HelpTest ID PDSUX Drug Screen, Prescription/OTC, Chain of Custody, Urine
Useful For
The qualitative detection and identification of prescription or over-the-counter drugs frequently found in drug overdose or used with a suicidal intent
This test is designed to provide, when possible, the identification of all drugs present.
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.

Clinical Information
This test looks for a broad spectrum of prescription and over-the-counter (OTC) drugs. It is designed to detect drugs that have toxic effects, as well as known antidotes or active therapies that a clinician can initiate to treat the toxic effect. The test is intended to help physicians manage an apparent overdose or intoxicated patient, to determine if a specific set of symptoms might be due to the presence of drugs, or to evaluate a patient who might be abusing these drugs intermittently. The test is not designed to screen for intermittent use of illicit drugs.
Drugs of toxic significance that are not detected by this test are: digoxin, lithium, and many drugs of abuse/illicit drugs, some benzodiazepines, and some opiates.
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.
See Prescription and Over-the-Counter (OTC) Drug Screens in Special Instructions.
