Hair testing is now acknowledged as an effective means for identifying alcohol and drug consumption. Hair captures biomarkers within its fibers, offering an extended timeline of alcohol and drug usage through the growing hair strand. Collected from near the scalp, it can reveal up to a three-month detection period for substances. The collection process for hair is straightforward, less prone to tampering, and convenient for shipment.
A sample measuring 1.5 inches consisting of roughly 200 strands of hair (comparable to a #2 pencil) closest to the scalp will yield 100mg, which is optimal for screening and confirmation tasks. For EtG, additional tests, or for panels exceeding ten, a 150mg specimen is suggested. It is advisable to use a jeweler's scale for weighing the sample. If scalp hair cannot be sourced, an equivalent quantity of body hair is usable. 'Head hair' pertains exclusively to scalp hair, while 'body hair' encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing in the laboratory's system, involving verification of proper sealing and shipment, allocation of a random LAN (Laboratory Accessioning Number), and fulfilling any leftover data entries absent from an electronic chain of custody system.
Screening entails a quick preliminary examination for abused drugs. Despite its cost-efficiency in excluding drug usage for most samples, a positive screening outcome necessitates confirmation for legal admissibility. Samples indicating presumptive positivity during Screening require subsequent confirmation.
Presumptive positives in Screening lead to additional sampling and preparation for Extraction. Drugs are extracted from hair in this phase at much lower levels than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging to implement.
Positive screening results receive Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples undergo prior washing if needed before confirmation. The process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being named "hair follicle tests," the analysis is performed on the hair strand, not the follicle beneath the scalp.
