What does a medical assistant report when a urinalysis produces a false positive result for a medical condition?

A positive result, obviously, since the assistant has no way of knowing that it is a false-positive. It is up to the doctor to consider the odds that the test was a false positive (see: test specificity and sensitivity) together with clinical signs, symptoms, history, epidemiology, and the results of other tests in making a diagnosis


Did one pregnancy test was positive and then second came out negative?

Wait a few days and take another test. If you still aren't sure, go see a doctor. But odds are, if you got one positive, you're pregnant. It's very unlikely to get a positive and not be pregnant. It's more common to get a negative and be pregnant.


Can stress cause pregnancy symptoms?

MOST definitely. There is even a psychological disorder in which your body will actually produce a false pregnancy -- ie. the hormone released in urine, the tender breasts, even the growing belly. If you stress about having symptoms of a pregnancy, odds are your brain will be alert for any and all symptoms that might confirm it. Therefore making you think you are pregnant.

How do MMA odds work?

In MMA (and other sports) the favored fighter is assigned a negative odds (e.g. -410) by the oddsmakers/bookmakers while the underdog fighter is assigned a positive odds (e.g. +350).If you take a bet on the favored fighter (with negative odds), betting that number (e.g. ($410) can win you $100 assuming the odds shown above.If you take a bet on the underdog fighter (with positive odds), betting $100 can win you that number ($350) assuming the odds shown above.In short, you'll need to put more money down on the favored fighter and less money down on the underdog.


Your daughter wears a drug patch she denies using cocaine but patch reads positive could there be false positives with patches what are the odds?

Have a blood test done ... have the lab check for signs of any illegal drugs. Drug tests can sometimes cause false positives. Cocaine can show as a positive if the person recently took various diet pills, including prescription, or those with ephedrine, or even "energy pills" with ephedrine. Opium can be a false positive if the person recently ate any poppy seed bagels (if the poppy seeds consumed was in an very large amount in a short amount of time.) However, the likelihood of these false positives are a lot more rarer than folks wish they would be. Chances are, that it is truly positive.


Are you pregnant if you had a tubal ligation 5 years ago and are now 14 days late for your period and have taken 2 pregnancy tests and both were negative and you also just got over the flu 1 day ago?

It is unlikely that you are pregnant, but it IS possible. If you are pregnant, the odds are that it is an ectopic (tubal) pregnancy. Sometimes they show positive on home pregnancy tests and sometimes they do not. An ectopic pregnancy cannot be carried to term and cannot result in a viable baby. Without medical intervention, it will burst the tube relatively early in the pregnancy, which can cause you to be in grave danger due to blood loss, etc. You need to contact your doctor without delay and be evaluated to ascertain whether or not you have an ectopic pregnancy. Please don't wait - this could mean your life.
