CD3 / CD4 / CD8 Count near me in Rajkot

The immune system is the body’s defense against germs and illnesses. A vital part of this defense is a group of white blood cells known as T-cells. The CD3 / CD4 / CD8 Count test measures the number of different types of T-cells to see if the immune system is working properly.

• CD3+ T-cells: CD3 is a marker found on all T-cells. While T-cells play a key role in the immune response, CD3 itself identifies these cells and does not directly carry out immune functions.
• CD4+ T-cells (Helper T-cells): These cells tell other immune cells what to do to fight an infection.
• CD8+ T-cells (Cytotoxic T-cells): These cells directly kill infected cells and cancer cells.

The CD3 / CD4 / CD8 Count test measures the percentages and absolute counts of these T-cells and calculates the CD4/CD8 ratio. This ratio is an important indicator of immune health. For example, in HIV, the virus specifically targets CD4 cells, causing their number and the CD4/CD8 ratio to drop. This change indicate weakening of the immune system, which makes a person more likely to get infections. The test is often used to monitor the progression of HIV and how well a person is responding to treatment. It is also useful for evaluating other conditions that affect the immune system. 

No special preparation is needed for this test. Inform the doctor about all medications being taken, as some may affect the results.
