Total Leukocyte Count

Total Leukocyte Count

The total leukocyte count measures the number of white blood cells in the body. A high total leukocyte count may indicate an infection or inflammation, while a low count may indicate a weakened immune system or a viral infection.

  • Test Name Total Leukocyte Count (TLC)
  • Sample Type Peripheral Blood
  • Preparations Required No special preparation is needed for this test.
  • Report Time 4 Hours

The normal range for total leukocyte count depends on age, gender, and other factors, but normally falls between 4,500 and 11,000 cells per microliter of blood. These cells are crucial parts of the immune system. helping in the body's defence against infections and diseases. The test is often used to evaluate the immune system, diagnose diseases and monitor medical treatment

White blood cells are composed of five major types - Neutrophils, Lymphocytes, Monocytes, Eosinophils, and Basophils. Each has a different function in fighting off various infections and diseases. An imbalance in the number of these cells can indicate a potential health issue.

Frequently Asked Questions

The total leukocyte count, also known as the white blood cell count counts indicates how much white blood cells (leukocytes) are in a person's blood. It is typically expressed in thousands (K/μL) or millions (M/μL) of cells per microliter.

The total leukocyte count is primarily influenced by factors such as infection, inflammation, and certain medical conditions. Infections and inflammatory responses often lead to an increase in white blood cells, while certain conditions or medications can cause a decrease in the leukocyte count.

To calculate the total leukocyte count (TLC), a blood sample is typically collected and analyzed by a laboratory using specialized equipment. The TLC is determined by counting the number of white blood cells in a specific volume of blood, usually expressed as cells per microliter (K/μL or M/μL).

When white blood cells increase, it is often a sign of an infection, inflammation, or immune system response in the body. Elevated white blood cell counts can help healthcare providers diagnose and monitor various medical conditions.

Conditions including bone marrow abnormalities, viral infections, certain drugs, or radiation therapy can all contribute to the decline of white blood cells. A lower white blood cell count raises the risk of infections and impairs immunity.
