Hello, Thnx to contact us. I understand your concern. If I am your doctor I advice you that Tridot is the good test kit for diagnosis of HIV. It is a test based on Immunofiltration. It is not able to give result in early infection period but it is good test to detect HIV in later part of infection. You can test and rely on tridot after a three month duration of exposure. I will be happy to answer more of your concerns, kindly know me, Wish you a very good health at health care magic. Dr. Arun Tank. Infectious Disease.
