Hair analysis has emerged as a potent means for identifying alcohol and drug consumption. Hair offers a prolonged timeline of substance use by capturing biomarkers within its fibers during growth. By sampling near the scalp, hair can reveal a detection range of up to about 90 days for alcohol and drugs. Hair is easy to collect, hard to tamper with, and simple to transport.
Collecting a 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's size) from near the scalp yields 100mg of hair, which is the perfect amount for assessment and verification. For EtG, additional analyses, or panels beyond 10, a 150mg sample is advised. Using a jeweler's scale for measurement is suggested. If there is no scalp hair available, a similar quantity of body hair can be gathered. When mentioning head hair, it specifically pertains to scalp hair only, while body hair includes any other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result involves four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is processed into a lab's system. This step ensures the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry not provided by an electronic chain of custody system.
Screening is a preliminary and cost-effective process to check for drug misuse. Though it rules out drug usage in most samples, positive results need confirmation for legal validity. Specimens that test positive initially require a secondary verification.
Should a sample test positive in the Screening stage, additional hair from the initial sample is prepared for Extraction. During Extraction, drugs are separated from hair at lower concentrations than other methods (e.g., urine or oral fluid), making hair analysis the most challenging to execute.
Confirmation of positive screening results is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of all presumptive positive samples takes place before confirmation. The full laboratory progression from Accessioning to Confirmation is examined under CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the procedure examines the hair strand, not the follicle under the scalp.
