There is no test available. It maybe worthwhile considering Post Exposure Prophylaxis

Rapid HIV test is only helpful at this stage to establish your pre-exposure HIV status. 

You are at risk of HIV if 

  • You have several sexual partners.

  • You had unprotected sex with someone who is or could be HIV-positive.

  • You have injected drugs using shared needles or other equipment.

  • You have had any sexually transmitted disease, including herpes, hepatitis, or TB.

  • You have had sex for drugs or money.


PEP is a month-long course of emergency medication taken to try to keep HIV from making copies of itself and spreading through your body.

Post Exposure Prophylaxis is indicated if

  1. You are unsure of your partner’s HIV status. 

  2. If the person is a causal sex worker. 

  3. If you are immunosuppressed.

Blood test with western blot is also indicated if you have a positive rapid HIV test. 


HIV (Human Immunodeficiency Virus) is recognised as the etiologic agent of Acquired Immune Deficiency Syndrome (AIDS). The virus is transmitted by sexual contact, exposure to infected blood, certain body fluids or tissues. HIV infection is marked by increasing levels of viral replication and the emergence of more virulent strains. This process causes the destruction of the immune system. 

ICARE Medical provides Alere HIV Combo Test, a qualitative rapid HIV test. This kit is for the detection of HIV-1 p24 antigen and antibodies to HIV-1 and HIV-2.
