What Are the Required Pregnancy Blood Tests

Prenatal blood tests vary by trimester. Each test is designed to detect specific conditions early — before they become complications. Our certified lab technician collects your sample at home and sends it to our accredited laboratory.

First Trimester Blood Tests (Weeks 1–12)

The first trimester is the most critical period for fetal development. Required tests include:

• HCG (Pregnancy Hormone) — Confirms pregnancy and tracks hormone levels to ensure healthy development
• Complete Blood Count (CBC) — Screens for anemia and infection
• Blood Type & Rh Factor — Essential if Rh-negative; prevents Rh incompatibility with the baby
• Fasting Blood Sugar — Detects pre-existing diabetes before pregnancy complications arise
• Thyroid Function (TSH) — Thyroid disorders in early pregnancy affect fetal brain development
• Vitamin D & Folic Acid — Deficiency increases risk of neural tube defects
• Hepatitis B & C, HIV — Mandatory screening
• VDRL (Syphilis) — Mandatory
• Rubella IgG/IgM — Confirms immunity to German measles
• Urine Analysis — Detects silent urinary tract infections common in pregnancy

Second Trimester Blood Tests (Weeks 13–26)

• Triple Screen / Quadruple Screen — Weeks 15–20, assesses chromosomal abnormality risk
• Gestational Diabetes Test (OGTT) — Weeks 24–28, requires 8-hour fasting
• Complete Blood Count (CBC) — Follow-up for anemia as pregnancy progresses

Third Trimester Blood Tests (Weeks 27–40)

• Group B Streptococcus (GBS) — Weeks 35–37, protects baby during delivery
• CBC and Iron Studies — Monitors anemia before labor
• Coagulation Profile — For mothers with high-risk pregnancies
• Blood Pressure & Urine Protein — Rules out preeclampsia
