Hair Follicle Drug Testing - Trenton, IA

What it is, How it works

Hair testing has increasingly become recognized as an effective approach for identifying drug and alcohol consumption. The growing strands of hair capture biomarkers, offering a detailed overview of alcohol and other substance use over an extended period. When hair is harvested near the scalp, it can furnish roughly a 3-month timeframe for detecting these substances. The collection process is straightforward, the possibility of tampering is minimal, and shipping is convenient.

An optimal test sample consists of a 1.5-inch segment of roughly 200 hair strands (roughly resembling a #2 pencil in size) from the scalp, providing approximately 100mg of hair for screening and confirmation. For EtG, additional tests, and panels exceeding 10, a 150mg sample is advisable. Utilizing a jeweler’s scale for weighing the specimen is recommended. If scalp hair cannot be obtained, a comparable quantity of body hair can be sourced. References to head hair specifically indicate scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The key phases in the laboratory's drug test processing include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially introduced into a lab's system. This phase ensures the sample’s seal and shipment were intact, assigns a random LAN (Laboratory Accessioning Number), and completes any residual data input not handled by an electronic chain of custody system.

Screening delivers an initial assessment for substances of abuse. Although it is a budget-friendly method to eliminate drug use in most samples, a positive Screening result demands confirmation to hold legal weight. Samples that appear positive during Screening require further confirmation.

Upon receiving a presumptively positive result in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from hair at much lower concentrations compared to other methods (like urine or oral fluid), which makes hair drug testing particularly challenging.

The Confirmation phase for any positive Screening result involves GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all samples with presumptive positives undergo washing as needed. From Accessioning through Confirmation, the entire laboratory process is thoroughly vetted under the College of American Pathologists (CAP) Hair designation and meets the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can track drug usage up to 90 days, offering a wider detection window compared to urine tests.
• Difficult to manipulate: Hair drug testing minimizes the chances of fraudulent results, enhancing accuracy.
• Provides usage history: It not only detects recent use but also offers an extensive pattern of drug activity over time.

Limitations:

• Cannot immediately detect recent use: There’s a 5-7 day delay before drugs become detectable in hair.
• Expense: Hair drug tests tend to be pricier than other testing techniques.
• Result variability: Factors such as hair color and individual variations in hair growth can influence drug metabolite concentration in hair.

Note: Although commonly referred to as "hair follicle tests", the analysis targets the hair strand itself, not the follicle beneath the scalp.
