Hair analysis is recognized as an effective method for detecting substance use. It offers a prolonged record of alcohol and drug intake by embedding biomarkers within the strands as they grow. Hair samples collected near the scalp can provide a detection timeframe of up to three months for substances. This form of testing is easy to gather, hard to tamper with, and straightforward to dispatch.
An ideal specimen for testing and validation requires a 1.5-inch section of around 200 hair strands (roughly matching the size of a #2 pencil) closest to the scalp, yielding 100mg of hair. For testing including EtG, add-ons, or panels exceeding 10, a 150mg sample is advisable. It's best to measure the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair can be used. "Head hair" specifies scalp hair only, whereas "body hair" encompasses other types (such as facial or axillary hair).
Process Overview
The four core phases of laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the initial steps involve integrating a sample into a laboratory system, ensuring it was sealed and transported properly, assigning it a unique LAN (Laboratory Accessioning Number), and completing any absent data entry from an electronic chain of custody protocol.
The Screening phase offers a preliminary assessment for substances. Though efficient and economical for ruling out drugs in most specimens, any positive result in Screening requires confirmation for legal validity. Samples indicating potential positivity from Screening necessitate additional verification.
Presumptive positives from Screening undergo further examination during the Extraction stage, where more hair is taken from the specimen. Here, drugs are extracted from hair at a concentration much lower than other methods like urine or saliva, making hair testing particularly challenging.
Confirming positive screenings involves techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Every sample suspected positive is thoroughly washed before confirmation if needed. The entire workflow, from Accessioning to Confirmation, is audited under CAP’s Hair classification and meets ISO/IEC 17025 accreditation standards.
