Hair analysis has emerged as an effective means for detecting substance use involving drugs and alcohol. It provides a comprehensive timeline of alcohol and drug exposure by encasing indicators within the strands of growing hair. When gathered proximal to the scalp, hair can furnish approximately a 3-month detection span for alcohol and other substances. Hair gathering is straightforward, relatively tamper-proof, and convenient for transport.
A sample size of 1.5 inches comprising about 200 strands (roughly equivalent to a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for both screening and validation. For EtG, additional tests, and/or panels exceeding 10, a specimen weight of 150mg is advisable. We advise measuring the sample on a jeweler’s scale. In the absence of scalp hair, a comparable volume of body hair can be collected. When discussing head hair, we specifically mean scalp hair, whilst body hair includes all other hair types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the introductory phase where a sample enters a laboratory's system. This entails ensuring proper sealing and transit of the sample, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not encompassed by an electronic chain of custody system.
Screening constitutes a preliminary swift assessment for drugs of misuse. Although Screening is cost-efficient for excluding substance usage in most specimens, any positive findings must be verified for court acceptability. Samples that return presumptively positive during Screening necessitate further confirmation.
Should a sample test presumptively positive at the Screening juncture, additional hair is extracted from the original sample and prepared for Extraction. In this phase, substances are isolated from hair at substantially lower levels than other testing methods (e.g., urine or oral fluid), making hair drug screening exceedingly complex.
Positive Screening results are validated through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples indicated as presumptive positives undergo washing prior to confirmation as needed. The full laboratory workflow from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
