Hair Follicle Drug Testing - Wilson, MN

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by capturing biomarkers within the strands of growing hair. When obtained near the scalp, hair can offer up to a 3-month detection period for alcohol and other substances. Hair is straightforward to gather, somewhat challenging to tamper with, and simple to transport.

A 1.5-inch portion consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp will yield 100mg of hair, the optimal quantity for analysis and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler's scale to measure the specimen. If scalp hair isn't accessible, an equivalent amount of body hair can be acquired. When discussing head hair, we mean only scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The key steps in the lab handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial intake of a sample into a lab’s system. This process includes confirming that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and filling any supplementary data entry absent in an electronic chain of custody system.

Screening is an initial rapid check for substances of abuse. While Screening is a cost-effective method to dismiss drug usage in the majority of samples, a screen that turns out positive needs confirmation for court acceptance. Any samples that are presumptively positive in Screening necessitate a secondary confirmation.

If a sample appears presumptively positive during the Screening phase, more hair is extracted from the initial sample and readied for Extraction. Here, drugs are extracted from hair at a considerably lower concentration compared to other methods (such as urine or oral fluid), which explains why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening finding is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is inspected under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a more limited detection period.
• Difficult to manipulate: Cheating a hair drug test is very challenging, thus making the results more reliable.
• Offers historical insight: It provides a pattern of drug usage over time, not merely recent use.

Limitations:

• Incapable of detecting recent use: Drugs take around 5-7 days to be detectable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing methods.
• Results variability: Factors including hair color and personal hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Frequently referred to as "hair follicle tests," the test itself analyzes the hair strand, rather than the hair follicle beneath the scalp.
