HIV: This test measures p24 antigen and HIV antibodies and if negative 4 mos after exposure has an inordinately high likelihood that you are negative and will remain so if you do not have further exposures.

Yes: Such a test's result is conclusive even before 5 months. A person can then follow routine testing schedules after that, which means if a person is having sex with several people each year, she can tell her primary care doctor about her activities each year at her routine check-ups, and ask her primary care doctor for annual "STD and HIV screening" once per year. ...Read more

It's conclusive.: The p24 antigen is a viral core protein that appears in the blood as the viral RNA level rises following HIV infection. The test turns (+) 5-7 days after viral RNA appears in the blood. It is 89-100% as sensitive as viral RNA. This assay detects a level of antigen that approximately corresponds to an HIV RNA level of 30, 000 to 50, 000 copies/mL. ...Read more

They say hiv 4th gen duo is between 14-28 days, Will it make a difference if I go at 12 days to do test? Can it still detect p24 or not?

Follow the primary care doctor's recommendations, and live life safely and wisely. ...Read more

Around 50%: Roughly half of newly infected people would have a positive duo test at 10 days. If at truly high risk, like unprotected sex with a known infected partner, ask about an RNA test for the virus. However, heterosexually acquired HIV remains quite rare in the UK. If at lower risk, have another duo test at 28 days, which will be conclusive. Or get expert advice at an NHS GUM clinic. Good luck! ...Read more

How reliable (percentage of accuracy) of 4rd generation hiv test (duo test) at 14.5 day after exposure? Thank you very much
It is accurate if positive. However, two weeks is too soon to rule out infection. At six months after exposure, get a HIV nucleic acid test, if that is negative, it would be definitive indication of being HIV free.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.
