The white blood cells (WBCs) or leucocytes present in the blood safeguard the body from diseases and infections. A total leucocyte count (TLC) test is a blood test that checks the presence of any pathogens in the body or if it is fighting any infections or diseases. Mentioned below are key things one needs to know about the TLC test: -
Purpose
The total leucocyte count test is vital to check the overall well-being of an individual and to analyse any pre-existing disease in their body. Here are the reasons why this test is conducted:
- To monitor the immune system’s functioning: The number of white blood cells in the body determines if the immune system is functioning properly or not. If the count of leucocytes is more or less than the normal range, then it can mean that the immune system is unable to fight a disease or infection in the body.
- To evaluate inflammatory conditions: Inflammatory conditions are caused when the body sends out signals to fight pathogens. A TLC test helps evaluate if inflammation is increasing or decreasing.
- To check for infections: The abnormal levels of white blood cells can indicate that the body is fighting some kind of infection. By taking a TLC test, an individual can determine the severity of the infection and how much it has spread in the body.
- To diagnose blood disorders: The TLC test is one of the key blood tests that can help diagnose any blood disorder including leukaemia and lymphoma.
- To observe bone marrow disorders: Many bone marrow disorders reduce the number of WBCs in the body. Taking a TLC test can help observe the criticality of the disorder one may have.
The normal range of the TLC test can indicate if an individual is healthy and free from infections and diseases. It can differ from person to person based on their age and gender.
It is essential to take a well-priced TLC test from a reputed pathology lab to get accurate results. This can help the doctor recommend the best course of action for the individual.
