Hair Follicle Drug Testing - Homestead, IA

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol use. Hair strands capture biomarkers within the fibers, offering a comprehensive long-term record of substances. When collected from near the scalp, hair testing furnishes an approximate 3-month detection period for drugs and alcohol. The procedure for collecting hair is straightforward, relatively tamper-resistant, and convenient to transport.

A 1.5-inch segment, containing around 200 strands (comparable to a #2 pencil in diameter), yields 100mg of hair, the optimal sample volume for both screening and confirmation purposes. For EtG tests, additional add-ons, and/or tests exceeding a 10-panel screening, a larger portion of 150mg is advisable. Utilizing a jeweler’s scale for measurement is suggested. In the absence of scalp hair, equivalent quantities of body hair can be considered. The term "head hair" exclusively refers to scalp hair, in contrast to "body hair," which pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of drug test samples encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase wherein a sample is logged into the lab's database. This phase ensures the sample is securely sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and involves completing any supplementary data entry tasks not managed by an electronic chain of custody system.

Screening provides an initial assessment of samples for potential substance abuse. While this cost-effective approach can exclude drug use in most cases, a positive screening outcome necessitates additional confirmation for legal standing. Samples indicating a presumptive positive in Screening undergo subsequent verification.

In cases where the Screening results are presumptively positive, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated at significantly reduced concentrations than in other testing methods (such as urine or oral fluid), making hair testing the most challenging methodology to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples are treated via washing before confirmation as required. The laboratory workflow, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can reveal drug use for as long as 90 days, unlike urine tests, which have more limited detection spans.
• Resistant to falsification: The difficulty of tampering with hair drug tests enhances result accuracy.
• Historical insight: It provides a comprehensive pattern of drug use over time rather than indicating only recent use.

Limitations:

• Inability to detect recent use: Approximately 5-7 days are required for drugs to become traceable in hair.
• Expense: Hair drug testing typically incurs greater costs than alternate testing methodologies.
• Result variability: Factors such as hair color and individual hair growth differences may influence drug metabolite concentrations in hair.

Note: Commonly referred to as "hair follicle tests," the actual assessment focuses on the hair strand, not the follicle beneath the scalp.
