Instant DRUG Testing PLUSPhysicians require toxicology services in pain management, chemical dependency, drug abuse and mental health screens. Often, this testing is used to answer clinical concerns such as medication adherence, diagnosis or confirmation of drug abuse or addiction, an adjunct to self-report of drug use or drug history and to reinforce healthy behavioral changes as a requirement for continued treatment.
Lab Test Diagnosticsis one of the first private (local) clinical laboratories to offer LCMS/MS testing. The LCMS/MS is a technique that incorporates the separation power of Liquid Chromatography (LC) and the unique and specific identification of analyte mass using tandem mass detectors (MS/MS). This sophisticated and high complexity method is available to providers for confirmation of drugs of abuse as well as drugs commonly used in pain management and drug dependency programs. This type of advanced confirmation instrumentation is often only available to clients through large reference laboratories. The acquisition of the LCMS/MS technology shows the vision and commitment of Lab Test Diagnostics as a provider of quality laboratory testing.
DRUG ScreeningThe most commonly used urine screens for drugs are immunoassay (IA) and Point of Care Tests (POCT). Commonly prescribed medications and over-the-counter drugs can potentially cause false positive urine drug test results from these methods. Both of these screening methods are services available at Lab Test Diagnostics. Also Lab Test Diagnostics offer comprehensive drug screens by LCMS/MS.
TestingIn addition to urine screens for drugs, Lab Test Diagnostics provides urine validation testing. Validity testing includes checks for temperature, pH, creatinine, and specific gravity. These screening methods need to be confirmed using more specific methods such as Liquid Chromatography/Tandem Mass Spectrometry (LCMS/MS).
