Hair Follicle Drug Testing - Oak Park, MI

What it is, How it works

Hair analysis is increasingly recognized as an effective means of detecting drug and alcohol consumption. Hair serves as a long-term record of substance intake by embedding biomarkers within the fibers of the developing hair strand. When samples are taken close to the scalp, they can offer up to around a 3-month window of detection for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

Gathering a 1.5-inch segment, approximately consisting of 200 hairs (similar in size to a #2 pencil) from the scalp yields 100mg, the optimal quantity for testing and verification. For EtG, additional analyses, and/or panels beyond 10, 150mg of hair is advised. A jeweler’s scale is recommended for weighing the sample. If scalp hair isn't available, a similar amount of body hair can be obtained. When mentioning head hair, we refer to scalp hair exclusively. Body hair includes all other hair types (e.g. facial, axillary).

Process Overview

The laboratory handling of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a lab's workflow. This involves confirming that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry not covered by an electronic chain of custody system.

Screening provides a preliminary check for substances of abuse. While Screening is economical for excluding drug use in most samples, a positive result requires verification to be valid in legal settings. Any samples testing positive in Screening necessitate further confirmation.

If Screening suggests a positive result, additional hair is drawn from the original specimen and readied for Extraction. This phase involves extracting drugs from hair at a significantly lower concentration than other methods (such as urine or oral fluid), making hair drug testing the most complex methodology to execute.

Confirmation of any positive Screen is performed with GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can detect drug use for up to 90 days, unlike urine tests with shorter windows.
• Hard to manipulate: Cheating a hair test is quite difficult, ensuring more accurate results.
• Shows usage patterns: It reveals a drug use history over time, unlike recent use only.

Limitations:

• Not for recent detection: It takes about 5-7 days for drugs to become detectable in hair.
• Cost factor: Hair drug tests generally cost more than other methods.
• Result variability: Hair color and personal growth differences can impact metabolite levels in hair.

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