Hair testing is increasingly recognized as an efficient method for identifying drug and alcohol consumption. Hair retains biomarkers within its growing strands, offering a historical view of alcohol and drug usage. When sampled near the scalp, hair can reveal consumption details for up to a 90-day period. Collecting hair is straightforward, relatively tamper-proof, and convenient to transport.
A 1.5-inch portion comprising around 200 hair strands (comparable to the thickness of a #2 pencil) from the scalp produces 100mg of hair, the optimal amount for both screening and validation. For EtG, additional analyses, and tests exceeding 10 panels, a 150mg sample is advisable. It's suggested to measure the specimen using a jeweler’s scale. If scalp hair is sparse or unavailable, a comparable quantity of body hair may be gathered. Reference to head hair pertains strictly to scalp hair, while body hair encompasses other kinds (such as facial or axillary).
Process Overview
Four primary stages are involved in laboratory evaluation of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary entry of a specimen into the lab's framework. Tasks include ensuring the sample's proper sealing and delivery, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data requirement absent from an electronic chain of custody protocol.
Screening is a preliminary swift check for drug presence. It's a budget-friendly approach to ascertain substance usage in the majority of cases, although a positive screening needs additional verification for legal validity. Any specimens flagged as presumptively positive at this stage require subsequent confirmation.
When a specimen is flagged as positive in the Screening phase, additional hair segments are taken from the initial sample and prepped for Extraction. This phase involves extracting drugs at lower concentrations when compared to other methods like urine or oral fluid analysis. Hair drug screening represents the most challenging technique to execute.
Confirmation of any positive outcomes from screening is pursued using GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples undergo cleansing before confirmation if necessary. The full laboratory procedure, from Accessioning through Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation alongside certification to ISO / IEC 17025 criteria.
Advantages of hair drug testing:
Limitations:
Note: Although commonly dubbed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
