Hair analysis is widely regarded as an effective method for identifying substance and alcohol consumption. Hair offers an extended history of substances by capturing identifiers within the strands as they grow. When taken from near the scalp, it can indicate substance use for up to roughly three months. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A 1.5-inch portion of roughly 200 hair strands similar to the circumference of a #2 pencil yields 100mg of hair, which is perfect for both screening and confirmatory testing. For EtG, enhancements, or tests beyond 10 panels, a quantity of 150mg is advised. It’s best to measure the sample using a jeweler’s scale. If scalp hair isn’t accessible, a similar quantity of body hair can be collected. ‘Head hair’ refers specifically to scalp hair. ‘Body hair’ covers all other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning relates to the preliminary input of a specimen into a lab's framework. It ensures that the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and fills any data gaps not covered by an electronic chain of custody.
Screening is a preliminary analysis for substance misuse. Though it’s a budget-friendly way to dismiss drug consumption in most cases, a conclusive positive screen must be confirmed for court viability. Samples that test positive in Screening need further confirmation.
Should a sample test presumptively positive in Screening, more hair is extracted from the initial sample for Extraction. Here, substances are obtained from hair at significantly lower concentrations than in other methods (like urine or oral fluid), explaining why hair drug testing is particularly challenging.
Confirmation of any positive screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples are cleansed as necessary before confirmation. The entire lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although referred to as "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp.
