Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair captures biomarkers within the strands' fibers, offering a prolonged history of alcohol and other substances. Collected near the scalp, hair can extend up to a 90-day detection window for both alcohol and drugs. It is easy to collect hair, not prone to tampering, and straightforward to transport.
A 1.5-inch lock of approximately 200 hairs (similar to the width of a #2 pencil) nearest the scalp yields 100mg, ideal for both initial and confirmatory tests. For EtG, extra tests, and tests over 10 panels, 150mg is preferable. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair cannot be sourced, an equivalent body hair sample is suitable. Head hair specifically mentions scalp hair, while body hair includes all other hairs (e.g., facial, axillary).
Process Overview
The key steps in lab processing for a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary step where a specimen is registered within a lab’s system: checking the sample’s seal and shipment, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing data absent from the electronic chain of custody.
Screening offers an initial, rapid check for drug usage. Though a cost-efficient method for ruling out drug use in most cases, a positive screening result mandates further confirmation for court admissibility. Samples with presumptive positive results in Screening require secondary verification.
With a presumptive positive in Screening, additional hair is taken from the original sample and readied for Extraction. Here, drugs are separated from hair at much lower levels than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging to execute.
Positive results in screening undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are cleaned before confirmation if necessary. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
