About 12 Panel Drug Test (Drugs of Abuse Testing), Hair in Weslaco
The 12 Panel Drug Test, Hair analyzes a hair sample to identify recent or past exposure to a standard group of drugs of abuse.
Hair testing works by detecting drug compounds and their metabolites that become incorporated into the hair shaft as it grows. Because hair grows at a predictable rate, a sample can provide a historical record of exposure. The 12-panel format usually includes common classes such as amphetamines, cocaine, opiates, phencyclidine, and cannabinoids, though the exact list can vary by laboratory.
The specimen is typically collected by cutting a small amount of hair close to the scalp, most often from the back of the head. The sample does not require special timing relative to recent use, and collection is generally quick and non-invasive. Results are reported as negative or positive for each drug class, with positive screens sometimes followed by confirmatory testing.
Turnaround for this test is generally 1-3 business days after the specimen reaches the laboratory. Preparation is minimal; follow the lab's instructions. Because hair can be affected by external contamination, some laboratories provide specific guidance on washing and collection to support accurate results.
