Hair Follicle Drug Testing - Dunlap, IA

What it is, How it works

Hair analysis is increasingly regarded as an effective means for identifying drug and alcohol consumption. With its ability to encapsulate biomarkers within the fibers of emerging strands, hair offers an extended timeline for detecting substances. A sample taken from near the scalp can reveal drug or alcohol use over an approximate three-month span. Collecting hair is straightforward, challenging to tamper with, and effortless to transport.

Obtaining a 1.5-inch segment of around 200 hair strands from closest to the scalp results in 100mg of hair, which is the ideal amount for both initial and confirmed analysis. For EtG, additional analyses, or examinations exceeding 10 panels, a sample of 150mg is suggested. We advise measuring the sample on a jeweler's scale. In the absence of scalp hair, a comparable quantity of body hair can be used. "Head hair" denotes only hair from the scalp, while "body hair" encompasses all other hair types including facial and axillary hair.

Process Overview

There are four key stages in a laboratory's drug testing procedure: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a lab's processing system. This involves verifying proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional information missing from an electronic chain of custody system.

Screening offers an initial rapid evaluation for illicit substances. While screening serves as a cost-effective measure to dismiss most samples' drug use, a confirmed test result is necessary for legal proceedings. Presumptive positives identified during screening will require a subsequent confirmation step.

Should a sample test presumptively positive during the Screening stage, further hair is extracted from the original sample to prepare for Extraction. This phase involves extracting drugs from hair at concentrations lower than those found through other testing methods (e.g., urine or oral fluid), making hair drug testing uniquely challenging.

Positive screening confirmations are executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation if necessary. The entire laboratory process, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the ability to detect drug usage over a 90-day span, contrasting with the shorter detection window of urine tests.
• Challenging to evade: Cheating a hair drug test is exceedingly difficult, ensuring greater result accuracy.
• Supplies historical insights: These tests offer a comprehensive overview of patterns of drug use collected over time, rather than just recent activity.

Limitations:

• No recent use detection: Drug traces only become localized in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests generally present a higher cost compared to other testing approaches.
• Result variability: Elements such as hair color and personal differences in hair growth may impact drug metabolite concentrations within hair.

Note: Commonly labeled as "hair follicle tests," these evaluations scrutinize the hair strand itself, not the underlying hair follicle beneath the scalp.
