Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of drug and alcohol use by encasing biomarkers within the fibers of the growing strand. When taken close to the scalp, hair can indicate drug or alcohol intake over a nearly 3-month period. Collection is straightforward, tampering is somewhat challenging, and it is easy to ship.
A 1.5-inch portion of roughly 200 hair strands (about the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale for accuracy. If scalp hair is not available, a comparable amount of body hair can be collected. 'Head hair' refers exclusively to scalp hair. 'Body hair' includes all other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test follows four major stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial incorporation of a sample into a lab's system. This process entails confirming the proper sealing and shipment of the sample, issuing a random LAN (Laboratory Accessioning Number), and completing extra data entry absent from an electronic chain of custody system.
Screening consists of a preliminary assessment for drugs of abuse. Although Screening generally offers a cost-efficient means to exclude drug usage in the majority of samples, a positive result necessitates confirmation for court admissibility. Presumptively positive Screening samples require additional confirmation.
If a sample exhibits a presumptively positive result during Screening, further hair is sourced from the original specimen for Extraction. Here, the extraction of drugs from hair occurs at a much lower concentration than other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug testing.
Confirmation of any positive Screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo necessary washing prior to confirmation. The complete laboratory process, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly referred to as "hair follicle tests", the test itself evaluates the hair strand, not the follicle beneath the scalp.
