Hair assessments have emerged as an effective resource for identifying the consumption of drugs and alcohol. Hair strands capture a long-term usage history of these substances by embedding biomarkers within the fibers of the hair as it grows. When hair is sampled near the scalp, it can offer close to a three-month window of detection for alcohol and drug use. This method is straightforward to administer, challenging to tamper with, and easy to transport.
A hair sample of 1.5 inches, consisting of nearly 200 strands (approximately the thickness of a #2 pencil) near the scalp, provides 100mg of hair, which is considered an ideal amount for both screening and verification testing. For EtG, additional assessments, or testing beyond 10 drug panels, a 150mg sample is suggested. It is advised to measure the sample on a jeweler’s scale. If scalp hair cannot be sourced, a comparable portion of body hair can be used. When discussing head hair, it specifically pertains to scalp hair. Body hair encompasses other varieties (beard, underarm, etc.).
Process Overview
The drug testing laboratory procedure involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples are initially processed into the laboratory’s database. This stage confirms that samples were correctly sealed and shipped, allocates a unique LAN (Laboratory Accessioning Number), and fills in any extra information not included in an electronic chain of custody.
Screening serves as an initial rapid assessment for drug presence. While Screening is an economical approach to exclude drug use in the majority of samples, any positive preliminary findings must be verified to stand up in legal situations. Samples that test presumptively positive in Screening move on to a confirmation phase.
If Screening indicates a presumptive positive, further hair is extracted from the initial sample for the Extraction phase. Here, substances are separated from hair at concentrations significantly lower than those seen in other testing methods (e.g., urine or saliva), contributing to the complexity of hair drug testing.
Confirmation of a positive screen involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo cleansing before confirmation when needed. The complete procedure, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair requirements and ISO / IEC 17025 accreditation.
