Hair testing has now emerged as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the growing hair fiber, hair offers a prolonged history of alcohol and drug intake. When taken near the scalp, it provides a potential detection range of up to three months for alcohol and other drugs. Hair collection is easy, tough to tamper with, and straightforward to send.
A 1.5-inch segment consisting of around 200 hair strands (similar to a #2 pencil's thickness) closest to the scalp yields 100mg of hair, considered the optimal sample for both screening and verification. For EtG, additional panels, and/or tests exceeding 10 panels, a specimen of 150mg is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent body hair sample can be taken. "Head hair" refers specifically to scalp hair. "Body hair" denotes other hair types such as facial and axillary.
Process Overview
The key stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails entering the sample into the laboratory's system, verifying secure seal and shipment, assigning a unique LAN (Laboratory Accessioning Number), and handling any additional data not included in an electronic chain of custody.
Screening provides a preliminary check for drugs of abuse. Though cost-effective for ruling out drug use in most samples, a positive screen requires confirmation for legal validity. All samples presumptively positive in Screening need secondary verification.
If screening indicates possible positive results, more hair is extracted for the Extraction phase. Here, drugs are isolated at significantly lower concentrations compared to other methods (e.g., urine, oral fluid), making hair screening a challenging process.
Confirmation of positive screens involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives are cleansed as needed before confirmation. The complete process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
