Order 12 Panel Drug Test (Drugs of Abuse Testing), HairThe 12-panel hair drug test is a laboratory method used to detect recent drug exposure across a broad set of substance categories.

About 12 Panel Drug Test (Drugs of Abuse Testing), Hair in Daly City
Hair drug testing relies on the deposition of parent drugs and metabolites into the hair follicle as it grows.
As hair forms in the follicle, circulating substances can be incorporated into the keratin structure. Because hair grows at a relatively steady rate, a sample taken from close to the scalp can reflect exposure over a period of weeks to months, depending on the length of the specimen collected.
A 12-panel test typically screens for amphetamines, methamphetamines, cocaine, opiates, marijuana, PCP, benzodiazepines, barbiturates, methadone, propoxyphene, ecstasy, and oxycodone. The exact list of analytes can vary by laboratory, so the panel configuration should be confirmed with the testing provider.
Collection is generally straightforward and non-invasive. A small amount of hair is cut close to the scalp, and the sample is sent to a laboratory for immunoassay screening with confirmation by mass spectrometry when a presumptive positive result is identified. Turnaround is commonly reported as one to three business days after the specimen reaches the lab.
