Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. Hair retains a historical record of alcohol and drug use by encasing biomarkers within the structure of the hair shaft as it grows. When gathered near the scalp, hair can offer a detection timeframe of up to roughly three months for alcohol and drugs. Gathering hair is straightforward, relatively resistant to tampering, and convenient to mail.
A hair sample of 1.5 inches consisting of about 200 strands (comparable to a #2 pencil) closest to the scalp will yield 100mg, which is the optimal quantity for screening and verification. For EtG, additional tests, and tests exceeding 10 panels, a specimen of 150mg is suggested. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be obtained. When referring to head hair, we mean scalp hair specifically. Body hair includes any other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is processed into the laboratory’s system. This step includes verifying that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data entry not covered by an electronic chain of custody system.
Screening is a preliminary procedure to quickly check for drug presence. Although cost-efficient, this method requires confirmation of results to be legally admissible. Any samples that test positive initially in Screening necessitate a secondary confirmation.
For any sample testing positive during Screening, more hair is taken from the original specimen for the Extraction phase. Drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug testing methodology.
Confirmation of any positive screening result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positive undergo washing prior to confirmation as needed. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.
