What is Definitive UDT?
Definitive UDT is used when medically necessary to identify specific medications, illicit substances and metabolites. Definitive testing is performed at Millennium Health with liquid chromatography-tandem mass spectrometry (LC-MS/MS) and provides quantitative results (numerical concentration levels of drug in the sample). Definitive UDT may also be referred to as “confirmation” testing.
Definitive UDT may be reasonable and necessary based on patient specific indications, including historical use, medication response and clinical assessment, when accurate results are necessary to make clinical decisions.
