Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair can provide a prolonged record of alcohol and drug intake by encapsulating biomarkers within the growing strands. When gathered near the scalp, hair can indicate substance usage for up to roughly three months. The collection process is straightforward, with a reduced risk of tampering, and samples are easily transportable.
A 1.5-inch section of around 200 hair strands (comparable to a #2 pencil's thickness) nearest the scalp yields 100mg of hair, which is ideal for screening and confirmation. For EtG, additional tests, and those over 10 panels, it is advisable to use 150mg of the sample. For accuracy, the specimen should be weighed using a jeweler’s scale. Should scalp hair not be an option, a similar quantity of body hair may be gathered. When we mention head hair, we mean only scalp hair. Body hair encompasses all other hair types (like facial and axillary).
Process Overview
The laboratory processing of a drug test outcome primarily involves Accessioning, Screening, Extraction, and Confirmation stages.
Accessioning is the initial phase, where a sample is integrated into a laboratory’s system. This step involves verifying appropriate sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening entails a preliminary inspection for substances of misuse. Though Screening offers a cost-effective way to negate substance usage in most samples, a positive screen must be validated for court admissibility. Any samples preliminarily positive in Screening need further confirmation.
Should a sample be preliminarily positive at the Screening stage, an additional hair portion is taken from the initial sample and readied for Extraction. Here, substances are extracted from hair at significantly lower concentrations than other methods (like urine or oral fluid), making hair drug screening among the most challenging methods to execute.
Confirmation of any positive screen is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive are cleansed prior to confirmation as necessary. The complete laboratory phase from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
