Hair analysis is now recognized as an effective method for uncovering drug and alcohol consumption. Hair strands maintain a prolonged record of alcohol and drug biomarkers within the hair fiber as it grows. When the sample is taken near the scalp, it can offer roughly a 3-month detection timeframe for both alcohol and drugs. Hair collection is uncomplicated, somewhat resistant to tampering, and simple to transport.
A section measuring 1.5 inches of approximately 200 hair strands (the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, supplementary testing, and/or panels exceeding 10, 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. In cases where head hair is unavailable, an equivalent amount of body hair can be taken. Head hair refers strictly to scalp hair, while body hair includes all other forms (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug test outcomes comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is concerned with the initial integration of a sample into laboratory records. This part involves verifying the sample's proper sealing and shipment, generating a unique LAN (Laboratory Accessioning Number), and completing any missing data entry from an electronic chain of custody system.
The Screening phase conduct an initial check for drugs of abuse. Despite being a cost-efficient method for eliminating drug use in most samples, confirmed screening is necessary for court admissibility. Any samples yielding a presumptively positive result during screening demand additional confirmation.
For presumptive positives detected in Screening, additional hair is extracted from the initial sample and readied for the Extraction phase. Here, drugs are separated from hair at lower concentrations compared to methodologies like urine or oral fluid, which makes hair testing more challenging.
GC/MS, GC/MS/MS, or LC/MS/MS methods are used for confirmation of any positive results from screening. All presumptive positive samples undergo necessary washing before confirmation. The entire testing process from Accessioning to Confirmation is assessed against both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
