5 panel Hair drug test
The HAIR-5 test refers to a 5-panel drug test conducted using hair samples. Hair drug testing is highly effective for detecting drug use over an extended period, typically up to 90 days, depending on hair length and growth rate.
Description of the HAIR-5 Test:
HAIR: Indicates the testing is performed on a hair sample. Hair tests detect drugs embedded in the hair shaft, offering a longer detection window than urine or saliva tests.
5: Refers to the 5-panel drug test, which typically screens for the following substances:
Marijuana (THC): Cannabis metabolites
Cocaine: Including crack
Amphetamines: Includes methamphetamine and MDMA (ecstasy)
Opiates: Includes codeine, morphine, and heroin
Phencyclidine (PCP): A hallucinogen
Key Features:
Detection Window:
Up to 90 days, depending on the hair length (approximately 0.5 inches of hair represents 30 days of growth).
Sample Collection:
A small sample of hair is typically cut close to the scalp (about 1.5 inches for a 90-day history).
Benefits:
Difficult to tamper with.
Longer detection window compared to urine or saliva tests.
Limitations:
Cannot detect very recent drug use (within the last 5–10 days) because drugs take time to incorporate into hair.
