Hair testing is recognized as a robust method for identifying drug and alcohol usage. Hair offers an extended history of alcohol and other substances by entrapping biomarkers within its strands during growth. When hair samples are collected close to the scalp, they provide an estimated 3-month detection span for alcohol and other drugs. Collecting hair is straightforward, tough to tamper with, and simple to transport.
A 1.5-inch section containing around 200 hair strands (about the same size as a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect quantity for both screening and verification. For EtG, add-ons, or tests exceeding 10 panels, a sample of 150mg is advised. We suggest weighing the sample using a precision scale. If scalp hair is not obtainable, a similar amount of body hair can be used. By head hair, we mean scalp hair strictly. By body hair, we refer to hair from other areas (facial, underarm, etc.).
Process Overview
The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample within the laboratory’s system. This includes ensuring the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody system.
Screening involves a preliminary assessment for substances of abuse. While Screening is a cost-effective means to rule out drug usage for most samples, a positive screen must be confirmed to be valid in legal settings. Any sample that tests presumptively positive in Screening requires a secondary confirmation.
Should a sample test presumptively positive during Screening, more hair is retrieved from the initial sample for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is among the most challenging methodologies to carry out.
Confirmation of a positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair label and the ISO / IEC 17025 accreditation standards.
