Sort of wondered. Residual guilt, I guess, of my guilty and repellant sin being found out, as well as the true belief in the subject topic. Anyone know the answer? ---

I recall having some morning nookie on the day of a doctor’s visit once, and then, while filling up the pee cup, wondering the same thing. The tests all came back fine, though. Hopefully, your mileage won’t vary. ---

Don’t they test for protein? Does ejaculate contain protein? ---

Any time I’ve seen instructions on how to give a urine sample, it says to start peeing, stop the flow and then fill the cup. I suspect it’s to clear out impurities before you take the sample. ---

> [@AaronX](#): > > Don’t they test for protein? Does ejaculate contain protein? Um…:eek: True story but when I went for my high school junior year physical they told my ma that my urine sample tested high for protein content and they were concerned about kidney problems/infection. Blood tests were fine, though. 10 days later I took another urine test and everything is find. I guess we’ll never know if the hand-job i got from my girlfriend about 3 hours before the first test had anything to do with it. ---

My friend also tested high for protein and was back to normal a few days later. They told him exercise can cause this. ---

Well, so it _does_ mess up a pee test; these reports say that you had to come in (heh) for a second test. IANAD, but high protein levels can indicate a compromised kidney. ---

Sorry, now see **pkbites** mentioned the kidney.
