Lateral flow assays have provided a very useful tool for three decades. Use of the technology is widespread and has proven an inexpensive way to screen, qualitatively and semi-quantitatively, in point-of-care environments. Lateral flow tests are used for medical diagnostics and detect the presence or absence of a target analyte in a sample matrix without the need for additional specialized and expensive medical equipment. The tests are utilized either for at-home-testing, point-of-care testing, or in clinical laboratories, depending on the tests regulatory clearances.
How long is Marijuana detected in the body?
It is difficult to metabolize THC, so Marijuana can remain detectable in the urine for up to several weeks. This compound is stored in the fatty tissues, so chronic users will take longer to remove THC from the body than the occasional user.
What are possible cross reactants for ALFA's THC tests?
Sustiva (efavirenz), an HIV treatment drug, is known to produce metabolites that cross react on many THC assays in the market.
What are the active ingredients in THC?
Tetrahydrocannabinols (THC, Δ-9-THC, Δ-1-THC), are the most active of the principle constituents, as well as the major metabolites, of cannabinoids such as marijuana and hashish.
