Can HIV be detected by blood test?

Blood test is a common medical examination method. Generally speaking, AIDS can be detected through blood test. We know that AIDS is a relatively serious disease. If you suspect that you have AIDS, you must go to the hospital for a formal examination in time, especially within 72 hours of high-risk sexual behavior. Let us briefly understand this aspect below.

Can HIV be detected by blood test?

Generally speaking, AIDS can be detected by blood test. AIDS is a very difficult infectious disease that can be detected through blood tests. So can a blood test detect AIDS? Let's take a closer look!

A blood test can detect AIDS. AIDS is an immune disease. The main diagnostic method for this viral infectious disease is blood testing. By analyzing the specificity and concentration of immune proteins in the blood, it is possible to confirm whether the person is infected with the virus and detect AIDS.

Can blood tests detect AIDS?

A blood test cannot detect AIDS. A routine blood test is a routine examination. It can only detect a low white blood cell count, but cannot diagnose a specific disease or detect the specific HIV virus. In other words, it can detect a serious decrease in immunity, but cannot confirm AIDS.

The physical examination is simpler than the routine blood test done in the hospital. The items checked are all functional items of the body's organs, mainly liver function and kidney function. It generally does not involve the immune area, has no guiding role in AIDS, and cannot diagnose AIDS.

How long does it take to get the results of a blood test for HIV?

HIV test results are usually available on the same day, except on holidays. The test results are negative, weakly positive, and positive. Positive and weakly positive mean that the person may be infected with the virus and further confirmatory testing is required.

How to diagnose AIDS? There are currently two main methods for AIDS testing. One is the test paper test, which involves dropping blood on a test paper specifically for AIDS testing to see its specific response. It can confirm that AIDS is positive, but the accuracy is not very guaranteed. The other is immunofluorescence analysis, which can most intuitively see the amount of AIDS antigens in the body through targeted antigen recognition and fluorescent labeling of HIV, with an accuracy rate of 100%.
