JNCMED™ Multi-drug Rapid Test Kit (Urine) Cut-off
What are drug test cut-off levels?
Drug test detects the presence of drugs and drug metabolites using cutoff levels to determine whether a specimen tests positive or negative for the use of a specific drug.
JNCMED™ Multi-drug Rapid Test Kit
JNCMED™ Multi-drug Rapid Test Kit (Urine) is a rapid visual immunoassay for the qualitative detection of drugs of abuse in human urine specimens. The test kit detect OPI, MOP, BZO, MET, MDMA, PCP, THC, BAR, OXY, TCA, TML, PPX, AMP, MTD, COC, KET, K2, BUP, COT, FYL in urine qualitatively.

JNCMED™ Multi-drug Rapid Test Kit Test Principle
Multi-Drug Strips: This kit uses specific antigen-antibody reaction, combining Gold Immunochromatography Assay experiment, highly specific and sensitive competition method to detect OPI, MOP, BZO, MET, MDMA, PCP, THC, BAR, OXY, TCA, TML, PPX, AMP, MTD, COC, KET, K2, BUP, COT, FYL in urine.
When testing, urine moving forward under the action of chromatography. If the concentration of the analyte in urine is below the cut-off level, colloidal gold antibodies can not be combined with the analyte in the urine completely, and the rest of colloidal gold antibodies will be captured by the conjugated antigen on the NC membrane, appearing a visible red precipitate line (test line T). If the concentration of the analyte in urine is higher than the cut-off level, the analyte in urine can combine all of colloidal gold antibodies, thus no colloidal gold antibodies can combine with the antigen conjugated on the NC membrane, so no red line appeared in the test area(T). Whether the analyte exists in the urine or not, a red line (control line C) will always appear in the control area (C) to serve as a procedure control.
