THC Test Strips
Tetrahydrocannabinol is the psychoactive chemical compound found in the marijuana plant. This chemical compound is detectable in human urine specimens for as long as 13 days following ingestion.
As many states move to legalize the medical and recreational use of cannabis, there is an increasing need for rapid, reliable THC test solutions in the workplace, as part of road traffic safety strategies, by court order, and also in rehabilitation where total abstinence is required.
Immunoassay THC urine test strips are rapid results cannabis tests that offer a qualitative ‘positive’ or ‘negative’ result within five minutes of testing a human urine specimen. Reliable within 99% accuracy, THC urine test strips are recommended for random testing programs where there is no margin for error. False-positives are a rare occurrence with THC test strips and there is no reliable way for donors to cheat the test.
Ingesting marijuana in any way has a significant affect on memory, movement, concentration, coordination, thinking, sensory perception, and time perception. Although increasingly used in therapeutic settings for the treatment of pain and other symptoms, these side effects make marijuana use undesirable in workplaces that require adherence to safety or wherein employees are responsible for the safety of others.
Urine tests for marijuana may be used to monitor for drug abuse or compliance with drug use policies. A cannabis test is typically included in standard panel drug tests in the workplace, in governments, and in clinical and rehabilitation settings. THC tests are also used to ensure compliance with court orders and to test impairment following an accident.
THC urine tests are limited in terms of detection times in that they are unable to test for current intoxication. THC metabolites are produced by the liver long after consumption of marijuana, but they remain in the system and can be detected in urine specimens for as long as 13 days.
When THC is metabolized, it forms at least 80 different metabolites that can be detected in a human urine specimen as they are gradually released over the course of up to 13 days. The cutoff concentration for THC and its metabolites is based on SAMHSA standards and is expressed as nanograms per milliliter (ng/ml). Urine tests for marijuana are highly sensitive to any variations in those levels and are predetermined at 50 ng/ml.
A sample urine specimen must be collected from the donor for testing. When the urine specimen is ready for testing, the operator will remove the THC test strip from the protective packaging.
The testing strip may be damaged by extended exposure to light and air. Do not remove the strip until ready to perform the test to ensure the most reliable results. If the testing strip was removed from packaging more than 1 hour prior to testing, the results should not be interpreted.
Do not touch the strip membrane. Bacteria from hands and surfaces may contaminate the testing strip and invalidate results.
Hold the THC test strip where the product name is printed. Carefully place the testing strip membrane into the cup, in a vertical position. Do not immerse the strip past the MAX line on the testing strip.
Allow the strip to absorb as much of the sample as possible, immersing the membrane in the specimen for at least 10 to 15 seconds. You might notice color moving across the strip, but the results cannot be read before five minutes. Do not interpret results after 10 minutes.
If the specimen contains more than the pre-determined cutoff levels, the result is positive. This is indicated by one colored band in the control region and no colored band in the test region. Positive results should be sent to a toxicology laboratory for confirmation.
A negative result is indicated by one colored band in the control region, and one colored band in the test region. A negative result indicates that the specimen does not reach the cutoff levels.
If no colored band appears in the control indicator of the test strip, the result is invalid. The test must be performed again. If the problem persists, you may contact your local distributor.
