Total Leucocyte Count + Differential Leucocyte Count

Leukocytes, or white blood cells (WBCs), are part of the immune system and help protect the body from infections and diseases. There are five types of WBCs: basophils, eosinophils, lymphocytes, monocytes, and neutrophils, each playing a different role in fighting infections. The Total Leucocyte Count + Differential Leucocyte Count test measure two key parameters of WBCs: Total Leucocyte Count (TLC) and Differential Leucocyte Count (DLC). TLC shows the total number of white blood cells in the blood, while DLC breaks down the WBCs into different types and shows their percentage. These tests are important for evaluating the immune system and detecting conditions like infections, allergies, etc., or blood cancers.

The Total Leucocyte Count + Differential Leucocyte Count test identify infections, evaluate immune system health, and monitor treatment response to therapy such as chemotherapy, etc. Also, they help in the early detection of diseases such as leukemia, lymphoma, and allergic reactions. They can also be done as part of a complete blood count (CBC) for routine health screening to provide insights into your overall health. 

By determining the count of white blood cells present in the body and their relative proportions, TLC and DLC tests are helpful in determining how the immune system is responding to various conditions. A raised TLC (leucocytosis) may reflect an infection, inflammation, or blood cancer, while a low TLC (leukopenia) suggests a weakened immune response resulting from bone marrow disorders or viral infection. On the contrary, DLC may help pinpoint which of those white blood cells is involved, which is crucial in supporting doctors in diagnosing and differentiating diseases. 

No special preparation is needed for the Total Leucocyte Count + Differential Leucocyte Count test. Eat or drink normally as per the daily routine. However, it is important to inform the doctor about any medications, supplements, medical conditions, or vaccination history before the test, as these factors may potentially influence the test results.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. The test results will help the doctor determine the medical condition, make recommendations for lifestyle modifications such as diet and exercise, decide whether or not medication will be required to manage the condition, and formulate the overall treatment plan.
