Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and drugs by capturing biomarkers in the fibers of the growing hair. When samples are taken near the scalp, hair testing can provide around a 3-month detection period for alcohol and drugs. It is easy to collect, quite resistant to tampering, and straightforward to transport.
A sample measuring 1.5 inches with roughly 200 strands (around the diameter of a #2 pencil) nearest the scalp will produce 100mg of hair, which is the optimal sample for screening and confirmatory purposes. For EtG, additional tests, or examinations beyond 10 panels, a specimen of 150mg is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair can be used. When we mention head hair, we refer solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key steps in laboratory analysis of a drug test result comprise: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory system. This task includes ensuring the sample was properly sealed and shipped, providing a random LAN (Laboratory Accessioning Number), and completing any extra data entry that an electronic chain of custody system might not supply.
Screening is a preliminary assessment for detecting drugs of abuse. While Screening is economically efficient for eliminating samples without drug usage, positive results require confirmation for legal acceptability. Any samples that test presumptively positive in Screening need a follow-up confirmation.
If a specimen tests presumptively positive during Screening, further hair is extracted from the original sample for the Extraction process. This phase extracts drugs from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug testing presents the most challenges in methodologies.
Confirmation for any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washing before confirmation, if necessary. The full laboratory procedure from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: While often called "hair follicle tests," the actual analysis examines the hair strand and not the follicle below the scalp.
