Hair Follicle Drug Testing - Monolith, CA

What it is, How it works

Hair analysis is becoming recognized as a significant method for identifying drug and alcohol consumption. Hair strands record a comprehensive timeline of substance use by embedding biomarkers within the hair's growing fibers. When collected near the scalp, hair can offer around a three-month detection range for both alcohol and drugs. Hair is straightforward to gather, somewhat hard to tamper with, and simple to transport.

A hair sample measuring 1.5 inches from about 200 strands (approximate size of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, additional tests, or tests beyond ten panels, a specimen amount of 150mg is suggested. It's advised to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair is permissible. References to head hair imply only scalp hair. Body hair encompasses all other hair forms (such as facial or axillary types).

Process Overview

The four essential phases in laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the sample's processing within a laboratory's system. This phase includes confirming that the sample was properly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and completing any further data input not supplied by an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. While Screening is an economical method to exclude drug use in most samples, a screen yielding positive requires confirmation for court admissibility. Any samples that show presumptive positivity in Screening need a secondary verification.

Should a sample show presumptive positivity during Screening, additional hair is drawn from the primary specimen for the Extraction phase. In this phase, drugs are extracted from hair at considerably lower concentrations compared to other methodologies (such as urine or oral fluid), rendering hair drug screening the most challenging method to execute.

Positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleaned before confirmation as necessary. The full laboratory process from Accessioning to Confirmation undergoes review under both the College of American Pathologists (CAP) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection span: Hair drug tests identify drug use for up to 90 days, unlike urine tests which have a briefer detection duration.
• Difficult to falsify: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Offers historical insight: It can demonstrate a history of drug use over time, not just recent activity.

Limitations:

• Inability to detect recent usage: Drugs take roughly 5-7 days to become detectable in hair.
• Cost implications: Hair drug tests tend to be costlier than alternate drug testing approaches.
• Result disparities: Factors like hair color and personal differences in hair growth can impact drug metabolite levels in hair.

Note: Although frequently termed as "hair follicle tests", the analysis evaluates the hair strand and not the follicle beneath the scalp.
