    Urine Toxicology

    Urine toxicology is the process of screening urine to determine the type and relative amount of legal and illegal substances a person has consumed. The test is performed to evaluate patients before receiving medical therapy, patients in substance abuse recovery, patients displaying deviant drug behavior, obstetric patients, and patients using controlled medications. Toxicology tests, or tox screens, can detect a specifically targeted substance or up to 80 substances at once.

    Medical providers gather samples from patients using clean-catch midstream urine collection. The patient must wash always their hands before opening the collection cup. Before urinating, the patient will wipe the urethral orifice to ensure the sample is not contaminated with foreign materials. When the sample is collected, the laboratory technician, nurse, or physician will label the sample to be evaluated by Harvest Labs.

    Oral Fluid Toxicology

    Oral fluid toxicology is the process of testing saliva for legal and illegal substances and their metabolites. Oral fluid is excreted from the parotid, submaxillary, and sublingual glands in the mouth. This form of drug screening is the least invasive form of testing. It requires just a simple mouth swab for analysis. Medical professionals prefer to use oral fluid drug testing to evaluate recent drug use in patients.

    Fluid is gathered using a collection swab and sent to Principle Laboratory to be evaluated using cutting-edge technology for initial testing. Our methods allow laboratories to detect recent drug use that urine toxicology alone may miss. If a positive result is detected, our laboratory will perform a confirmation screening using more accurate methods.
