Question

How is CD4 count involved in monitoring HIV infection? What is another laboratory method to monitor the disease?

Answer 1

Answer) HIV infection is a viral infection caused by the Human Immunodeficiency Virus. there are CD4 T-cells which fight against the infection. assessing the CD4 count help us determine the severity of the infection. in a normal human being, CD4 T-cell count falls between 500-1500 per cubic millimeter of blood. having a CD4 count below 200 represent the heavy infection. in case of viral HIV infection, CD4 count is seen below 200 per cubic millimeter of blood for a longer duration which may fall as low as 20 per cubic millimeter of blood which is undetectable.

Another laboratory method to monitor the disease is directly assessing the viral load through testing for plasma HIV-1 RNA. the concentration of HIV-1 RNA in blood plasma represent the viral load.
