People really need to stop thinking of donating blood as a means to get free medical testing, and they need to stop thinking that the testing done on donor units is 100% accurate. They only test the units for ANTIBODIES to the diseases. Antibodies don't appear in the blood stream for at least WEEKS, if not MONTHS after contracting a disease. So, you can contract HIV and have the virus in your blood and you can donate it to someone else, but if you contracted it recently, the tests are NOT going to detect the antibodies yet and that unit of blood is going to appear safe, even though it's contaminated. That is why they ask people with high-risk lifestyles to please not donate blood. It's the only way to attempt to keep the blood supply as safe as possible. But, back to your question.....people are routinely checked for HIV, Hepatitis A, B & C, & Syphillis through blood tests. Gonorrhea and Chlamydia are usually screened for with a swab of vaginal secretions. Trichomonas often shows up in a routine urinalysis, but they can also swab for that. I believe those are the "biggies". Gonorrhea and Trichomonas usually have pretty obvious symptoms, so the docs don't usually test for those unless a patient has symptoms (heavy, smelly discharge, a sore or "chancre" with gonorrhea....trich has a green, fishy-smelling discharge).
