Quantitative Urine Drug Confirmation Testing


Andor Lab’s Pain Management Urine Confirmation Test Program includes drugs and metabolites from 17 categories. All Confirmation Testing is performed using Liquid Chromatography and Atmospheric Pressure Ionization Tandem Mass Spectrometry (LC–API MS/MS) technology. LC-MS/MS is considered the “gold standard” for identification of drugs in biological specimens and provides the highest level of certainty in drug testing.

To increase confidence in test results, Andor Labs chooses to confirm both intact drug and a major metabolite in many cases.

The list below identifies the specific drugs/metabolites included currently in each Andor Confirmation test category. Please inquire about a drug or metabolite that may not be on the current list.

Amphetamines/ MDMA Amphetamine, Methamphetamine, Methylenedioxymethamphetamine (MDMA), Methylene dioxyamphetamine (MDA), Methylenedioxyethylamphetamine (MDEA)
Barbiturates Amobarbital, Butalbital, Pentobarbital, Phenobarbital, Secobarbital
Benzodiazepines Alprazolam, Hydroxyalprazolam, 7-Aminoclonazepem, Diazepam, Lorazepam, Nordiazepam, Oxazepam, Temazepam
Buprenorphine Buprenorphine, Norbuprenorphine
Cannabinoids 11-nor-Δ9-Tetrahydrocannabinol-9-carboxylic acid (THCA)
Carisoprodol Carisoprodol, Meprobamate
Cocaine Benzoylecgonine, Cocaethylene, Cocaine
Ethanol Ethyl Glucuronide, Ethyl Sulfate
Fentanyl Fentanyl, Norfentanyl
Heroin Metabolite 6-Monoacetylmorphine (6-MAM)
Meperidine Meperidine, Normeperidine
Methadone Methadone, Ethylidine-dimethyl-diphenylpyrrolidine (EDDP)
Opiates/ Major Opioids* Morphine, Codeine, Hydrocodone, Hydromorphone, Oxycodone, Oxymorphone
Phencyclidine Phencyclidine (PCP)
Propoxyphene Propoxyphene, Norpropoxyphene
Tapentadol Tapentadol
Tramadol Tramadol, O-Desmethyltramadol

* Note: Oxycodone is listed often a separate category because it is a separate screening test from Opiates. Hydrocodone, Hydromorphone, Oxycodone and Oxymorphone are not Opiates, they are Opioids. They are all included in Andor Labs Opiates/Major Opioids Confirmation test category.

Specimen Shipping/ Pickup

Andor Labs can provide a supply of collection cups and shipping supplies to any client facility. Overnight shipping via FedEx is usually the most efficient mode of transportation for specimens from the client facility to Andor Labs. Within a 50-mile radius of our laboratory we can provide daily pickup via our courier service.

Andor Labs will supply requistion forms and shipping supplies (if requested) to any client facility.

Recommended Collection Cup

Andor Labs recommends the CLIA-waived and FDA-approved OneScreen Multi-Drug Test Cups which generate results within minutes of activation. CLIAS waived test cups are a convenient tool for medical staff to use as a preliminary measure of drug exposure.

Information on the OneScreen Multi-Drug Test Cups can be found on the American Screening Corporation website link below:

Validity and Semi-Quantitative Urine Drug Screening

Andor Labs subjects all urine specimens to Validity Testing prior to any further testing. Validity Testing determines if the specimen is consistent with human urine (i.e., not adulterated) and ensures high integrity of confirmation test results.

pH A measure of acidity/alkalinity
Specific Gravity A measure of salts and other dissolved compounds
Creatinine A measure of muscle breakdown and related to kidney function
Nitrites A test for the presence of potassium or sodium nitrite added to urine to foil a drug test
Oxidants A test for the presence of bleach, hydrogen peroxide or other oxidizing agent added to urine to foil a drug test

Andor Labs offers semi-quantitative urine drug screening with use of an Olympus Analyzer from Beckman Coulter. These tests can replace or be an adjunct to initial qualitative drug screening performed in the clinic with use of a collection cup. Andor can customize a list for each client facility based on the clinical practice requirements upon request.
