The utilization of hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains a historical record of substance usage by embedding biomarkers within the strands. When sampled near the scalp, hair can indicate drug and alcohol presence over an estimated three-month period. The collection process is straightforward, making tampering challenging, and ensuring easy transportation.
A sample measuring 1.5 inches, containing roughly 200 strands (comparable to a #2 pencil's thickness), collected closest to the scalp, yields 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, or screenings exceeding 10 panels, a 150mg quantity is suggested. We advise employing a jeweler’s scale for specimen weighing. In the absence of scalp hair, a comparable volume of body hair can be used. Specifically, "head hair" pertains exclusively to scalp hair, while "body hair" encompasses all other types, such as facial and axillary.
Process Overview
The laboratory analysis of a drug test result is structured into four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial step where a sample is incorporated into a laboratory’s workflow. This phase ensures the sample's integrity and proper shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data input absent from an electronic chain of custody.
Screening serves as an introductory, efficient assessment for substance abuse detection. While Screening economically eliminates drug presence in most cases, a positive result necessitates confirmation for legal validity. Presumptively positive samples detected during Screening must undergo additional verification.
In cases where a sample tests presumptively positive during Screening, extra hair is derived from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
To validate positive Screening results, Confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples identified as presumptively positive are cleansed pre-confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation per ISO / IEC 17025 standards.
