TB is TB. HIV is HIV. If you both have tested negative after 3 months from your last unprotected sex then you don't have HIV. Yes the ELISA will pick of Group M.
thank you for yor answer do you know if it will pick up all of the subtypes like a-k please thank you
Just because you have HIV does not mean you have TB. But here is the catch, around 30% of the worlds population carry TB, 10% of that population will eventually contract active TB wich can be deadly if not treated ASAP. Even those on treatment could possibly die due to the disease progress, or the medications used to treat TB.
Now, those that have been exposed to TB but have not gotten sick from TB have what is called "Latent TB" again, 30% of the world popultaion is in this situation. If you have latent TB, this means TB is in your body, but your body has been able to surpress it, but it is still in you... alive and well.
If a person with Latent TB was to contract HIV, then this person could no longer supress the TB & then TB blossoms, turns active, the person gets sick and usually dies.
Why folks believe TB and HIV go hand in hand is because most people never become ill form TB, but when they contract HIV, they certainly can.
If you want to know your TB status, take the Quanti Feron Gold test & this is a definitive test. If you test positive, it means you have TB in your body, it does not mean you are or will become sick from TB.
