Hair Follicle Drug Testing - Tschetter Colony, SD

What it is, How it works

Hair testing is recognized as a key method for identifying drug and alcohol consumption. Hair captures long-term exposure to alcohol and drugs by embedding biomarkers within the fibers of the growing hair. When taken close to the scalp, hair testing can reveal drug and alcohol use over a three-month period. Hair sampling is straightforward to perform, challenging to tamper with, and easy to transport.

A sample measuring 1.5 inches, roughly equating to the size of a #2 pencil and composed of about 200 strands, will yield approximately 100mg of hair, an ideal amount for both screening and confirmation. For EtG tests, additional analyses, and tests exceeding ten panels, a sample of 150mg is suggested. It's advisable to weigh specimens on a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair may be obtained. References to head hair specifically indicate scalp hair. Body hair includes all other hair types (such as facial and axillary hair).

Process Overview

The laboratory processing of drug test results is comprised of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step, involving the intake of a sample into a laboratory's system. This step ensures the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any additional data entry not covered by an electronic chain of custody protocol.

Screening is a preliminary evaluation for potential drug abuse. Although Screening is economical and can identify drug use in most samples, results that test positive must be verified for legal admissibility. Samples yielding a presumptively positive result during Screening require a secondary confirmation.

A sample testing presumptively positive in Screening undergoes further hair extraction from the initial batch for the Extraction phase. Here, drugs are extracted from hair at a lower concentration compared to other methods like urine or saliva testing, making hair drug testing particularly complex.

Confirmation of positive screening outcomes uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed when needed before confirmation. The entire process, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use over a 90-day span, whereas urine tests have shorter detection durations.
• Increases testing reliability: Hair drug tests are difficult to manipulate, ensuring more accurate results.
• Offers historical patterns: This can illustrate a drug use pattern over time, rather than recent consumption alone.

Limitations:

• Lacks in detecting immediate usage: Drugs typically require 5-7 days to be traceable in hair.
• Expense: Hair drug tests tend to be more costly compared to other testing options.
• Result variability: Factors like hair color and individual hair growth can impact drug metabolite levels in hair.

Note: While often called "hair follicle tests," the procedure analyzes the hair strand itself rather than the follicle beneath the scalp.
