The normal range for a CD4 count in an HIV negative person is between 400 and 1,600. This will cover 19 out of every 20 people (95%). But 1 in 20 HIV negative people (5%) have a normal CD4 count that is either less than 400 or higher than 1600. HIV negative people outside this range are still very healthy.
What can cause low CD4 count besides HIV?
In adults, HIV is certainly the most common cause of CD4 lymphocytopenia, but other causes, such as infections, autoimmune diseases, immunosuppressive therapy, lymphoma and idiopathic forms need to be considered.
What causes CD4 count to drop?
An infection like the flu, pneumonia, or a herpes simplex virus (including cold sores) can make your CD4 count go down for a while. Your CD4 count will go way down when you’re having chemotherapy for cancer.
What happens when your CD4 count is very low?
AIDS is diagnosed when your CD4 count is extremely low. AIDS is the most severe form of HIV infection. It badly damages the immune system and can lead to opportunistic infections. These are serious, often life-threatening, conditions that take advantage of very weak immune systems.
Can you recover from low CD4 count?
Yes. There are people who have started ARV treatment with a very low CD4 count-sometimes even 1 or 2 cells. The majority of them have recovered their immune system as a result of the ARV therapy.
What happens if CD4 count is less than 50?
This is a type of bacterial infection. It often presents in people with severely compromised immune systems (CD4 cell counts of less than 50). If these bacteria enter the bloodstream, it often results in death.
Can you test negative if your viral load is undetectable?
Having an undetectable of zero viral load does not mean you are HIV negative. If you were to do another HIV antibody test it would come back as being positive.
Can you go from undetectable to detectable?
People also become detectable when they stop taking their HIV medications or take them only partially. It may take between a week to several weeks after stopping HIV treatment for HIV to become detectable again, but people will see the levels of virus in their body go up to detectable levels.
How long can someone stay undetectable?
A person’s viral load is considered “durably undetectable” when all viral load test results are undetectable for at least six months after their first undetectable test result. This means that most people will need to be on treatment for 7 to 12 months to have a durably undetectable viral load.
Can you be undetectable without medication?
It is very unusual to have an undetectable viral load without treatment, but a very small proportion of HIV positive people, known as elite controllers, have undetectable viral loads less than 50 copies/mL for years without treatment. This is very rare and only about 1-in-300 HIV positive people are elite controllers.
A low CD4 count means that HIV has damaged your immune system and may be making you ill. HIV treatment will strengthen your immune system and extend your life. While your CD4 count is low, you may also need to take antibiotics to prevent infections.
What does low CD4 mean?
A low CD4 count indicates that your immune system has been affected by HIV and/or the disease is progressing. At CD4 counts less than 200 cells/mm 3, the immune system can no longer keep opportunistic infections in check.
What is AIDS T cell count?
A T cell count may also be known as a thymus-derived lymphocyte count or a T lymphocyte count. If you’re being treated for HIV, this test may be known as a CD4 cell count. Some T cells contain a CD4 receptor.
