The analysis of hair has emerged as an influential medium for identifying the presence of drugs and alcohol. Hair captures an extended history of substance consumption by embedding biomarkers within the strands as they grow. When sampled near the scalp, hair can offer a detection period spanning up to three months for both alcohol and drugs. The collection process is straightforward, alteration is relatively challenging, and the shipment is uncomplicated.
A sample measuring 1.5 inches, consisting of about 200 hair strands (similar in diameter to a #2 pencil) closest to the scalp, yields 100mg of hair—ideal for both screening and confirmation. For tests including EtG, additional analyses, or those surpassing 10 panels, a specimen mass of 150mg is preferable. We advocate for the use of a jeweler’s scale for precise measurement. In the absence of scalp hair, an equivalent amount of hair from the body can be utilized. "Head hair" specifically pertains to scalp hair, while "body hair" encompasses other forms such as facial or underarm hair.
Process Overview
The laboratory processing of a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the initial incorporation of a sample into the laboratory's system. This covers the verification of intact and correctly dispatched samples, the allocation of a unique LAN (Laboratory Accessioning Number), and the completion of any unprovided data that doesn't come through an electronic chain of custody.
Screening conducts an initial quick scan to spot substances of abuse. Though cost-effective, a positive screen necessitates confirmation to stand as valid evidence in legal matters. Samples that register as presumptively positive via Screening require further confirmation.
If a sample tests positive during Screening, additional hair from the original collection is used for Extraction. In this stage, drugs are isolated from hair at notably lower concentrations compared to other methods like urine or oral fluid; hence, hair drug analysis presents considerable complexity.
Confirmation of positive screening outcomes is performed using either GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positives are cleansed before confirmation if required. The complete laboratory operation, from Accessioning through to Confirmation, is subject to scrutiny under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
