Hair analysis has grown in recognition as an efficient method for identifying drug and alcohol consumption. Hair retains a comprehensive record of substance use by embedding biomarkers within the strands as they grow. When sourced near the scalp, hair can offer around a three-month observation period for alcohol and drug presence. The collection process for hair is straightforward, with minimal risk of tampering, and it's convenient for transportation.
A hair sample measuring 1.5 inches comprising roughly 200 strands (similar to a #2 pencil) adjacent to the scalp will yield 100mg of hair, which is the optimal amount for testing and verification. For EtG, accessories, and/or examinations exceeding 10 panels, a larger specimen weighing 150mg is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is inadequate, a matching quantity of body hair can be collected. Referring to head hair strictly means scalp hair. Body hair pertains to all other forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug testing outcome comprises four main phases: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, a sample undergoes initial processing into a laboratory setup. This phase includes checking the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data input not covered by an electronic custody chain system.
The Screening phase entails a preliminary swift check for abused substances. Although Screening is a budget-friendly method to dismiss drug usage in many cases, a positive result must be substantiated for court acceptance. Any samples that are presumptively positive in Screening require further verification.
During the Screening stage, if a sample is indicated as presumptively positive, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from hair at much lower levels than with other techniques (e.g., urine or oral fluid), making hair drug screening a challenging procedure.
The Confirmation of any positive result from the screening phase is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptively positive undergo washing before Confirmation as required. The comprehensive laboratory handling from Accessioning to Confirmation is scrutinized both under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 certification standards.
