Is it good idea to donate blood after testing Hiv neagtive more than 4 times. Testing after 3 months, 6 months, 14 months, 19 months and 20 months from the last exposure...
Why i'm i asking this question?? It is because i donated blood before with my friend when i abtained from sex. So this time again he is asking me to donate blood again (I'm from africa)
