Drug test kit colors, I drug like kit test that colors crossdresser
Urine tests are deemed accurate for detecting a wide variety of the most abused street drugs. The way to find which kind of drug is being abused is indicated in a key, a color-coded graphic that connects the colors on the urine test strip to the type of drug being used. A urine testing kit comes with slender test strips protected in foil, a color-coded chart or table, and a vial, of course.

The process works by exposing the urine sample to special chemical reagents within the test strip in a specific order and at a specific speed.
When the First Check Test Lid is secured to the top of the cup and the cup is tilted onto its legs, the urine in the cup comes into contact with the First Check test strips on the Test Lid. The absorbent material of each test strip carries the urine sample across the strip at a specific speed. First, the urine sample encounters drug-specific antibodies that only react to the specific drug or drug metabolites being tested for.
These drug-specific antibodies are permanently bound to large, colored particles. If the urine sample does not contain the specific drug or drug metabolites being tested for, the colored particles with the antibodies will flow up the test strip and be captured at a special location on the strip, forming a red or pink Drug Line.
When the colored Drug Line appearsthe test is Negative for the drug being tested for.
If the urine sample does contain the specific drug or drug metabolites being tested for, the colored particles with the antibodies will flow past the special location on the strip and no Drug Line will form. When no colored Drug Line appearsthis indicates a Preliminary Positive Result for the drug being tested for.
Finally, the sample reaches the control location near the top of the test strip where some of the colored particles are captured to form a red or pink Control Line. A visible Control Line indicates that flow through the strip was successful and the test is working properly. We recommend all preliminary positive be sent to the laboratory for free confidential confirmatory testing.
