Is urine temperature a adequate way to determine a positive drug screen for preemployment?

If a cold urine sample is submitted (should be warm if it is fresh), it may be rejected as possibly from someone else. So, while it is not "positive" for drugs, it has "failed" part of the test.

What is the temperature coefficient of an extrinsic semiconductor is?
positive
Is an absolute temperature scale always positive?
Yes, it is always positive. 0 K is the lowest temperature there can be.
How do you determine the number of electrons in a positive ion?
impossible.
What is the temperature of a pink dolphin?
3.0000003.3c and i am positive
What is the temperature coefficient of extrinsic semiconductor?
positive
Why temperature coefficient of copper is positive?
yes
What is the coldest temperature with positive and negative?
-1
What is the temperature at 90000 feet?
Negative or positive?
Why do conductor have a positive coefficent?
You mean positive temperature coefficient? Yes conductors as they get heated then due to the nucleii vibrating with greater amplitude would have a grip over the moving electrons and so the resistivity increases with the increase in temperature. Hence positive temperature coefficient.
Why is positive feedback helpful in blood clotting but unsuitable for the regulation of body temperature?
Positive feedback accelerates the clotting process, but temperature would rise out of control.
What is the difference between positive and negative temperature coefficient of resistance?
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
Is fifteen degrees positive or negative?
This is a positive temperature on the Celsius scale and negative on the other scales.
