Hair analysis is increasingly regarded as a robust method for identifying drug and alcohol consumption. The fibers of a growing hair strand capture biomarkers that can reveal a user’s long-term history with these substances. By collecting hair samples near the scalp, one can achieve a detection timeframe of about three months for both alcohol and drugs. This method is straightforward in collection, somewhat resistant to tampering, and convenient for shipping.
A sample measuring 1.5 inches and comprising around 200 hair strands (approximately the thickness of a #2 pencil) closely cropped to the scalp yields 100mg, which is optimal for both screening and confirmation tests. For comprehensive tests such as EtG, additional panels exceeding ten, 150mg is preferred. It's advisable to determine the specimen’s weight using a jeweler’s scale. Should scalp hair be inadequate, an equivalent amount of body hair is acceptable. The term head hair pertains specifically to scalp hair, whereas body hair encompasses all other varieties (like facial and underarm hair).
Process Overview
The drug test laboratory processing involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase where a sample is integrated into a laboratory system. This involves ensuring the sample was appropriately sealed and dispatched, assigning it a unique LAN (Laboratory Accessioning Number), and executing additional data entry when an electronic chain of custody system hasn’t provided all necessary details.
Screening is a preliminary assessment for substances of abuse. Though Screening is a cost-efficient approach for excluding drug use in most samples, a positive outcome mandates further confirmation for legal validity. Samples flagged as presumptively positive during Screening require an additional verification step.
During Extraction, if a sample shows probable positivity at the Screening stage, extra hair is taken from the initial sample and readied for extraction. Hair drug screening extracts drugs from hair at significantly lower concentrations than other methods such as urine or oral fluid, which makes it a more challenging technique to conduct.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive undergo a washing process pre-confirmation, if necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized in accordance with both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
