Hair tests have gained recognition as an effective mechanism for identifying substance use. Hair captures a prolonged history of drugs and alcohol by embedding biomarkers within the growing strand's fibers. When taken near the scalp, it can offer up to roughly a 90-day detection window. It is straightforward to gather, challenging to tamper with, and easy to mail.
A 1.5-inch segment, containing approximately 200 hairs (akin to the size of a #2 pencil) nearest to the scalp, yields 100mg, the optimal sample for analysis. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. We suggest using a jeweler's scale for specimen measurement. If scalp hair isn't present, corresponding body hair may be acquired. "Head hair" specifically pertains to scalp hair, while "body hair" includes other varieties (like facial or axillary hair).
Process Overview
The main stages in lab processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This involves ensuring the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data entry omitted by an automated chain of custody system.
Screening involves a preliminary quick assessment for substance abuse. While Screening serves as a cost-efficient approach to exclude drug use for most samples, a positive result requires verification for court admissibility. Any samples identified as potentially positive in Screening mandate a further confirmation step.
If a sample registers as potentially positive during Screening, more hair is extracted from the original sample for Extraction. Here, drugs are derived from hair at much lower concentrations than other techniques (e.g., urine or oral fluids), making it the most challenging drug screening method.
Any positive screening outcome undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation if necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is assessed under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests", the assessment targets the hair strand, not the follicle beneath the scalp.
