Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a longitudinal record of substance use by incorporating biomarkers within the strands as they grow. When hair is obtained near the scalp, it offers around a 3-month period for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches encompassing about 200 hairs (comparable in size to a #2 pencil) nearest the scalp will yield 100mg of hair, which is ideal for analysis and validation. For EtG, additional tests, or tests exceeding 10 panels, a sample of 150mg is advised. We suggest measuring the sample on a jeweler's scale. If scalp hair is not available, an equivalent quantity of body hair is acceptable. By head hair, we mean only scalp hair, whereas body hair refers to all other types (facial, axillary, etc.).
Process Overview
The drug test analysis in the lab comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with the sample's initial integration into a lab’s framework. This entails checking that the sample is appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not available through an electronic chain of custody system.
Screening is a preliminary evaluation to detect drug misuse. Although Screening is a cost-efficient approach for excluding drug usage in the majority of cases, a confirmatory test is necessary for a positive result to be legally valid. Samples with a presumptive positive in Screening must undergo subsequent verification.
Should a sample test presumptively positive during Screening, additional hair is processed from the initial sample for Extraction. In this stage, substances are isolated from hair at lower concentrations than other methods (such as urine or oral fluid), making hair drug screening one of the most complex methodologies.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are pre-washed before confirmation as needed. The complete lab process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
