TCA Urine Screen Test Devices
TCA Drug Urine Screen Test Cassette and Strip
TCA Urine Screen Tests are a lateral flow chromatographic immunoassay. One-step TCA tests utilize a monoclonal antibody to selectively detect elevated levels of Tricyclic Antidepressants and its metabolites in human urine samples. NOVAtest™ TCA Drug cards and strips can be used as TCA self-test devices, which yields a positive result when concentration of Tricyclic Antidepressants in urine exceeds 1000 ng/mL. Atlas Link Biotech would like to supply CE Marked TCA Urine Test in bulk and at competitive price.
TCA Drug Tests are an immunoassay based on the principle of competitive binding. With TCA Drug Rapid Test, an Tricyclic Antidepressants-positive urine specimen (TCA conc. >1,000ng/mL) will not generate a colored line in the test region because of drug competition, while a TCA-negative urine specimen or a specimen containing a TCA drug concentration less than the cut-off will generate a line in the test region.
