What is TC DC?
There are five types of white blood cells, each with different functions: neutrophils, lymphocytes, monocytes, eosinophils and basophils. The differential reveals if these cells are present in normal proportion to one another, if one cell type is increased or decreased, or if immature or abnormal cells are present. This information is helpful in diagnosing specific types of illnesses that affect the immune system. White blood cells are made in your bone marrow or lymphoid system. They protect your body against infection and aid your immune system. If an infection develops, white blood cells attack and destroy the microorganism causing the infection.
Total Count and Differential Count test is performed on a sample of blood to measure the level of Total Count, Neutrophils, Lymphocytes, Monocytes, Eosinophils, and Basophils in the blood. It is performed to detect Blood Cancer and Infection. Details: TC is total count or the number of WBCs/ white blood cells per cubic mm of blood
DC is differential count, which expresses the configuration of the WBCs in the blood.
An HB test can tell how much hemoglobin you have in your blood.

That’s common if the blood sample will be used for additional testing. Your doctor will give you the required instructions.
Uses
The normal result for TC DC for Total Count is 4000 to 11000 cells for Unisex gender and for all age groups.
- Neutrophils is 40-80% for Unisex gender and for All age groups.
- Lymphocytes is 20-40% for Unisex gender and for All age groups.
- Monocytes is 2-10% for Unisex gender and for All age groups.
- Eosinophils is 1-6% for Unisex gender and for All age groups.
- Basophils is 1-2% for Unisex gender and for All age groups.
