Blood testing is most commonly used in DUI determinations, therapeutic monitoring and in situations where blood is the only sample available. Our BloodStat^SM assay identifies usage over a one-day to two-day period, and has the ability to provide under the influence interpretation. USDTL recently released a new direct alcohol biomarker assay, PEthStat^®, as a stand-alone or add-on assay for alcohol detection. An individual consuming one drink per day for six days to seven days a week will produce a positive phosphatidylethanol (PEth) result.

BloodStat^SM is available in 5-, 7- and 9-drug panels with the optional PEth and ethanol add-on assays for any profile.

Drug panels

5-drug panel: amphetamines, cannabinoids, cocaine, opiates, phencyclidine (PCP)

7-drug panel: 5-drugs plus benzodiazepines and barbiturates
