- Open the specimen container and set the lid aside.
- Ask the test subject to urinate in the cup. The urine level should be above the temperature strip so it will light up. If the urine is too hot or too cold the temperature strip will show no colors. It will be completely black. A temperature strip that shows no colors means the sample is a fake.
- Dip the tabs on the dip card into the urine. Do not dip past the bottom of the device.
- Place the dip card on a clean dry surface and wait 5 minutes. Results can be read after 5 minutes.
- Read the results. The test to the right is positive for opiates (OPI) and benzodiazepines (BENZO). It is negative for meth-amphetamine (METH-AMP), cocaine (COC), and marijuana (THC). The C line is the Control line. It must always be present or the test is invalid. The T line is the Test line and it must completely disappear to indicate a positive test. If there is any line at all left next to T, then it is negative.
- The figure below represents various scenarios you might encounter when reading a test. Some tests have more than one T line on them which means that strip tests for more than one substance.
AMP: Amphetamines, diet pills
BARB (or BAR): Barbiturates, sedatives, hypnotics
BENZO: Benzodiazepines, Valium, Xanax
BZO: Same as BENZO
MDMA: Methylenedioxymethamphetamine, ecstacy
Methadone: Treatment for heroin addicts
MOR: Morphine, pain medications
OXY: Oxycontin, pain medications
PCP: Phencyclidine, angel dust
PPX: Propoxyphene, Darvon (no longer available in the US)
THC: Tetrahydrocannabinol, marijuana, hash
All positive tests must be confirmed by a secondary method in case of a false positive.
