Hair analysis is regarded as an effective method for identifying alcohol and drug consumption. Hair captures a chronological record of substance use by embedding biomarkers in the strands of the hair as it grows. When clipped near the scalp, hair offers up to a three-month time frame for detecting alcohol and drugs. Collecting hair is straightforward, tough to tamper with, and simple to transport.
A 1.5-inch segment containing roughly 200 strands of hair (comparable to the diameter of a #2 pencil) nearest to the scalp supplies 100mg of hair, which is the preferred sample size for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, it is advisable to use 150mg of the sample. We suggest weighing the hair on a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair might be used. References to head hair pertain strictly to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The main components of laboratory processing in a drug test involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample within a lab's system. This incorporates confirmation that the sample was sealed and dispatched correctly, the assignment of a random LAN (Laboratory Accessioning Number), and the completion of any missing information from an electronic chain of custody system.
Screening entails a preliminary swift assessment for abuse drugs. Although Screening is an economical method to eliminate drug use for most samples, a positive screen must be validated to be permissible in legal settings. Any samples that test presumptively positive during Screening necessitate an additional confirmation.
When a sample tests positive during the Screening phase, additional hair is gathered from the initial sample and made ready for Extraction. Drugs are extracted from hair at much reduced concentrations than in other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
Positive screening results are confirmed through methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation as necessary. The comprehensive lab process from Accessioning through Confirmation is overseen under the CAP (College of American Pathologists) Hair standard and the ISO/IEC 17025 accreditation.
