Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. The hair acts as a long-term reservoir for alcohol and drug markers, capturing these indicators in the growing hair shaft fibers. When taken near the scalp, it can offer an approximately 3-month detection period for alcohol and other substances. Hair is easy to obtain, challenging to tamper with, and convenient to send.
A 1.5-inch hair segment of roughly 200 strands (comparable to a #2 pencil's thickness) closest to the scalp equates to 100mg of hair, the perfect amount for testing and verification. For EtG, add-ons, or assays exceeding 10 panels, 150mg of the sample is advised. It's best to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, a similar quantity of body hair can be utilized. Mentioning head hair refers strictly to scalp hair. Body hair encompasses other varieties (like facial or axillary hair, etc.).
Process Overview
The laboratory procedure of processing a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is introduced to a laboratory’s framework. This step validates that the sample was sealed and transferred correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any further data entry absent from an electronic custody system.
Screening is a preliminary rapid evaluation for drug substances. Screening serves as an affordable method to exclude drug usage in most specimens, although any positive screen requires verification to be valid in court. Samples that yield a presumptive positive in Screening necessitate a secondary confirmation.
If a sample tests presumptive positive in Screening, more hair is extracted from the original sample and set for Extraction. At this point, substances are pulled from hair at significantly lower levels than other techniques (like urine or oral fluid), showing why hair testing is the hardest methodology to execute.
Verification of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptively positive specimens undergo washing before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is assessed under the supervision of both CAP (College of American Pathologists) Hair certification and the accreditation to ISO / IEC 17025 standards.
