Avanti Laboratories offers Medication Monitoring programs tailored to fit your specific practice needs. Every client has unique prescribing habits, which is why we offer customized test panels, rather than a one-size-fits-all panel of tests.
Avanti Laboratories’ enhanced LC-MS/MS technology provides drug specific identification and quantification.
Avanti Laboratories | Urine Toxicology
Qualitative and Quantitative testing of over 90 drugs
What is 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 prior to receiving medicine 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 90 substances at once.
Why Urine Testing?
Help prevent misuse, abuse, and diversion through responsible prescribing
Assist in evaluating a patient prior to controlled medicine therapy
Support substance abuse diagnosis
Monitoring of adherence to treatment plans
Identify undisclosed substances
Protect both patient and practice
How does Urine Toxicology work?
Medical professionals obtain urine samples from patients using clean-catch midstream urine collection. The patient will need to have thoroughly washed 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 Avanti Laboratories.
Our lab uses two types of urine drug screening; Immunoassay and Liquid Chromatography/Mass Spectrometry, or LC/MS. Immunoassay does not measure the substance levels individually. It detects whether the substance is in the system by measuring drug levels in nanograms per milliliter with either a positive or negative result. LC/MS is capable of measuring exact levels of the substance found in the sample.
Who Should Be Tested?
New patients already taking controlled medications
Candidates for controlled medicine therapy
Patients resistant to full evaluation

Patients in substance abuse recovery
Patients displaying aberrant drug behavior
OB patients at risk of harming themselves or child
Patients being monitored on controlled medicine
