Hair Follicle Drug Testing - Williamsburg, MI

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and other substances by embedding biomarkers in the growing hair fibers. When sourced close to the head, hair offers a detection period for up to about three months for alcohol and various drugs. Hair is easy to gather, relatively challenging to tamper with, and convenient to ship.

A 1.5-inch portion consisting of approximately 200 hair strands (roughly equivalent to a #2 pencil) nearest to the scalp can yield 100mg of hair, which is the optimal sample for both screening and verification. For EtG, supplementary tests, and/or examinations over 10 panels, 150mg of the sample is advisable. It is suggested to weigh the specimen using a jeweler's scale. If scalp hair cannot be obtained, a similar quantity of body hair may be utilized. In terms of head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result primarily comprises four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial inclusion of a sample into a lab's system. This step involves ensuring the sample is sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and filling in any extra data not available via an electronic chain of custody.

Screening is a preliminary rapid test for substances of abuse. While it's a cost-efficient method to dismiss drug usage in most samples, a positive screen necessitates confirmation for court acceptance. Samples that show a presumptive positive in Screening need confirmation through further testing.

Should a sample indicate a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction process. In this phase, drugs are retrieved from hair at a significantly finer concentration compared to other techniques (e.g., urine or oral fluid), which renders hair drug screening the most complex methodology to execute.

Confirmation of any positive screening outcome is done via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as required. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair tests can track drug use up to 90 days, as opposed to urine tests, which have a shorter detection period.
• Hard to manipulate: Cheating on a hair drug test is quite difficult, leading to more precise results.
• Reflects historical consumption: Offers a pattern of drug use over time, rather than just recent usage.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair in about 5-7 days.
• Expense: Hair drug tests are typically pricier than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Frequently termed as "hair follicle tests", the actual test examines the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing
