Hair screening is becoming recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of substance use, capturing biomarkers within the strands as they grow. If collected near the scalp, hair can offer up to an estimated 3-month window for detecting alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A segment of 1.5 inches comprising around 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimum quantity for both screening and verification. For EtG, additional tests, and tests beyond 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If head hair isn't available, an equivalent amount of body hair can be utilized. In context, head hair refers exclusively to scalp hair. Body hair pertains to all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab’s processes. This step verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.
Screening includes an initial rapid assessment for drug abuse. While it’s an economical strategy to exclude drug usage in most samples, a positive Screening outcome needs confirmation to be legally tenable. Samples considered presumptively positive during Screening indeed require secondary verification.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction process. In this phase, substances are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Verification of any positive Screening outcomes is completed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive undergo washing before confirmation as necessary. From Accessioning to Confirmation, the complete laboratory procedure is evaluated under both the CAP (College of American Pathologists) Hair criteria and compliance with ISO / IEC 17025 standards.
