Hair Follicle Drug Testing - Avoca, IA

What it is, How it works

Hair assessments have emerged as an effective method for uncovering drug and alcohol consumption. Hair captures long-term drug and alcohol histories by embedding biomarkers within the growing hair strand's fibers. When gathered close to the scalp, hair provides a detection timeframe of up to approximately 3 months for alcohol and other substances. It's straightforward to collect, hard to tamper with, and convenient to send.

A 1.5-inch specimen of roughly 200 hair strands (comparable to the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is optimal for examination and corroboration. For EtG, additional testing, and/or panels exceeding 10, 150mg of the sample is recommended. Using a jeweler’s scale, we suggest weighing the sample. If scalp hair is inaccessible, a similar amount of body hair can be used. Head hair refers exclusively to scalp hair, while body hair encompasses all other hair types (such as facial and axillary).

Process Overview

The laboratory handling of a drug test outcome involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial integration into a laboratory’s system. This process ensures the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any pending data entry absent from an electronic chain of custody system.

The Screening phase quickly checks for drug abuse presence. Screening offers an economical way to dismiss drug use in the majority of specimens, but any positive result requires confirmation to be court-admissible. Samples testing presumptively positive during Screening necessitate subsequent validation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at concentrations significantly lower than those in other methodologies (e.g., urine or oral fluid), underscoring why hair drug examination remains the most challenging technique.

Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing prior to verification if required. The entire laboratory sequence from Accessioning through to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and adheres to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests which provide a shorter timeframe.
• Testing fidelity: Cheating a hair drug test is highly challenging, thus enhancing result reliability.
• Demonstrates usage trends: It offers a record of substance use over time, not merely recent use.

Limitations:

• Inability to detect recent ingestion: Detectability of drugs in hair typically starts 5-7 days post-use.
• Expense: Hair drug evaluations are generally pricier than alternative drug testing methods.
• Result variability: Variables like hair color and personal hair growth differences can influence the concentration of drug metabolites in hair.

Note: Although frequently termed "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle beneath the scalp.
