Hair testing is now recognized as an effective method for detecting alcohol and drug usage. By embedding biomarkers within the fibers, hair offers an extended overview of substance use. When hair is clipped close to the scalp, it provides a detection timeline of nearly three months for substances. Collecting hair is straightforward, relatively tamper-resistant, and easy to transport.
A sample consisting of 1.5 inches of about 200 hair strands (resembling the size of a #2 pencil) taken nearest to the scalp yields around 100mg of hair, which is optimal for both screening and verification. For EtG augmentation and/or panels exceeding 10, a 150mg sample is advised. It's suggested to use a jeweler’s scale for specimen weighing. If scalp hair is not collectable, a comparable amount of body hair can be used. "Head hair" strictly denotes scalp hair, while "body hair" covers all other types (such as facial or underarm hair).
Process Overview
Four primary stages constitute the lab processing to acquire a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the introduction of a sample into the lab’s framework. This involves checking the sample's seal and correct shipping, allocating a LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic custody system.
Screening offers a preliminary assessment for substance misuse. Although Screening is an affordable approach to dismiss drug usage in most samples, court acceptance requires a confirmed positive result. Presumptively positive Screening findings mandate further confirmation.
Upon obtaining a presumptively positive Screening result, additional hair is gathered from the original sample for Extraction. Here, drugs are extracted from hair at markedly lower levels compared to other techniques (like urine or oral samples), making hair drug testing the most challenging to execute.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples marked presumptive positive are cleaned before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
