InSource Diagnostic ToxLok
InSource Diagnostic launched ToxLok for the verification of urine-based drug tests. ToxLok uses a buccal swab along with the urine sample, and DNA markers from the swab and urine are matched. The test can identify synthetic urine and samples that may be from a friend or relative. ToxLok uses 52 genetic markers to identify each patient and urine sample. Analysis is done by qPCR and MALDI-TOF mass spectrometry.
