Hair Follicle Drug Testing - Lexington, IN

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. The fibers in hair strands capture biomarkers, providing a comprehensive historical record of alcohol and drug use. When hair is cut near the scalp, it can reveal approximately three months' worth of drug and alcohol history. This method is straightforward to collect, challenging to tamper with, and convenient to transport.

To obtain an optimal sample for both initial screening and subsequent confirmation, a 1.5-inch segment consisting of roughly 200 hair strands (comparable in size to a #2 pencil) closest to the scalp is recommended, yielding about 100mg of hair. For tests exceeding 10 panels or including EtG add-ons, it's advised to collect 150mg of the sample. Utilizing a jeweler's scale for weighing is recommended. If scalp hair is not available, an equivalent quantity of body hair may be used. References to head hair pertain specifically to scalp hair, while body hair encompasses all other types (like facial or axillary hair).

Process Overview

Laboratory drug testing typically involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes an initial process to integrate it into the laboratory's system. This includes ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not captured by an electronic chain of custody system.

Screening provides an initial fast assessment for substances of abuse. Although Screening serves as a cost-efficient means to dismiss drug use in most samples, a positive result in this phase needs validation to be legally permissible. Any samples that test presumptively positive during Screening require further confirmation.

Samples testing presumptively positive during Screening have more hair extracted from the original sample for the Extraction phase. In this phase, hair drug screening faces the challenge of extracting drugs from hair at lower concentrations compared to other methods (e.g., urine or oral fluid).

Confirmation for any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed prior to confirmation, if required. The entire lab process from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests with shorter timelines.
• Reduced risk of falsification: The difficulty in manipulating hair drug tests results increases accuracy.
• Historical consumption pattern: Provides an overview of drug use over time, beyond recent consumption.

Limitations:

• Recent use detection not possible: Drugs become detectable in hair about 5-7 days post-use.
• Higher cost: Hair drug tests tend to be more costly than other testing methods.
• Variable outcomes: Factors such as individual hair growth and color can influence drug metabolite concentration in hair.

Note: Although often labeled as "hair follicle tests," the test evaluates the hair strand rather than the follicle beneath the scalp.
