Best Answer: It depends a lot on your immune system, your gender, and which STD we're talking about. Here's a short list: CHLAMYDIA-often asymptomatic for both genders. CYTOMEGALOVIRUS (CMV) - 85% of the general population has it, but nobody shows any symptoms until they're in real big trouble.GONORRHOEA-symptoms usually appear in 2-5 days, though some people are asymptomatic for up to a year.ere's a short list: CHLAMYDIA-often asymptomatic for both genders.

âI am on warfarin (Coumadin Â®). Can I donate blood?â No. A person on a blood thinner (anticoagulant), like warfarin, will not be accepted as a blood donor because of the risk of bleeding to him/her when the vein in the arm is entered with a big needle or venous catheter during the donation process.
Donating blood is relatively simple and entirely safe, however, taking just an hour and requiring little preparation. There is little risk of adverse reaction when donating blood, and you can donate whole blood every 56 days; blood platelets every three days, up to 24 times a year. However, a few people may feel dizzy or faint during the process.
