Hair analysis has become recognized as an effective method for identifying drug and alcohol use. Hair serves as a chronological record of substances by capturing biomarkers within the developing hair fibers. When obtained near the scalp, hair offers a detection timeframe of up to about three months for alcohol and other substances. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.
A 1.5-inch section consisting of roughly 200 hair strands (approximately the width of a #2 pencil) nearest the scalp yields 100mg, which is the optimal sample size for testing and verification. For EtG, supplemental tests, and panels exceeding 10, 150mg of the sample is advised. It's suggested to use a jeweler's scale for precise weight measurement. If scalp hair cannot be acquired, an equivalent amount of body hair can be utilized. "Head hair" refers exclusively to scalp hair. "Body hair" includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into a lab’s system, confirming the sample's seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and finishing any additional data input absent in an electronic chain of custody.
Screening entails an initial rapid inspection for illicit drugs. While Screening is cost-effective for excluding drug use in most samples, a positive screen demands validation to be courtroom-admissible. Samples with presumptive positive results from Screening need further verification.
If Screening suggests a positive result, additional hair is taken from the original sample for Extraction preparation. During this phase, substances are extracted from hair in far lower concentrations than in other techniques (e.g., urine or oral fluid), making hair drug testing the most challenging to execute.
Confirmation of any positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as necessary. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the evaluation is conducted on the hair strand itself, not the follicle below the scalp.
