Hair analysis has gained recognition as an effective technique for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of alcohol and substance intake by embedding biomarkers within the strand's fibers. When gathered near the scalp, hair can offer a visibility period of nearly three months for alcohol and various drugs. It is straightforward to collect, challenging to tamper with, and simple to transport.
A 1.5-inch section containing roughly 200 hair strands (resembling the diameter of a #2 pencil) closest to the scalp generates 100mg of hair, the optimal quantity for evaluation and verification. For EtG, add-ons, and/or examinations exceeding 10 panels, it is advised to obtain 150mg of the sample. Utilizing a jeweler’s scale is recommended for measuring the specimen. If scalp hair is inaccessible, a proportional amount of body hair can be gathered. The term "head hair" specifies only scalp hair, while "body hair" encompasses other hair types (e.g. facial, axillary).
Process Overview
The primary steps in laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves processing a sample's entry into the laboratory’s procedure. This step ensures the sample's proper sealing and transit, generates a random LAN (Laboratory Accessioning Number), and concludes any extra data entry absent in an electronic chain of custody system.
Screening entails an expedited evaluation for substances of abuse. Although Screening offers a cost-efficient means to negate drug use in most instances, positive Screening results require confirmation to be courtroom admissible. Samples yielding a presumptive positive in Screening necessitate secondary validation.
Should a sample exhibit a presumptive positive during Screening, additional hair is derived from the original sample for Extraction. At this point, drugs are extracted from hair at significantly lower concentrations compared to alternate techniques (such as urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirmation of any positive Screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before Confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Frequently termed as "hair follicle tests," the examination actually assesses the hair strand, not the follicle beneath the scalp.
