Hair sampling is recognized as an effective approach for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the fibers of the growing hair shaft. By collecting hair near the scalp, a detection range of up to about 3 months for alcohol and drugs can be achieved. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (nearly the width of a #2 pencil) near the scalp will yield 100mg, which is ideal for screening and confirmation procedures. For EtG, add-ons, or tests beyond 10 panels, a 150mg sample is preferred. We advise using a jeweler’s scale to weigh the sample. If scalp hair cannot be obtained, a comparable amount of body hair is permissible. When mentioning head hair, we mean scalp hair specifically. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory handling of drug test results encompasses four core stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the preliminary integration of a sample into a lab’s framework. Verifying the proper sealing and shipment of the sample, allocating a unique LAN (Laboratory Accessioning Number), and addressing any extra data entry not provided by an electronic chain of custody system are part of this stage.
Screening provides a primary check for drugs of abuse. While Screening is a cost-efficient method to eliminate drug use on most samples, a positive screening necessitates confirmation for court admissibility. Samples testing presumptively positive during Screening require additional confirmation.
If presumptive positivity is observed during the Screening phase, extra hair is extracted from the original sample and readied for Extraction. Here, drugs are removed from hair at significantly lower levels than other methods (ex. urine or oral fluid), which is why hair drug screening is one of the most challenging techniques to perform.
GC/MS, GC/MS/MS or LC/MS/MS is used to confirm any positive screening results. Presumptively positive samples undergo washing before confirmation, if needed. Every step from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Limitations:
Note: Though termed "hair follicle tests", the test actually evaluates the hair strand, not the follicle underneath the scalp.
