It varies depending on the particular type of test they do and how long the person has had the virus. Because the most common tests look for antibodies, you have to have had the virus for awhile for the test to be able to pick up on it.
If someone contracted the virus over three months ago most tests are 99.7% accurate at that point.
No you can't but you can get AIDS if the person that left the blood had AIDS.
to test for aids
A blood test is accurate at any time.
Yes. The home tests aren't accurate and only the blood test is the accurate one.
To check on the presence of aids requires a blood test.
Depends on what type of blood test you take. Regular blood tests do not show AIDS, unless you ask for the facility to look for it. If you have a blood test done for, as an example, being a blood donor, then they will look for AIDS
The first blood test for AIDS was developed in 1985. At present, patients who are being tested for HIV infection are usually given an enzyme-linked immunosorbent assay (ELISA) test for the presence of HIV antibody in their blood.
A blood test is required to verify.
yea if the person before you has aids or STD
You should discus this with you Doctor. They do not automatically test blood for H I V or AIDS unless told to
NO, in fact a normal AIDS test doesn't even test for the virus itself, it test as to whether or not your body is making the antibodies to the virus. a HIV, AIDS test is separate from other blood tests and must be asked for specifically.
Blood is always more accurate as it is a direct test - breath is indirect.
