Many of the victims and even non victims don't know the meaning of the so called CD4 count and how it determine the fate of the patient.
The CD4 count is a test that measures how many CD4 cells you have in your blood. They are a type of white blood cell, called T-cells, that move throughout your body to find and destroy bacteria, viruses, and other invading germs.
CD4 test help the doctor to know how much damage has been done to your immune system and what's likely to happen next if antiretroviral treatment (ART) is not initiated.
This means All persons with HIV should be taking ART regardless of whether the CD4 count is high or low. However,the CD4 count should increase in response to effective ART.
The virus grabs on to the surface of a cell(white blood cell), gets inside, and becomes a part of it. When the infected CD4 cell dies, it releases more copies of HIV into he bloomstream.This weakens the immune system of the body.
What's the implications of low or high CD4 count?
A test can give a result of a low or high CD4 count. However, health sites claims that a normal CD4 count is from 500 to 1,400 cells per cubic millimeter of blood.
When at high figures,it means that the ART is working perfectly and the patient may lolive longer. Alternatively, when the CD4 counts decrease over time in persons who are not receiving ART and hit levels below 200 cells per cubic millimeter, patients become susceptible to a wide variety of opportunistic infections that finally leads to a death.
It is therefore advisable that everyone who is HIV-positive should take antiretroviral therapy regardless of their CD4 count and whether or not they have symptoms.
