5th Month Pregnancy Blood Test
Introduction
Pregnancy is an exciting journey, but it also comes with regular checkups and tests to ensure both the mother and baby are healthy. One important milestone is the 5th month (around 20 weeks), when certain blood tests are recommended. If you're expecting and curious about what these tests involve, this guide will help you understand their purpose, what they check for, and how they contribute to a healthy pregnancy.
Why Are Blood Tests Done in the 5th Month?
By the fifth month, your baby is growing rapidly, and your body is undergoing significant changes. Blood tests at this stage help monitor:
- Maternal health (e.g., anemia, infections, or gestational diabetes)
- Baby’s development (e.g., genetic conditions or growth issues)
- Any complications that may need early intervention
These tests are routine and help doctors provide the best care for you and your baby.
Common Blood Tests in the 5th Month
Common blood tests are:
1. Complete Blood Count (CBC)
This test checks for:
- Anemia (low red blood cells) – Common in pregnancy due to increased blood volume.
- Infections – High white blood cells may indicate an infection.
- Platelet count – Ensures proper blood clotting during delivery.
Why it’s important: Anemia can cause fatigue and weakness, while infections may need treatment to protect the baby.

2. Glucose Screening Test (for Gestational Diabetes)
- A glucose challenge test is done between 24-28 weeks, but some doctors may start screening earlier if there’s a risk.
- You’ll drink a sugary solution, and blood will be drawn after an hour to check blood sugar levels.
Why it’s important: Untreated gestational diabetes can lead to complications like a larger baby, preterm birth, or high blood pressure.
3. Iron and Ferritin Levels
- Check iron stores in the body.
- Low iron can lead to anemia, causing tiredness and affecting the baby’s oxygen supply.
Tip: Eat ironrich foods like spinach, lentils, and lean meats. Vitamin C (oranges, tomatoes) helps with iron absorption.
4. Thyroid Function Test
- Pregnancy can affect thyroid hormone levels, which are crucial for baby’s brain development.
- Hypothyroidism (low thyroid) can lead to developmental delays if untreated.
5. Antibody Screening (if Rh negative)
- If your blood type is Rhnegative and the baby is Rh positive, your body may produce antibodies that can harm future pregnancies.
- A shot called Rh immunoglobulin (RhoGAM) may be given to prevent complications.
