General Laboratory Testing Methods

Urine Test Methodology

Urine testing may include a two-part process—screening and confirmation. we perform initial screening through immunoassay, a technique for analyzing and measuring drugs of abuse in urine. If the specimen initially tests positive, a confirmation test is performed before the laboratory reports the result.

We confirm the presence of drugs using analytical methods that combine chromatographic separation with mass spectrometric identification. These types of methods include gas chromatography/mass spectrometry (GC-MS or GC-MS/MS) and liquid chromatography/mass spectrometry (LC-MS or LC-MS/MS). These confirmation tests can identify compounds by their retention times and molecular structure and are recognized by courts and scientists as the most definitive methods to verify a drug of abuse.

Oral Fluid Test Methodology

Utilizing both immunoassay and liquid chromatography/tandem mass spectrometry (LC-MS/MS) technology, we provide customers with a definitive analysis of a wide array of substances of abuse, in an easy-to-read report format.

While the testing process is two-part as it is with urine testing (screening and confirmation), the amount of drug or drug metabolite present in oral fluid is much lower than that present in urine. Clients using oral fluid testing can still expect the same level of quality and service guiding our urine-based testing operations.
