Hair Follicle Drug Testing - Delphi, IN

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug intake by embedding biomarkers in the fibers of the hair strand as it grows. When obtained near the scalp, hair can offer approximately a 3-month detection period for alcohol and drugs. Hair is straightforward to collect, relatively hard to alter, and convenient to ship.

A 1.5-inch sample consisting of about 200 hair strands (roughly the width of a #2 pencil) near the scalp provides 100mg of hair, the optimal sample size for analysis and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, a comparable volume of body hair can be collected. The term head hair specifically refers to scalp hair only, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four primary steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial stage of incorporating a sample into the laboratory's system. This comprises confirming that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and executing any additional data entry absent from an electronic chain of custody system.

Screening constitutes a preliminary swift assessment for drugs of abuse. While it is a cost-effective method to exclude drug use in most samples, a positive result at this stage requires confirmation to be viable in legal contexts. Samples that are presumptively positive during Screening require subsequent confirmation.

For samples deemed presumptively positive at the Screening phase, further hair is extracted from the initial specimen and processed for Extraction. During this process, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS are employed to confirm any positive screening result. All samples presumed positive are cleansed before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage for up to 90 days, unlike urine tests which have a more limited detection period.
• Difficult to manipulate: Cheating a hair drug test is notably challenging, enhancing result accuracy.
• Chronological data available: It can offer a timeline of drug use over an extended period, rather than just recent intake.

Limitations:

• Inability to detect immediate use: Drugs generally require 5-7 days to become detectable in hair.
• Higher cost: Hair drug tests are often more costly compared to other drug testing techniques.
• Result variations: Elements such as hair color and individual hair growth differences can influence drug metabolite levels in the hair.

Note: While sometimes described as "hair follicle tests", the focus is on analyzing the hair strand rather than the follicle beneath the scalp.
