Hair sampling is recognized as an effective method for identifying drug and alcohol consumption. It offers a comprehensive timeline of substance intake by capturing biomarkers within the strands of the hair as it grows. When collected near the scalp, hair can offer a detection period extending up to roughly 3 months for drugs and alcohol. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.
A 1.5-inch section of about 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample size for both initial screening and further confirmation. For EtG, additional analyses, and/or tests surpassing 10 panels, 150mg of hair is suggested. We advise validating the specimen weight with a jeweler’s scale. If scalp hair is absent, a comparable quantity of body hair can be utilized. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test results in a laboratory setting encompass four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's preliminary processing within the laboratory’s system. This step includes verifying the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry omitted by an electronic chain of custody system.
Screening provides an initial swift assessment for illicit drug presence. Although Screening offers a cost-efficient approach for excluding drug use in most samples, a positive result demands confirmation for legal admissibility. Samples that are initially positive in Screening necessitate a secondary validation.
Should a sample be initially positive during the Screening phase, additional hair from the same sample is gathered for Extraction. In this stage, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), presenting hair drug screening as the most challenging methodology.
Any positive screening outcomes undergo confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to confirmation as required. The comprehensive laboratory procedure from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standards and the accreditation complying with ISO / IEC 17025 standards.
