Hair testing is increasingly recognized as an effective method for detecting drug and alcohol usage. It offers a historical overview of substance intake by embedding biomarkers within the hair shaft. Collected near the scalp, hair can provide a detection span of up to three months for alcohol and other substances. The collection process is straightforward, it's less prone to tampering, and it is easy to transport.
A 1.5-inch sample consisting of approximately 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg, which is the preferred amount for both screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, a 150mg sample is suggested. We advise verifying the sample weight using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent volume of body hair can be used. “Head hair†refers solely to scalp hair, whereas “body hair†includes all other types (like facial or axillary hair).
Process Overview
In the lab processing for a drug test result, there are four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed within the lab’s system. This step confirms the sample's proper sealing and shipment, assigns it a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry not covered by an electronic chain of custody system.
Screening checks for drug use quickly. It’s an economical method for ruling out drug usage in most cases, but only a confirmed positive screen is valid for legal purposes. Samples that test as presumptively positive during Screening necessitate further confirmation.
When a sample tests presumptively positive during Screening, additional hair is taken from the original sample for the Extraction process. In Extraction, drug traces are isolated from the hair at lower concentrations than what is found in other methods (such as urine or saliva), making hair testing one of the most challenging methodologies.
Confirmation of any presumptively positive results is done through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptively positive samples undergo a wash as necessary. The entire process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair program and aligns with ISO / IEC 17025 standards.
