Hair Follicle Drug Testing - Palo Verde, CA

What it is, How it works

Hair analysis is regarded as an effective means for identifying drug and alcohol consumption. Hair captures long-term evidence of substance use by embedding biomarkers within the hair shaft as it grows. When sampled near the scalp, hair can offer detection for up to approximately three months for both alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient to transport.

A segment measuring 1.5 inches of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, an optimal amount for testing purposes. For EtG, add-ons, or when testing beyond 10 panels, 150mg is suggested. Using a jeweler’s scale is recommended for precise measurement. If scalp hair is unavailable, a similar quantity of body hair may be utilized. "Head hair" corresponds to scalp hair exclusively, whereas "body hair" applies to any other types (e.g., facial, axillary).

Process Overview

The procedure for lab testing of a drug sample consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial intake of a sample into a lab’s workflow. It involves confirming that the specimen was properly sealed and transported, generating a unique LAN (Laboratory Accessioning Number), and performing any required data entry supplementary to an electronic tracking system.

Screening serves as a preliminary evaluation to detect drug abuse. Although Screening is an affordable way to eliminate drug use in most samples, a positive screen must undergo confirmation to be legally defensible. Any samples with potential positive results from Screening need further verification.

When a specimen shows potential positivity in Screening, additional hair is extracted from the original sample and processed for Extraction. This phase extracts substances from hair at lower concentrations than other methods (e.g., urine or saliva), which makes hair drug testing highly complex.

Confirmation of positive findings is performed using GC/MS, GC/MS/MS, or LC/MS/MS technology. All samples with presumptive positives undergo washing before confirmation if necessary. The complete lab testing process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing identifies drug use for up to 90 days, unlike urine testing, with its shorter detection range.
• Challenging to manipulate: The difficulty in tampering with hair drug tests enhances result integrity.
• Offers chronological data: It outlines a timeline of substance use over time, not merely recent consumption.

Limitations:

• Incapable of identifying recent consumption: Drugs become detectable in hair after 5-7 days.
• Expense: Hair drug testing tends to be costlier compared to other testing approaches.
• Result variability: Aspects such as hair color and individual growth differences can influence drug metabolite levels in hair.

Note: The term "hair follicle tests" is often used, though the test actually examines the hair shaft and not the follicle beneath the scalp.
