Qitai SG I think you mean the other way round - you can't donate blood for 6 months after you have sex . And I think it should be 6 weeks. Pre-caution measure for HIV. Not sure about the exact incumbent period is.
Qitai SG There is a incumbent period in which there is no good way to tell if someone is infected. Hence, blood donation is not allowed during that period.
le cruz SG i’ve donated blood once before, but didn’t remember if i filled in a form to declare that i din not have sex within the last six weeks. but they did the blood test anyway.
2004Lancer SG the only persons suitable to donate blood is children coz they r the purest among us adults.....kakakakaka.......SAY!!!
