Other Names for the Total Leucocyte Count (TLC) Test

• White Blood Cell (WBC) Count
• Leukocyte Count

What is the normal range for white blood cell count?

The normal range for white blood cell count varies depending on age, sex, and other factors. Generally, the normal range for adults is between 4,000 and 11,000 white blood cells per microliter (mcL) of blood.

Detailed information about the test

The TLC test measures the total number of white blood cells in a blood sample. White blood cells are crucial for fighting infections and maintaining a healthy immune system. Abnormal results, either high or low, can indicate various health conditions, ranging from infections and inflammation to autoimmune diseases and blood cancers.

Purpose of the test

The Total Leucocyte Count (TLC) Test is used for various purposes, including:

• Detecting Infections: Elevated white blood cell count (leukocytosis) can indicate an infection, such as bacterial, viral, or fungal infections.
• Identifying Inflammation: Increased WBC count may also suggest inflammation in the body, which can be associated with various conditions like autoimmune diseases or tissue injury.
• Diagnosing Blood Disorders: Abnormally low or high WBC counts can indicate blood disorders like leukemia or lymphoma.
• Monitoring Health Conditions: The TLC test is used to monitor the progression of infections, inflammatory diseases, or blood disorders and assess the effectiveness of treatment.
• Evaluating Overall Health: It is often included in a complete blood count (CBC) as part of a routine health checkup to assess overall health and screen for potential health problems.

Test Complete Information

The TLC test is a simple blood test. A small sample of blood is drawn from a vein in your arm and sent to a laboratory for analysis.

How the test works

2. Laboratory Analysis: The blood sample is analyzed in a laboratory to count the total number of white blood cells.
3. Results Interpretation: The results are typically reported as the number of white blood cells per microliter (mcL) of blood.

Normal and Abnormal Test Levels
