You would have to have it tested. Ask a doctor about it.

Well, I know there is time period of 8 years of school for the degree. A test called the MCAT seem to be part of this as well and it has to be completed before going to school in order to be doctor.
Since Chlamydia is a "silent" std -you wouldn't know you had it unless you got tested. Or when did get tested, and contracted the virus just a few days before getting tested, it will go unnoticed. What happened with me is, a guy I had unprotected sex with got it from me... like a year ago but when he had gotten tested it didnt show, so he didnt know he had it - but he got tested again and it showed - so i went and got tested but it didnt show, yet my doctor gave me the antibiotics anyways - Just in case.
I believe you can go to your doctor to be tested for most or all allergies. If you have had any sort of reaction (rash, trouble breathing, etc) to watermelon before, it's probably safe to stay away from it.
