Hair analysis has emerged as an effective approach for identifying the consumption of substances. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. Collecting hair close to the scalp can reveal a detection window of up to 90 days for various substances. Hair collection is straightforward, relatively immune to tampering, and easy to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to the diameter of a #2 pencil) situated near the scalp equates to 100mg of hair, which is the preferred amount for assessment and validation. For EtG or tests exceeding 10 panels, it is advised to use 150mg of the sample. We advocate for measuring the specimen with a jeweler’s scale. If scalp hair is not available, a comparable volume of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair denotes all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory process for evaluating a drug test result comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into the laboratory’s system. This step involves ensuring the sample is sealed and transported correctly, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included by an electronic chain of custody.
Screening is a preliminary assessment for detecting drug abuse. Although Screening offers an economical method to eliminate drug use in most samples, any positive result must be verified to be valid in legal settings. Samples that test positive in Screening necessitate follow-up confirmation.
In cases where a sample tests positive during the Screening, additional hair is extracted from the original sample and prepared for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations than other methods (like urine or oral fluid), which is why hair drug analysis is considered challenging.
Verification of any positive result from Screening is done through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results are cleansed prior to verification as needed. From Accessioning to Confirmation, the entire laboratory process is scrutinized under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
