Hair Follicle Drug Testing - St. Hilaire, MN

What it is, How it works

Hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair serves to record a prolonged history of substance use by embedding biomarkers within the hair shaft as it grows. When hair is cut close to the scalp, it can present an approximate three-month detection timeline for substances. The collection process for hair is straightforward, has a lower risk of tampering, and facilitates easy transportation.

An optimal 1.5-inch sample, containing roughly 200 hair strands (akin to the girth of a #2 pencil) near the scalp delivers 100mg, ideal for initial testing and confirmation. For EtG, additional screenings, or tests exceeding ten panels, 150mg of hair should be used. We suggest assessing the hair's weight using a jeweler's scale. If scalp hair isn't available, a comparable quantity of body hair can be collected. 'Head hair' denotes scalp hair solely, whereas 'body hair' encompasses other types (facial, axillary, etc.).

Process Overview

The lab procedures for processing drug test results involve four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial integration of a sample into the lab's tracking system. This step verifies the correct sealing and shipment of the specimen, assigns a unique LAN (Laboratory Accessioning Number), and completes supplementary data entry absent from an electronic chain of custody system.

Screening performs an initial assessment for substances of abuse. This method is an economical alternative to exclude drug use in most specimens. However, a positive screen requires confirmation to meet court admissibility. Samples with a presumptive positive in Screening necessitate further confirmation.

In the event of a presumptive positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. This phase involves isolating drugs from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Positive screening results are confirmed by GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo cleansing pre-confirmation, when necessary. The full lab procedure, from Accessioning to Confirmation, is audited under the CAP (College of American Pathologists) Hair guidelines and accredited to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug use for up to ninety days, as opposed to the shorter detection span of urine tests.
• Low manipulation risk: Cheating a hair drug test is challenging, enhancing result reliability.
• Records usage patterns: It highlights drug usage trends over time, beyond immediate consumption.

Limitations:

• Cannot identify recent use: Drugs typically become traceable in hair around 5-7 days post-ingestion.
• Higher costs: Hair drug tests tend to be pricier than alternative drug testing approaches.
• Result variability: Variables such as hair pigmentation and individual hair growth rates can influence drug metabolite concentrations.

Note: Although often termed "hair follicle tests," the procedure actually examines the hair shaft rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers distinct advantages over traditional urine tests. In St. Hilaire, MN, this method more accurately captures prolonged substance use, ensuring comprehensive insights into an individual's habits. The ability of a hair test to identify drug use over an extended period gives it an edge for employers prioritizing thoroughness.

Compared to urine tests that only detect recent drug use, hair follicle tests provide superior detection covering up to 90 days. This wider detection period makes them invaluable for entities enforcing zero-tolerance policies. Trust the reliability of hair testing over the limitations of urine samples.

Extended Detection Window

One transformative benefit of hair follicle testing is its extended detection window. Employers in St. Hilaire, MN, can observe substance use habits spanning up to 90 days, offering a broad view of an individual's drug usage. This in-depth understanding is crucial for informed hiring and retention decisions.

Unlike short-term urine tests, hair follicle analysis captures long-term substance use, providing a definitive snapshot of an individual's history. This extended timeline allows for more strategically informed workplace decisions, favoring stability and safety.
