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.

No, I realize some people are totally freaked out by needles or blood, to me that doesn't mean they should be lower on a list for receiving blood or plasma if needed. 2  lorraine mosiaAugust 18, 2013 at 7:41 AM. wht do i do if i want to donate blood. 3  AnonymousAugust 22, 2013 at 4:08 PM.
