Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair acts as a chronic archive of substance usage by embedding biomarkers within the fibers of the developing hair strands. When harvested near the root, hair can reveal drug and alcohol use over a span of up to 90 days. Collecting hair is straightforward, resistant to tampering, and convenient for postage.
A 1.5-inch sample consisting of roughly 200 hair strands (similar in size to a #2 pencil) from the scalp offers 100mg of hair, which is the perfect amount for both analysis and verification. For tests such as EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advisable. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, the same amount of body hair can be used as an alternative. By head hair, we mean scalp hair specifically. Body hair refers to all other types of hair (facial, axillary, etc.).
Process Overview
The key stages in the laboratory process for drug test evaluation are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary incorporation of a sample into a lab’s database. This process entails verifying the integrity and correct shipment of the sample, generating an arbitrary LAN (Laboratory Accessioning Number), and completing any further data input absent from an electronic chain of custody system.
Screening is an initial rapid evaluation to detect substances of misuse. Although Screening is an economical approach to eliminate drug usage for most samples, positive screens must be validated to be credible in legal settings. Samples that show likely positivity during Screening necessitate follow-up confirmation.
For presumptive positive samples in the Screening phase, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are derived from hair at concentrations far lower than those in methods like urine or saliva testing, making hair drug screening notably challenging.
The confirmation of positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with presumptive positivity undergo a pre-confirmation wash as required. The complete laboratory procedure from Accessioning through Confirmation is assessed under CAP (College of American Pathologists) Hair designation and endorsed by ISO / IEC 17025 standards.
