Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. By securing biomarkers within the hair's expanding fiber, hair captures a long-term chronology of substance usage. When sourced near the scalp, hair can reveal a roughly 3-month detection span for alcohol and drugs. Collection is straightforward, alteration is challenging, and transport is uncomplicated.
A sample measuring 1.5 inches long, comprising approximately 200 hair strands (comparable to a #2 pencil), from the scalp will weigh 100mg, which is the optimal sample size for assessment and verification. For EtG, additional tests, and/or examinations beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair isn’t available, an equivalent quantity of body hair may be gathered. Reference to head hair pertains to scalp hair exclusively. All other hair types (facial, axillary, etc.) are considered as body hair.
Process Overview
The principal stages in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially processed into a lab's system. This step includes ensuring proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry omitted by an electronic chain of custody framework.
Screening entails an initial rapid assessment for substance misuse. Although Screening offers a cost-efficient method to rule out drug usage for most samples, a positive result requires confirmation to be accepted in judicial settings. Any samples indicating presumptive positivity in Screening require a subsequent confirmation.
Should a sample indicate presumptive positivity during Screening, additional hair is derived from the initial sample for Extraction. This phase involves extracting substances from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), underscoring why hair drug screening is notably complex.
Confirming any positive screening results occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing prior to confirmation when necessary. The complete lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
