Testing Algorithm
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
Testing begins with screening tests for alcohol and drugs of abuse. Positives are confirmed and quantitated by definitive methods (gas chromatography with flame ionization detector for ethanol; gas chromatography mass spectrometry for barbiturates, cocaine and metabolites, methadone, and phencyclidine) at an additional charge. Amphetamines, benzodiazepines, opiates, and tetrahydrocannabinol metabolite that screen positive will be quantified with liquid chromatography tandem mass spectrometry at an additional charge.
Adulterants testing will be performed on all chain-of-custody urine samples as per regulatory requirements.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
This assay was designed to test for and confirm the following drugs, by either gas chromatography-mass spectrometry (GC-MS), gas chromatography flame ionization detection (GC-FID), or liquid chromatography tandem mass spectrometry (LC-MS/MS):
-Amphetamines
-Barbiturates
-Benzodiazepines
-Cocaine
-Ethanol
-Opiates
-Methadone
-Phencyclidine
-Tetrahydrocannabinol
This test uses the simple screening technique which involves immunoassay testing for drugs by class. All positive immunoassay screening results will be confirmed by the definitive assay available and is described in each individual reflex test (eg, AMPHU / Amphetamines Confirmation, Random, Urine). All positive screening results are confirmed by either GC-MS, GC-FID, or LC-MS/MS and quantitated before a positive result is reported.
Chain of custody is a record of the disposition of a specimen to document who collected it, who handled it, and who performed the analysis. When a specimen is submitted in this manner, analysis will be performed in such a way that it will withstand regular court scrutiny. Chain of custody is required whenever the results of testing could be used in a court of law. Its purpose is to protect the rights of the individual contributing the specimen by demonstrating that it was under the control of personnel involved with testing the specimen at all times; this control implies that the opportunity for specimen tampering would be limited.

Interpretation
Provides information to assist in interpretation of the test results
A positive result indicates that the patient has used the drugs detected in the recent past. For more information, see individual tests (eg, AMPHX / Amphetamines Confirmation, Chain of Custody, Random, Urine).
For information about drug testing, including estimated detection times, see Drug Class Testing.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
The test does not screen for drug classes other than those listed above. More comprehensive screening is available using the serum or urine drug screens (DSSX / Drug Screen, Prescription/Over the Counter, Chain of Custody, Serum or PDSUX / Drug Screen, Prescription/Over the Counter, Chain of Custody, Urine).

Method Description
Describes how the test is performed and provides a method-specific reference
The amphetamines, barbiturates, benzodiazepines, cocaine, methadone metabolite, opiates, phencyclidine, and tetrahydrocannabinol metabolite assays are based on the kinetic interaction of microparticles in a solution (KIMS) as measured by changes in light transmission. In the absence of sample drug, soluble drug conjugates bind to antibody-bound microparticles, causing the formation of particle aggregates. As the aggregation reaction proceeds in the absence of sample drug, the absorbance increases. When a urine sample contains the drug in question, this drug competes with the drug derivative conjugate for microparticle-bound antibody. Antibody bound to sample drug is no longer available to promote particle aggregation, and subsequent particle lattice formation is inhibited. The presence of sample drug diminishes the increasing absorbance in proportion to the concentration of drug in the sample. Sample drug content is determined relative to the value obtained for a known cutoff concentration of drug.(Package inserts: EDDP Specific Urine Enzyme Immunoassay. Immunalysis; 09/2018; AMPS2 cobas.
