You may have heard about CBC test and probably even had one during your lifetime. Many things change during pregnancy – particularly your diet and lifestyle. So is a CBC test really necessary during pregnancy? Read on to find out that and much more.

What Is Cbc Test During Pregnancy?

CBC stands for complete blood count- this form of blood test is basically helpful when it comes to getting information about the numbers of different blood cells present in the body, particularly red blood cells, white blood cells and blood platelets.

In general, a CBC test includes the count of white blood cells (leukocytes) in the body to point out the presence of any possible infectious conditions. It also helps determine the amount of red blood cells in the body, which could help diagnose conditions such as polycythemia (increase in red blood cells) and anaemia (lower red blood cell count).

To add to that, a CBC test also measures the levels of haematocrit, haemoglobin and differential

count of white blood cells. (1)

Why Is Cbc Blood Test During Pregnancy Needed?

A CBC test usually helps your doctor get a better idea of any illnesses you may be suffering from, and may also help him diagnose fatigue, weakness, infections and other deficiency conditions such as anaemia. Infact, a CBC test is probably the first test recommended during pregnancy.

A CBC test during pregnancy is required for several reasons including:

  • Measurement of haemoglobin content.
  • Measurement of haematocrit or packed cell volume.
  • Measurement of blood platelets that play a role in blood clotting.
  • The amount of individual white blood cells (monocytes, lymphocytes, neutrophils, basophils and eosinophils). These numbers could prove to be helpful in the detection of any infections whatsoever.
  • The amount of red blood cells present in the blood which could helpful in the early detection of any forms of deficiency (anaemia).

In some cases, your doctor may also have a blood smear test done to rule out any possible conditions such as sickle cell disease, malaria, leukemia and other blood diseases.

CBC test is actually one of the most simplest tests carried out during pregnancy, and is limited to merely drawing blood from the vein. There may be a small bruise at the site from where the blood is drawn, but the blood flow through the area usually stops in a couple of minutes.
