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.
Physically small people are not acceptable as blood donors as they have lower blood volumes and may not be able to safely lose a full pint of blood. One may not donate blood while one has the flu. But one can donate blood after exposure to someone with the flu provided the potential donor feels and has no symptoms. A minimum age limit exists as to how old a person must be in order to donate blood (usually age 17). There is no maximum age limit. Pregnancy and recent childbirth rule one out as a blood donor.
