What is the normal viral load and CD4 count?

A healthy immune system normally has a CD4 count ranging from 500 to 1,600 cells per cubic millimeter of blood (cells/mm3), according to HIV.gov. When a CD4 count is lower than 200 cell/mm3, a person will receive a diagnosis of AIDS.

Which is more important viral load or CD4?

While the CD4 count is an indicator of immune status and treatment efficacy, the viral load is arguably the more important measure when antiretroviral therapy begins.

What viral load is undetectable?

The point at which a viral load is classified as being undetectable may vary across different countries depending on the tests available. But so long as your viral load is under 200 copies per millilitre, you’re considered virally suppressed and unable to pass HIV on.

What CD4 count is undetectable?

Higher numbers of CD4 cells indicate that the person’s immune system is stronger and better able to fight off infections. When the viral load reaches less than 200 copies/ml of blood, doctors consider that HIV is undetectable.

How often to have your CD4 count and viral load tested?

A healthcare provider will likely conduct CD4 counts and viral load tests more often at the beginning of HIV therapy or with any changes in medications. Most people living with HIV should have lab tests performed every three to four months, according to current lab test guidelines.

What does the viral load and CD4 count indicate?

While the CD4 count is an indicator of immune status and treatment efficacy , the viral load is arguably the more important measure when antiretroviral therapy begins. The viral load measures the concentration of virus in the blood, also known as your “viral burden.”.

What does “viral load” mean?

Viral load is the amount of viral particles present in the blood stream, as detected by the proteins or building blocks of the virus, the RNA .

What are CD4 T-cells and why are they important?

CD4 cells are white blood cells called T lymphocytes or T cells that fight infection and play an important role in immune system function. CD4 tests measure the number of these cells in the blood and, in conjunction with an HIV viral load test, help assess disease status in a person who has been diagnosed with human…
