Hair Follicle Drug Testing - Geneva, MN

What it is, How it works

Hair analysis is now recognized as an effective means for detecting alcohol and drug consumption. The fibers of the growing hair strand traps biomarkers, making hair a repository for a prolonged history of alcohol and other drugs. When sampled near the scalp, hair can offer roughly a 3-month detection period for alcohol and other drugs. Collecting hair is straightforward, hard to tamper with, and easy to transport.

A 1.5-inch sample of around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for analysis and verification. For EtG, add-ons, and tests beyond 10 panels, 150mg of hair is advised. Utilizing a jeweler's scale to weigh the specimen is recommended. If scalp hair cannot be collected, a similar amount of body hair is an alternative. When referencing head hair, we mean scalp hair only. Body hair pertains to all other hair types (such as facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial entry of a sample into a laboratory's system. This process includes confirming the sample was properly sealed and shipped, generating a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening acts as an initial rapid assessment for substances of abuse. While Screening offers a cost-effective method to exclude drug use in most samples, a positive result requires confirmation for courtroom acceptance. Samples that yield a presumptive positive during Screening mandate secondary verification.

If a sample tests presumptively positive at the Screening phase, an additional portion of hair from the initial sample is taken and readied for Extraction. This phase involves extracting drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to conduct.

Any positive screening result is verified via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleaned as necessary. The entire process from Accessioning to Confirmation is inspected under the oversight of both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have a shorter detection timeframe.
• Difficult to deceive: Cheating on a hair drug test is extremely challenging, leading to more precise results.
• Historical usage data: It can reveal a usage pattern over time rather than just recent consumption.

Limitations:

• Incapable of detecting recent usage: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug testing typically incurs higher costs than other drug testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth may influence the concentration of drug metabolites within the hair.

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