Hair Follicle Drug Testing - Gregory, KY

What it is, How it works

Hair analysis has emerged as an effective means to detect substance and alcohol consumption. Hair captures a comprehensive history of substances by embedding biomarkers in the strands of growing hair. When taken near the scalp, this method offers a detection window of up to around three months for alcohol and other substances. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.

A 1.5-inch clipping of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the perfect sample size for both screening and confirmation. For testing EtG, additional assessments, and tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair isn't present, an equivalent quantity of body hair might be utilized. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types such as facial and axillary hair.

Process Overview

There are four primary phases in the laboratory handling of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first procedure of inducting a sample into a lab’s system. This step verifies that the sample was securely sealed and forwarded correctly, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary rapid assessment for drug abuse. While it's a budget-friendly approach to rule out drug consumption in most samples, any positive screening must be verified to be court-admissible. All samples that appear positive during Screening require secondary confirmation.

If a sample seems positive at the Screening stage, additional hair is taken from the original specimen for Extraction. During Extraction, substances are isolated from hair at a significantly lower concentration than in alternate methodologies (such as urine or oral fluid), which makes hair drug testing the most challenging methodology to conduct.

Confirmation of any positive results from Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as warranted. The overall laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can unveil drug use up to 90 days, whereas urine tests have a more limited detection timeframe.
• Hard to deceive: Modifying results is very difficult, thus enhancing accuracy.
• Historic usage data: Offers insights into substance use patterns over time, not only recent consumption.

Limitations:

• Inability to identify recent use: Detecting drugs in hair typically takes 5-7 days.
• Expense: Hair drug testing tends to be costlier than other testing methods.
• Result variability: Drug metabolite concentration in hair can vary due to hair color and personal hair growth differences.

Note: Commonly mentioned as "hair follicle tests", the analysis is performed on the hair strand, not the follicle beneath the scalp
