DOA Drug Screen Test Kits

One-Step DOA Drug Test Devices

DOA Drug Screen tests, also called one-step DOA drug tests, employ unique monoclonal antibodies to selectively identify specific drugs of abuse (DOA) and the corresponding metabolites in urine samples with a high degree of sensitivity and specificity. DOA rapid tests are lateral flow, qualitative quick check devices based on the drug-competitive inhibition immunoassay. When testing with a rapid drug urine test, if the urine samples contain the drug and its metabolites the drug screen test device intended to test, they will be captured by the immobilized antibody compounds at the test line (T) region. And when the concentration of the drug of abuse and its metabolites reach the cut-off level of the testing kit, the color developing chemicals in the membrane of the testing strip will float away because there is no sites for them to bind to. So no color develops at the testing line, indicating a positive result. On the contrary, if there is no drug in the urine, the color developing chemicals will bind to the sites on the test line region. So two lines at the result window indicate a negative result.

At present, Atlas Link Biotech is supplying 12 drug of abuse testing devices (test strip or test cassette), which test AMP, BAR, BZO, COC, MDMA, mAMP (MET), MOR (MOP), MTD, OPI, PCP, TCA and THC respectively. At the same time, DOA test panels are widely used for urine sample screening.

For all our DOA screening test devices, the cut off concentration for specific drug of abuse (DOA) and its metabolites has been developed at the concentration standards set by NIDA (the National Institute on Drug Abuse of USA) for the qualitative detection of corresponding drugs in human urine sepcimens.

DOA urine screening tests are highly sensitive and specific;
One Step DOA testing results are read visually without the need for other instrumentation;
No extra reagent is needed for these tests;
DOA testing kits are used to screen urine specimens for the presence of corresponding drug of abuse and its metabolites;
DOA testing devices are available in strip, cassette and multi-drug panel styles;
2, 4, 5, 6 and 10 multi-drug test panels (DOA 602, DOA 604, DOA 605, DOA 606 and DOA 610 Drug Test ) are available (Combinations subject to customers’ selection).
