it is often a mystery once your urine leaves the office and heads to the lab. over the years i have had sample contaminated by the lab spilled "lost in transit" (how in the world can someone lose a cup of urine? ) or in some cases there were so many different bacteria in your urine (many that are from the skin or vaginal area) that an accurate result could not be determined. it is best to do it again. clean thoroughly. pee a little bit and then stop. then collect the specimen.
can doctors mistakenly think a urine sample is contaminated when it's actually an illness? . the nurse called and said my sample was contaminated by i know i cleaned thoroughly and didn't touch the cup before during or after. and i did a clean catch. is it possible that a bacteria or something made it appear to be contaminated?
