Utilizing hair analysis is now recognized as an effective method to discover the presence of drugs and alcohol. Hair retains a comprehensive record of substances due to the entrapment of biomarkers within the strands as they grow. When hair is taken from near the scalp, it can reveal drug and alcohol usage over the past three months. Collecting hair is straightforward, tampering is relatively challenging, and shipping is uncomplicated.
Obtaining a section of 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil in width) from the scalp can yield around 100mg for ideal screening and confirmation purposes. For extended panels like EtG or those over 10 panels, 150mg is advisable. It is suggested to utilize a jeweler’s scale for measurement. If scalp hair cannot be acquired, body hair in equivalent amounts can be used. "Head hair" refers exclusively to scalp hair, while "body hair" pertains to other types such as facial or axillary hair.
Process Overview
There are four fundamental phases in lab processing of drug tests: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of the sample into the lab's listing. Steps include ensuring the sample's proper sealing and delivery, distributing a random LAN (Laboratory Accessioning Number), and finishing any extra data entry absent in the electronic chain of custody.
Screening is the preliminary inspection for controlled substances. Though cost-efficient, screening alone does not confirm drug presence legally, hence a secondary confirmation of positive outcomes is essential.
When a sample shows presumptive positive results at the Screening step, additional hair is extracted for Extraction. During Extraction, drugs are retrieved from hair at concentrations lower than those seen in other testing methods like urine or oral fluids, making hair drug testing particularly challenging.
GC/MS, GC/MS/MS, or LC/MS/MS techniques conduct the Confirmation of any positive screening results. All samples yielding presumptive positives undergo washing before confirmation as necessary. The comprehensive lab workflow from Accessioning through Confirmation is examined according to CAP (College of American Pathologists) Hair guidelines and accredited ISO / IEC 17025 standards.
