URINE DRUG TESTING

Urine Drug Testing is considered the “gold standard” for drug monitoring, with longer lookback windows and more metabolite visibility for insights into how the medications are being processed in the body. 

We offer state-of-the-art analytical methods for presumptive and definitive urine drug testing of parent drugs and/or metabolites with industry-low detection limits to ensure scientifically sound insight into drug elimination and/or usage over time.

We also offer lightning-fast result turnaround time (TAT) typically 24H for Preliminary and 72H for LCMS results.

THE METHODOLOGIES FOR URINE DRUG TESTING

Enzyme Immunoassay (EIA)

EIA, used for the initial test in the analysis, is designed to detect the presence of multiple drugs and/or drug metabolites. EIA technology involves a specialized enzyme mixed with analyte-specific antibodies. If analyte (drug) is present in the specimen, an active enzyme will form generating a color change that can be measured on a spectrophotometric analyzer. The amount of enzyme formed is proportional to the amount of analyte present in the specimen. EIA provides only a preliminary analytical test result. A more specific alternative chemical method (e.g., UPLC-MS/MS) must be used to obtain a confirmed analytical result.

Enzyme Linked Immunosorbent
Assay (ELISA)

ELISAs are microplate-based assays designed for the detection of either a specific analyte or group of compounds. Unlike an EIA, the ELISA requires a multi-step approach, where the key step requires immobilization of the target antigen. The assay itself can be performed with a number of modifications of the basic procedure including the use of a single or multiple capture antibodies to detect the antigen in a non-competitive manner. Alternatively, the ELISA can be performed as a competitive assay. The latter method is commonly used in commercially available ELISA kits.

Ultra Performance Liquid Chromatography / Tandem Mass
Spectrometry (UPLC-MS/MS)

UPLC-MS/MS is a highly specific method used in the definitive identification of individual drug analytes. Compounds are analyzed by chromatographic separation (UPLC), followed by tandem mass spectrometry (MS/MS). With the addition of the UPLC component, the target compound(s) can be isolated from other sample components using specialized columns and solvents. This “pre-fractionated” sample is then introduced into the mass spectrometer, where it is ionized and fragmented. The detection and identification of specific analyte(s) is made based on the molecular characteristics (i.e., m/z) of both the precursor and product ions. By combining the physical separation capabilities of UPLC with the mass analysis and detection capabilities of tandem mass spectrometry, UPLC-MS/MS serves as the preferred method for the definitive identification and quantification of specific drugs and drug metabolites in biological samples.contact us for more information.
