Hair Follicle Drug Testing - Goldonna, LA

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance usage by embedding biomarkers within its strands as it grows. When sampled close to the scalp, hair can offer a detection window of about three months for these substances. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment comprising about 200 hair strands (similar to the diameter of a #2 pencil) near the scalp yields 100mg of hair, an optimal quantity for both initial screening and confirmatory testing. For EtG, additional analyses, or tests beyond 10 panels, a specimen of 150mg is advisable. It is suggested to measure the specimen using a jeweler’s scale. In cases where scalp hair is unavailable, an equivalent quantity of body hair can be utilized. References to head hair specifically mean scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning involves initially inputting a sample into a laboratory’s system, which includes confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any additional data entry not covered by an electronic chain of custody system.

Screening serves as an introductory check for frequently abused drugs. While cost-effective in ruling out drug use for most samples, a positive screen requires confirmation for legal validity. Any samples that yield a presumptive positive in Screening necessitate further confirmation.

If a specimen appears positive in the Screening phase, additional hair is extracted from the original sample for the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as required. Throughout the laboratory process—from Accessioning to Confirmation—each step is examined under the CAP (College of American Pathologists) Hair criteria and adheres to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can trace drug usage for up to 90 days, unlike urine tests which provide a shorter detection timeframe.
• Hard to manipulate: It's exceptionally challenging to deceive a hair drug test, thus enhancing the accuracy of results.
• Historical insight: It offers a record of substance use over time, rather than just recent consumption.

Limitations:

• Limited in detecting recent use: Drugs become detectable in hair approximately 5-7 days following intake.
• Costly: Hair drug tests typically incur higher expenses than alternative testing methods.
• Variable outcomes: Factors such as hair color and individual differences in hair growth may influence drug metabolite levels in hair.

Note: Often called "hair follicle tests," the test actually examines the hair shaft, not the follicle beneath the scalp.
