HIV has been in the society for decades now and the rise of the virus is not slowing down. This rise is contributed by misdiagnosis or failure to get tested. Most youths who are the highly affected have resulted to self test kits which they use hours before intercourse.
However this method has it's shortcomings since truly knowing your status cannot be easily noted. The following are the three reasons why youths are trapped into HIV by having tests before unprotected sex.
There are three types of HIV tests. Nucleic Acid test, This is the most accurate and most expensive HIV test. Not routinely done except for those at high risk.
NAT is relatively expensive and is preferred on its ability to identify the virus sooner than the other types of HIV tests, 10-33 days after exposure.
The second type are HIV antibody tests, these rely on antibodies developed towards the HIV virus. Antibodies are produced by your immune system when exposed to an offending agent like HIV.
Blood samples can be drawn from the vein, finger prick or oral swabs can be used. Antibody tests detect the virus 23-90 days after exposure. Antibody tests with blood drawn from the vein are more accurate than finger prick or oral swab samples.
Antigen/antibody tests detect HIV 18 to 90 days after exposure. Antigen/antibody tests done in lab with blood drawn from vein are more accurate than rapid antigen/antibody tests with finger pricking.
Through this difference in infection and detection period it's hard to be assured that you or your spouse is not infected. Doctors advice on using condoms for strangers and regularly being tested in every three months.
