TLC Blood Test

What is the TLC Blood Test?

The Total Leukocyte Count (TLC) blood test is used to determine the number of white blood cells
in the body. The main role of leukocytes (white blood cells) is to protect the body against infectious diseases and foreign invaders.

Different Types
of White Blood Cells


Protect the body from bacterial and viral infections.


Help your body fight allergies and also prevents the blood from clotting.


Defend the body against viral, bacterial, fungal and protozoa infections. They are also responsible for fighting cancer cells and removing dead tissues in the body.


Help heal damaged tissues and fight bacteria and fungi.


Kill parasites and cancer cells. They also help in fighting allergies.

Why is a TLC Blood Test Done?

Your doctor may order a TLC in blood test to:

  • Diagnose and differentiate between chronic and acute infections
  • Diagnose some types of cancer such as leukemia
  • Diagnose an immune system disorder
  • Check out the effects of chemotherapy
  • Identify allergic reactions in the body

How is the Procedure Performed?

TLC blood test is performed just like any standard blood test. The doctor will take your blood sample and TLC is estimated either through a microscope or a hemocytometer.

Preparing For a TLC Test
There is no need to take any precautions before undergoing a TLC test, however, remember to inform your doctor about any medications that you are taking as they might affect the test results.

TLC Blood Test Normal Range
TLC normal range is between 4,000 and 11,000 cells per cubic millimeter of blood. TLC normal range in male and also TLC normal range in female are the same as an above mentioned range.

Causes of High or Low TLC Count

  • High TLC count may be due to a number of reasons including allergies, cancer, bacterial or viral infections, rheumatoid arthritis, and tuberculosis
  • Low TLC count may be caused by viral infections that prevent the production of WBC, anemia, vitamin deficiency, rheumatoid arthritis, dengue, and typhoid
