Hair Follicle Drug Testing - Culberson, NC

What it is, How it works

Hair analysis has emerged as an effective method for identifying the consumption of drugs and alcohol. Hair offers an extended historical record of substance use by encapsulating biomarkers within the hairs as they grow. When hair is collected from the scalp, it can reveal a detection time frame of up to roughly three months for alcohol and drugs. The collection process for hair is straightforward, challenging to tamper with, and convenient for transport.

A sample measuring 1.5 inches, comprising approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, making it an optimal sample for both screening and confirming results. For EtG, additional tests, and/or tests beyond 10 panels, a 150mg sample is advisable. Using a jeweler’s scale for specimen measurement is suggested. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used instead. "Head hair" pertains solely to scalp hair, while "body hair" encompasses all alternate hair types (like facial or axillary hair).

Process Overview

There are four key stages in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory phase where a sample is integrated into the lab's system. This phase ensures the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not incorporated by an electronic chain of custody framework.

Screening is the preliminary rapid assessment for drugs of abuse. While cost-effective for ruling out drug use in most instances, a screening positive requires confirmation to be valid in legal settings. Any sample that yields a presumptive positive during the Screening phase necessitates follow-up confirmation.

When a sample shows a presumptive positive at the Screening stage, more hair is extracted from the initial sample for the Extraction phase. In this step, drugs are isolated from hair at considerably reduced concentrations compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.

To confirm any positive screening result, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples with presumptive positives undergo washing before undergoing confirmation if needed. The entire procedure from Accessioning through Confirmation is inspected under the standards of both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests detect drug use over a span of up to 90 days, whereas urine tests have a shorter detection duration.
• Difficulty to cheat: Cheating a hair drug test is exceedingly difficult, contributing to the accuracy of results.
• Provides historical data: Hair drug tests can illustrate a pattern of substance use over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: It takes about 5-7 days for substances to become traceable in hair.
• Cost: Hair drug tests typically cost more than alternative drug testing techniques.
• Variations in results: Elements like hair color and individual differences in hair growth can influence the level of drug metabolites detected in hair.

Note: Often called "hair follicle tests", the test analyzes the hair strand itself, not the follicle beneath the scalp.
