7 Soap in Urine
One of the biggest complaints you hear is when people get a “false positive” result from test contamination. Instructions for the test always state to pee directly on the test strip or use a clean container to collect urine. If you use a container that has been washed with soap and not rinsed completely, detergents and soap may alter the test. Try peeing in a cup and putting a drop of liquid soap in your urine. Then dip the stick and let it rest a few minutes.
