The emergence of hair testing is recognized as an effective means to detect drug and alcohol consumption. Hair can offer an extended timeline of alcohol and drug use through biomarkers embedded within its growing strand. Collecting hair near the scalp can reveal a detection period for alcohol and drug consumption of up to roughly three months. The process of collecting strands is straightforward, complicating attempts at tampering and facilitating simple shipping.
A sample from about 200 hair strands, measuring 1.5 inches near the scalp, yields 100mg of hair—the optimal quantity for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, 150mg of sample hair is advisable. Using a jeweler's scale is encouraged for weighing the sample. In the absence of scalp hair, a comparable measure of body hair is acceptable. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
There are four key stages in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample within a laboratory's framework. It verifies proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and finalizes any further data entry missing from an electronic custody chain system.
Screening acts as a preliminary assessment for substance abuse. Though Screening offers an economical approach to indicate drug use for most samples, positive results demand official confirmation for legal admissibility. Samples with presumptive positives from Screening must undergo additional verification.
For presumptively positive samples in the Screening stage, more hair is extracted from the primary sample for preparation in Extraction. During this phase, drugs within hair are extracted at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening amongst the most complex methodological practices.
Confirmed positive results from Screening are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives are thoroughly cleansed before confirmation, as necessary. The entire lab process, spanning from Accessioning to Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests," the procedure actually assesses hair strands rather than the follicles beneath the scalp.
