Hair tests are now regarded as an effective method for identifying drug and alcohol usage. Hair records a comprehensive history of substance use by capturing biomarkers within the fibers of its growing strands. Sampling hair close to the scalp allows for up to a three-month timeframe to detect alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient for shipping.
Taking a 1.5-inch segment of roughly 200 hair strands (around the thickness of a #2 pencil) from near the scalp yields 100mg, ideal for analysis and confirmation. For EtG, additional tests, and those exceeding 10 panels, a 150mg specimen is advisable. It's suggested to measure the specimen using a jeweler’s scale. If scalp hair is missing, a comparable quantity of body hair is an alternative. By head hair, we mean solely scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result comprises four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary processing of a specimen into a lab’s system. It involves ensuring the sample was correctly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and performing any subsequent data entry absent in an electronic chain of custody system.
Screening serves as an initial, swift assessment for substances. Though Screening is a cost-efficient method to negate drug use in most samples, results positive during screening require corroboration to be valid in judicial settings, necessitating secondary confirmation.
Should a specimen show presumed positivity at the Screening phase, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations than other approaches (e.g., urine or oral fluid), making hair drug tests the most complex to conduct.
Confirmation of any promising screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing before confirmation when required. The complete lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair guideline and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though often dubbed "hair follicle tests," the test actually examines the hair strand rather than the follicle beneath the scalp.
