Hair analysis has become recognized as an effective method to identify drug and alcohol consumption. This method offers an extended record of substance use by embedding biomarkers within the strands of the growing hair. When cut close to the scalp, hair can reveal alcohol and drug use for a period of up to about three months. It is straightforward to gather, relatively resistant to tampering, and convenient for transportation.
Collecting a 1.5-inch segment from about 200 strands of hair nearest the scalp yields around 100mg, which is ideal for analysis and verification. For EtG, additional tests, and/or screenings beyond 10 panels, a sample size of 150mg is suggested. It is advisable to measure the sample with a jeweler’s scale. In cases where scalp hair cannot be obtained, an equivalent amount of body hair can be used. References to head hair denote only scalp hair, whereas body hair pertains to all other hair types (e.g., facial, axillary).
Process Overview
There are four principal stages in the analytical process of drug test results, which are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial reception of a sample into the lab’s system. This step includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data entry not completed by an electronic chain of custody methodology.
Screening conducts a preliminary evaluation for substances of abuse. While it serves as an economical measure to screen out drug usage in most cases, a positive result here must be verified to be legally valid. Samples indicating presumptive positives at Screening must undergo secondary confirmation.
Should Screening indicate a presumptive positive, additional hair is sourced from the original sample for the Extraction phase. Here, substances are separated from the hair at concentrations much lower than with other techniques (such as urine or oral fluid), making hair drug testing the most complex method to perform.
To confirm any positive results from Screening, methods like GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples with presumptive positives undergo necessary cleaning before confirmation. The complete laboratory progression from Accessioning to Confirmation is overseen according to both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
