The primary function of the TLC test is to evaluate the overall number of white blood cells in the body. White blood cells play a crucial role in defending the body against infections, allergies, and foreign substances. They are involved in the immune response and can be categorized into different types: neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
The Total Leucocyte Count (TLC) test, which measures the total number of white blood cells (leucocytes) in the bloodstream, may be required in various conditions to assess the immune system and diagnose or monitor certain diseases. TLC testing is commonly performed when an infection is suspected. An increase in white blood cell count, particularly the neutrophil count (neutrophilia), often indicates the presence of a bacterial, viral, or fungal infection. It helps healthcare professionals identify and monitor the response to infection.
The TLC Test (Total Leukocyte Count) is a simple blood test that can be performed in a laboratory. Before the test, the patient may be asked to avoid certain medications that may affect the results. During the test, our healthcare professional will use a needle to draw blood from a vein in the patient's arm. The blood sample will then be sent to our laboratory for analysis.
The reference range for TLC may depend on factors such as age, sex, and overall health. In adults, a normal TLC typically ranges between 4,500 and 11,000 white blood cells per microliter (??L) of blood.
