Hair testing has increasingly been recognized as an effective method for detecting drug and alcohol use. It offers a comprehensive history of substances by capturing biomarkers within the growing hair. A sample taken close to the scalp can offer a detection period of roughly 3 months for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient for shipping.
A sample of 1.5 inches, consisting of about 200 strands (resembling the size of a #2 pencil) nearest to the scalp, yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional panels, and tests exceeding 10 panels, 150mg is advisable. Using a jeweler’s scale for accuracy is suggested. Should scalp hair be unavailable, an equivalent amount of body hair is an option. The term "head hair" pertains strictly to scalp hair, while "body hair" encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The four cardinal phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of incorporating a sample into a lab’s system. This entails ensuring the sample’s proper sealing and shipment, the assignment of a random LAN (Laboratory Accessioning Number), and fulfilling any additional data entry absent from an electronic chain of custody system.
Screening is a preliminary inspection for drug abuse. Although Screening is an economical method to identify drug use in most samples, a positive finding must be confirmed for court acceptance. Presumptively positive samples in Screening necessitate a follow-up confirmation.
When a sample is deemed presumptively positive during Screening, more hair is extracted from the original specimen for further processing in Extraction. During this phase, drugs are isolated from hair in significantly lower concentrations than other methods (e.g., urine or oral fluid), illustrating why hair drug screening is notably challenging.
Any positive results from Screening are confirmed using GC/MS, GC/MS/MS or LC/MS/MS techniques. Presumptive positive specimens are washed pre-confirmation where necessary. The entire lab procedure, from Accessioning to Confirmation, is evaluated according to the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
