Old unrefrigerated urine is generally not suitable for testing due to the potential for bacterial growth and chemical changes that occur over time. These factors can compromise the accuracy of the test results. For reliable outcomes, fresh or properly preserved urine samples should be used.

No. When given a drug test you will be watched to make sure you don't cheat. The chemicals used will be able to tell that the urine is old as well as what drugs you have taken. If they have any doubt with a urine test they can test your hair and that will show what drugs you have had.

What is the correct time of day to take a pregnancy test?

If you are testing very early on, I would suggest you kick it old school and go with first morning urine. Many of the latest pregnancy tests no longer require this but morning urine will still contain the greatest amount of HCG if it is present. It truly depends on how early you are doing the testing. If that isn't the case, well then, go for it...and I hope you get the desired result.

Is drug testing a three year old considered abuse?

It really depends on the situation. If you think someone is giving the child drugs against their will, then no it's not abuse, and further more I wouldn't think drug testing children would be any kind of abuse, cause you are not harming them as long as it is urine screening. Thanks smiley9086
