Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis is widely recognized as an effective means for detecting drug and alcohol consumption. Hair acts as a repository for long-term substance history by embedding biomarkers within its strands as they grow. When collected near the scalp, hair offers a detection period of up to around three months for both alcohol and other drugs. It is easy to gather, challenging to tamper with, and straightforward to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal amount for initial screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale is recommended to weigh the specimen. If scalp hair isn't available, an equivalent body hair amount can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses initial sample processing within a lab's system. This phase confirms proper sealing and shipping of the sample, assigns a LAN (Laboratory Accessioning Number), and addresses any extra data entry absent from electronic chain of custody procedures.
Screening serves as a preliminary check for substances. While it's a cost-efficient method to discount drug use in the majority of samples, confirmed positive results are necessary for legal validity. Presumptively positive samples during Screening necessitate further confirmation.
For samples deemed presumptively positive during Screening, more hair is sourced from the original sample and readied for Extraction. At this stage, drugs are isolated from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening a particularly challenging methodology.
Confirmation for any preliminary positive results is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, presumptive positive samples are cleansed when required. The entire pathway from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often misidentified as "hair follicle tests", the procedure evaluates the hair strand rather than the follicle beneath the scalp.
