Hair Follicle Drug Testing - Spicer, MN

What it is, How it works

The analysis of hair has emerged as an effective method for identifying drug and alcohol consumption. By capturing biomarkers in the hair strand's growing fibers, hair provides an extensive record of alcohol and other drugs. Collected close to the scalp, hair samples can reveal up to a three-month substance use timeline for alcohol and drugs. Hair collection is straightforward and challenging to tamper with, plus it's convenient to transport.

Gathering a 1.5-inch portion consisting of roughly 200 hair strands, akin in size to a #2 pencil, near the scalp yields around 100mg of hair—ideal for both preliminary and confirmatory testing. For EtG tests, expanded panels, and analyses exceeding 10 panels, a 150mg sample is advisable. It's best to use a jeweler's scale to weigh the sample. If scalp hair isn't accessible, the equivalent amount of body hair can be utilized. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other hair variations (facial, axillary, etc.).

Process Overview

The laboratory workflow for processing a drug test outcome includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase where a sample is introduced into a lab's system. It involves confirming the sample's proper sealing and transport, generating a random LAN (Laboratory Accessioning Number), and completing any extra data input not captured by an electronic chain of custody system.

Screening serves as an initial swift assessment for substances of concern. While Screening offers an economical approach to discount drug use for most samples, a positive screen requires further validation for legal proceedings. Samples indicating presumptive positivity in Screening necessitate follow-up confirmation.

A presumptive positive sample in the Screening phase leads to extracting additional hair from the original specimen for the Extraction step. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), hence, hair drug testing presents greater complexity.

For confirming any positive screening result, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples with presumptive positivity undergo necessary washing before Confirmation. The comprehensive laboratory stages from Accessioning to Confirmation are scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for up to 90 days, unlike urine tests that have a shorter detection span.
• Challenging to evade: Manipulating a hair drug test is notably difficult, enhancing result accuracy.
• Supplies historical insight: The test can illustrate a drug use pattern over time, rather than just recent consumption.

Limitations:

• Incapable of identifying recent consumption: A period of 5-7 days is required for drugs to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than other drug screening techniques.
• Result variability: Elements such as hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Often termed "hair follicle tests," the analysis actually examines the hair strand, not the follicle beneath the scalp.
