Hair testing is now regarded as an effective means for detecting drug and alcohol usage. Offering a long-term view of substance use, hair strands capture biomarkers within their growing fibers. When taken near the scalp, hair can provide an approximate 3-month detection period for substances. Hair sampling is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch section containing about 200 hair strands (approximately the width of a #2 pencil) from the scalp will yield 100mg, the optimal quantity for initial and confirmatory testing. For EtG, extended panels, or tests exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler's scale to ensure accurate measurement. If scalp hair is insufficient, a similar amount of body hair can be used. "Head hair" specifically refers to scalp hair. "Body hair" encompasses other types (facial, axillary, etc.).
Process Overview
Lab processing of a drug test result follows four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with integrating a sample into a lab system. It ensures the sample was sealed and shipped correctly, assigns a Laboratory Accessioning Number (LAN) randomly, and fills any missing data not included in an electronic chain of custody.
Screening provides a preliminary evaluation for substance abuse. Although Screening offers a cost-effective method to dismiss drug usage for most samples, a positive result requires confirmation for court validity. Samples that show a presumptive positive in Screening proceed to a secondary confirmation.
Should a sample test as presumptively positive during Screening, additional hair is extracted from the main specimen and prepared for Extraction. Here, drugs are isolated from hair at concentrations lower than those in other testing methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any positive results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives are cleaned before Confirmation, as necessary. The laboratory process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.
