Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a chronological record of alcohol and drug use by embedding biomarkers within the hair strands as they grow. Sampling hair close to the scalp can offer a detection period of up to roughly three months for alcohol and drugs. It is easy to collect hair samples, they are relatively tamper-resistant, and straightforward to transport.
A 1.5-inch hair snippet comprising approximately 200 strands (equivalent to the width of a #2 pencil) from near the scalp yields 100mg of hair, which is the ideal quantity for both screening and confirmation tests. For EtG, additional tests, and panels exceeding 10, it is advisable to collect 150mg of the sample. Utilizing a jeweler’s scale for accurate measurement of the hair sample is recommended. In instances where scalp hair is not available, a similar quantity of body hair may be collected. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other types, including facial, axillary, etc.
Process Overview
The laboratory procedure for processing drug test results involves four major steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into a laboratory’s system. This step ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entries not covered by an electronic chain of custody system.
Screening is an initial rapid assessment for drugs of abuse. While Screening is a cost-effective method to eliminate drug usage in most samples, any positive Screening result must be confirmed for it to be valid in court. Samples that show presumptive positive results in Screening do require additional confirmation.
In cases where a sample tests presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug testing one of the more challenging methodologies to conduct.
The Confirmation of any positive screenings is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. Throughout the entire laboratory process, from Accessioning to Confirmation, standards are upheld according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
