Hair testing has emerged as a formidable means for identifying drug and alcohol consumption. Hair strands capture a lengthy record of alcohol and drug intake by locking biomarkers within the fibers of the hair as it grows. When harvested near the scalp, hair offers nearly a 3-month period for spotting alcohol and drug presence. Hair collection is straightforward, relatively hard to tamper with, and convenient for shipping.
A 1.5-inch section of around 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will yield 100mg, which is optimal for both screening and confirming tests. For EtG tests, additional testing, or tests exceeding 10 panels, it is advised to collect 150mg of hair. Using a jeweler’s scale for weighing the specimen is recommended. If head hair isn't available, a comparable quantity of body hair may be obtained. When we mention head hair, we exclusively refer to scalp hair, whereas body hair refers to other types like facial and axillary hair.
Process Overview
The laboratory analysis of a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is entered into a laboratory’s system. It involves confirming the proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not completed by an electronic chain of custody.
Screening is a preliminary quick test for illicit drug use. While Screening serves as an economical method to exclude drug presence in most samples, a positive screen needs to be validated for legal acceptability. Presumptive positives from Screening necessitate secondary confirmation.
Should a sample test presumptively positive during Screening, more hair is extracted from the initial sample for the Extraction phase. During this step, drugs are isolated from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the toughest method to perform.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptive positive undergo washing as necessary before confirmation. The complete laboratory process from Accessioning through Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
