The utilization of hair analysis has evolved into a significant method for uncovering drug and alcohol consumption. By embedding biomarkers within the fibers of the expanding hair strand, hair offers an extensive historical record of substance use. When sampled near the scalp, hair can reveal a detection period of up to about three months for drugs and alcohol. Collecting hair is a straightforward process, somewhat resistant to tampering, and uncomplicated to transport.
Collecting a sample of 1.5 inches of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is perfect for initial and confirmatory testing. For assessments like EtG, additional panels, or tests exceeding 10 panels, a specimen mass of 150mg is advised. Measuring the specimen on a jeweler’s scale is suggested. In the absence of scalp hair, a comparable volume of body hair may be obtained. In the context of head hair, it specifically means scalp hair. Body hair denotes all other hair variations (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test outcome encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes its initial intake into a lab’s process. This phase entails checking the sample's sealing and shipping correctness, generating a random LAN (Laboratory Accessioning Number), and completing additional data input absent in an electronic custody chain.
Screening serves as the primary rapid evaluation for drug traces. Although Screening is an economical method to dismiss drug presence in most samples, a confirmed positive result is required for legal acceptability. Samples with preliminary positive results in Screening require a mandatory follow-up Confirmation.
Should a sample test presumptively positive during Screening, supplementary hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at a lower concentration than other methods (e.g., urine or oral fluid), thus making hair drug testing the most challenging to execute.
Verification of any gridline positive screen outcomes is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with potential positive test results undergo cleaning before confirmation if needed. The complete lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standard accreditation.
