Hair Follicle Drug Testing - Saint Hilaire, MN

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair preserves a comprehensive record of alcohol and other substances by embedding biomarkers within the fibers as the hair grows. A sample taken near the scalp can offer a detection timeframe of up to roughly three months for alcohol and various drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

An ideal sample for screening and confirmation consists of a 1.5-inch portion of around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp, providing 100mg of hair. For EtG, additional tests, or panels exceeding ten, a specimen of 150mg is advised. Utilizing a jeweler's scale for weighing the sample is suggested. If scalp hair is not available, an equivalent quantity of body hair can be gathered. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning involves the initial integration of a sample into a lab's system. This includes ensuring the sample was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody.

Screening provides a preliminary examination for substances. While it is a cost-effective means to exclude drug use in the majority of cases, positive screenings must be confirmed to be legally valid. Any samples with presumptive positive results in Screening require secondary confirmation.

If Screening yields a presumptive positive, additional hair is extracted from the initial specimen and prepped for Extraction. At this stage, drugs are separated from hair at much lower concentrations than with other methods (such as urine or oral fluid), making hair drug screening a complex technique.

Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can ascertain drug use up to 90 days, whereas urine tests have a more limited detection period.
• Reduced likelihood of tampering: Cheating a hair drug test is notably difficult, ensuring more reliable results.
• Tracks historical usage: It outlines drug consumption patterns over time, not merely recent use.

Limitations:

• Incapable of detecting recent usage: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests typically incur higher costs compared to other methods.
• Result variability: Attributes like hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Despite being termed as "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp.
