Excerpt: A drug test is a technical analysis of a biological specimen - for example urine, hair, blood, sweat, or oral fluid / saliva - to determine the presence or absence of specified parent drugs or their metabolites. Major uses of drug testing are to detect the presence of performance enhancing steroids in sport or for drugs prohibited by laws, such as cannabis, cocaine and heroin. A "10-panel urine screen" consists of the following: The following chart from LabCorp gives approximate detection periods for each substance by test type. The detection windows depend upon multiple factors-drug class, amount and frequency of use, metabolic rate, body mass, age, overall health, and urine pH. For ease of use, the detection times of metabolites have been incorporated into each parent drug. For example, heroin and cocaine can only be detected for a few hours after use, but their metabolites can be detected for several days in urine. In this type of situation, we will report the (longer) detection times of the metabolites. Oral fluid or saliva testing results for the most part mimic that of blood. The only exceptions are THC (tetrahyrocannabinol) and benzodiazepines. Oral fluid will likely detect THC from ingestion up to a maximum period of 6-12 hours. This continues to cause difficulty in oral fluid detection of THC and benzodiazepines. Rapid oral fluid products are not approved for use in workplace drug testing programs and are not FDA cleared. Using rapid oral fluid drug tests in the workplace is prohibited in only: Drug Screens are reported as PASS, or FAIL with urine reported invalid or adulterated. When an employer requests a drug test from an employee, or a physician requests a drug test from a patient, the employee or patient is typically instructed to go to a collection site or their home. The urine sample goes through a specified 'chain of custody' to ensure that it is not tampered with or invalidated through lab or employee error. The patient or employee's urine is colle
