The use of hair testing has emerged as an effective way to identify drug and alcohol consumption. Hair retains biomarkers within its strands, offering a long-term history of substance use. When collected near the scalp, hair offers an approximate three-month detection period for alcohol and drugs. Collection is straightforward, tough to tamper with, and easy to transport.
A sample of 1.5 inches, containing around 200 hair strands (similar in size to a #2 pencil) from the scalp will yield 100mg, which is optimal for screening and verification. For EtG, additional testing, or panels beyond 10, a 150mg sample is advised. The use of a jeweler's scale for weighing is suggested. If head hair is not available, equivalent body hair can be used. "Head hair" signifies only scalp hair, while "body hair" covers all other types (facial, axillary, etc.).
Process Overview
The laboratory procedure for handling a drug test result encompasses four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the sample's entry into the laboratory system. This phase includes ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening involves an initial check for substances. While this offers a cost-efficient method to negate drug use for most samples, results that are positive need confirmation to be legally valid. Presumptive positive samples in Screening need further confirmation.
If Screening indicates a presumptive positive, additional hair from the original sample is used for Extraction. This phase extracts drugs at a lower concentration than other methods (e.g., urine or oral fluid), distinguishing hair drug testing as the most challenging method.
Confirmation for positive Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing if required before confirmation. The complete process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being labeled as "hair follicle tests", the actual analysis occurs on the hair strand rather than the follicle beneath the scalp.
