Pregnancy requires structured medical monitoring to ensure the safety of both mother and baby. Blood tests are an essential part of antenatal care.
Many expecting mothers ask, “How many blood tests will I need during pregnancy?” The answer depends on individual health, medical history, and risk factors. However, there is a standard trimester-wise pattern followed in most pregnancies.
Below is a clear and practical breakdown…
First Trimester (0–13 Weeks):
This stage involves the maximum number of blood tests, as baseline screening is very important.
Common First-Trimester Blood Tests:
- Blood Group and Rh Typing
- Complete Blood Count (CBC) – To check hemoglobin and anemia
- Thyroid Function Test (TSH)
- Blood Sugar (Fasting / Random)
- HIV Screening
- HBsAg (Hepatitis B)
- VDRL (Syphilis screening)
- Rubella IgG
- Urine Routine (often done alongside blood tests)
Typically, 7–9 blood investigations are done in early pregnancy.

Second Trimester (14–27 Weeks):
In this phase, fewer blood tests are required unless medically indicated.
Common Tests:
- Double Marker Test (if advised in early second trimester)
- Glucose Screening Test (GCT / OGTT) – Around 24–28 weeks
- Repeat CBC (to recheck hemoglobin)
Usually 2–3 blood tests during this trimester.
Third Trimester (28 Weeks Until Delivery):
Monitoring continues, especially for anemia and diabetes.
Common Tests:
- Repeat CBC
- Repeat Blood Sugar (if required)
- Repeat HIV / HBsAg (as per hospital protocol)
Around 2–4 blood tests, depending on clinical condition.
Total Number of Blood Tests in Normal Pregnancy:
In a low-risk pregnancy, a woman may undergo approximately:
10–15 blood tests across 9 months.
The exact number varies depending on:
- Previous medical history
- Twin pregnancy
- Thyroid disorder
- Gestational diabetes
- High blood pressure
- Anemia
High-risk pregnancies may require additional testing.
Why Are So Many Tests Necessary?
