Hair Follicle Drug Testing - Centreville, MI

What it is, How it works

The utilization of hair testing has emerged as an effective instrument for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and drug use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer an approximate 3-month period for detecting alcohol and drug presence. Additionally, hair collection is straightforward, relatively resistant to tampering, and convenient for transport.

A 1.5-inch section comprising roughly 200 strands (approximately a #2 pencil's thickness) near the scalp produces 100mg of hair, which is the preferred amount for assessment and verification. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg sample is advisable. It is suggested to measure the sample using a jeweler’s scale. If scalp hair cannot be collected, a comparable quantity of body hair may be used. References to head hair pertain solely to scalp hair, while body hair includes all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the initial handling of a sample upon entering a laboratory’s workflow. This process verifies proper sealing and dispatch of the sample, designates a random LAN (Laboratory Accessioning Number), and attends to any additional data entry absent from an electronic chain of custody system.

Screening entails an initial cursory evaluation for substance abuse. While Screening offers a cost-efficient approach to eliminate drug consumption for most samples, confirmation is necessary for a positive screen to be legally viable. Samples yielding a presumptive positive in Screening necessitate further confirmation.

Should a sample indicate presumptive positivity during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at a notably lower concentration than in alternative methods (e.g., urine or oral fluid), underpinning why hair drug testing is the most challenging methodology to execute.

Confirmation of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to necessary confirmation. The comprehensive laboratory process, spanning from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can recognize drug use for up to 90 days, unlike urine tests with a briefer detection span.
• Challenge to deceive: It is exceedingly challenging to subvert a hair drug test, enhancing result accuracy.
• Offers historical insight: It can reveal a pattern of drug consumption over time, as opposed to only recent usage.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug analyses generally incur higher costs than other testing methods.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests", the analysis pertains to the hair strand rather than the follicle beneath the scalp.
