Regarded as a robust measure in detecting drug and alcohol consumption, hair testing captures a prolonged history of substance use by embedding biomarkers within the fibers of hair as it grows. When gathered near the scalp, hair samples can reveal usage over around a 3-month span for alcohol and other narcotics. Hair collection is straightforward, challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches and containing roughly 200 hair strands (similar in size to a #2 pencil) from near the scalp yields 100mg of hair, which is the optimal sample size for analysis and verification. For tests involving EtG, additional substances, and panels exceeding 10, 150mg of hair is advisable. We suggest using a jeweler's scale to weigh the specimen. If scalp hair cannot be sourced, a comparable amount of body hair may be collected. By head hair, we specifically mean scalp hair. Body hair encompasses any other hair types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial phase where the sample is entered into the lab's database, ensuring the specimen was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional information not covered by an electronic chain of custody system.
Screening is a preliminary drug detection check. While a cost-efficient method to exclude drug consumption in most cases, a positive screening result must be verified for legal admissibility. Any samples indicating a presumptive positive from Screening necessitate further confirmation.
If Screening suggests a presumptive positive, additional hair is extracted from the initia source and prepared for Extraction. At this stage, drugs are isolated from hair at significantly lower concentrations compared to other methods (for example, urine or oral fluid), illustrating why hair drug analyses present considerable complexity.
Confirmation for any positive screening finding is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if required. The complete laboratory process from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 standards.

Note: Despite being termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
