Hair analysis is recognized as an effective method for identifying the consumption of substances such as drugs and alcohol. Hair can capture a prolonged history of substance use by encasing biomarkers within the strands as they grow. When strands are collected from near the roots, hair testing can reveal substance usage over a period of up to three months. The collection process is straightforward, tampering is quite challenging, and the samples are easily transportable.
Collecting a 1.5-inch sample comprising around 200 hair strands (approximately the width of a #2 pencil) near the scalp results in about 100mg of hair, which is optimal for both screening and confirmation tests. For EtG, additional, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the hair on an accurate scale. If head hair isn't available, an equal quantity of body hair can be used. The term head hair specifically refers to scalp hair, while body hair includes all other types like facial or underarm hair.
Process Overview
The laboratory method for processing drug test outcomes involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial introduction of a sample into a laboratory system. This step verifies that the sample is sealed and dispatched correctly, assigns it a random LAN (Laboratory Accessioning Number), and completes any necessary additional data entry that isn't provided through an electronic chain of custody.
Screening serves as a preliminary evaluation for substances of abuse. Though it is a cost-efficient approach to eliminate drug use in most samples, any indication of drug presence must be confirmed for legal validity. Samples that test presumptive positive in Screening must undergo further confirmation.
Should a sample show positive preliminary results in Screening, additional hair is extracted from the initial sample, prepared for Extraction. This stage involves isolating drugs from hair, typically at a significantly lower concentration compared to other methods (such as urine or oral fluid), contributing to the complexity of hair drug testing.
Positive results in the Screening stage are validated through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Any samples deemed presumptive positive are cleansed prior to further confirmation, as necessary. The complete process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation.
