The examination of hair has gained recognition as an effective means for identifying drug and alcohol consumption. Hair can chronicle an extended history of alcohol and other substances due to the entrapment of biomarkers within the hair fibers as they grow. When hair is clipped near the scalp, it can offer a detection timeframe of up to around three months for alcohol and other drugs. Hair is easy to gather, somewhat resistant to tampering, and convenient to transport.
An optimal sample for testing and verification is a 1.5-inch segment composed of roughly 200 hair strands (approximately the thickness of a #2 pencil), taken nearest to the scalp, yielding 100mg of hair. For EtG testing, additional requests, and/or panels exceeding ten, 150mg of the material is advisable. We suggest measuring the sample using a jeweler’s scale. If head hair isn't accessible, an equivalent volume of body hair may be gathered. When mentioning head hair, we imply only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test outcome involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into the laboratory’s system. This process covers confirming the correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry that an electronic chain of custody system doesn’t provide.
Screening represents a preliminary rapid assessment for addictive substances. Although Screening is a cost-efficient approach to eliminate drug use in most samples, a positive screen must be validated for legal acceptance. Samples that test presumptively positive in Screening must undergo additional confirmation.
For samples that appear presumptively positive during Screening, more hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging.
Positive screening results are substantiated through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples are cleansed as necessary. The complete laboratory process from Accessioning to Confirmation is reviewed in accordance with both the CAP (College of American Pathologists) Hair designation and the accreditation under ISO / IEC 17025 standards.
