and clinical history, a doctor may recommend vitamin B12, folate, a peripheral blood smear, a reticulocyte count, haemoglobin analysis, thyroid function testing or investigations for haemolysis.
2. Is a G6PD test necessary during pregnancy?
A G6PD test is not routinely necessary for every pregnant woman. It may be recommended when there is a family history of G6PD deficiency, unexplained haemolytic anaemia or another clinical reason to suspect reduced G6PD enzyme activity.
3. Can G6PD deficiency cause anaemia during pregnancy?
Yes. G6PD deficiency can cause haemolytic anaemia when red blood cells break down prematurely. Episodes may be triggered by certain infections, medications or other oxidative stressors. A doctor can determine whether G6PD testing is appropriate based on symptoms and medical history.
4. Can a CBC detect G6PD deficiency?
No. A CBC can identify anaemia and provide information about red blood cell indices, but it cannot confirm G6PD deficiency. A specific G6PD enzyme activity test is generally required to assess the deficiency.
5. Where can I get a G6PD test in Delhi?
Dr. Dangs Lab offers G6PD testing to support the investigation of suspected G6PD deficiency. Patients can contact the laboratory to enquire about testing, sample collection and other relevant details.
