Why does the dot disappear when the test strip is at a certain distance from the eye?

This is due to having a natural blind spot in your eye where your "rods and cones" meet at your optic nerve. This spot can be found by: closing one eye and moving one finger horizontally, approx 5 - 6 inches from your face and 1 - 2 1/2 inches down in a side to side motion.

Do drug test results take longer if they are positive?
No. A drug test is a colored strip dipped in the urine. The person administrating the test has to let the strip sit in the cup or urine for about 15-30 seconds to ensure an accurate result. If the strip had a certain code, or color on it, then it will show either positive or negative. Either way it takes relatively the same length of time.

If you drop your pregnancy test and it makes one of the lines which was forming go away is it still considered a positive result?
Dropping the test changes nothing and does not make lines appear or disappear. The test is a simple chemical reaction that occurs when urine is applied to the test strip inside the pregnancy test. You cannot shake the sweet taste off an orange, you cannot drop a banana and have the vitamins fall out/off, and you cannot shake the lines on or off a pregnancy test.
