Welcome and thanks for posting your query to HCM.
According to your query the last test you had gone for was ELISA
for HIV after 7 months of exposure. If the person is HIV positive, it is quite unlikely for ELISA to come negative after 6 months of period. Generally in most of the cases we recommend to go for ELISA at 3 months of the period and then finally repeat it at 6 months which we consider as cut off for checking HIV. Now in your case all the three times it came negative so it is not at all a possibility of HIV. But even then you can simply repeat the test and can get the final confirmation of your nonreactive (negative) status to get the relaxation of your mind form HIV. Radiations do not cause any interference with tests done for HIV or on window period.
For the part of signs and symptoms of fever
, mouth ulcer
and swollen lymph nodes
– my dear friend there are end number of infections and diseases in this world which actually are more commonly causing these rather than HIV. Your radiation exposure itself could be one of the cause of the illness. So check your radiation status and meet a good physician near you who can treat the underlying cause at its best.
