Hair Follicle Drug Testing - Londonderry, VT

What it is, How it works

Viewing hair testing as a potent method for identifying drug and alcohol consumption has become prevalent. Hair strands capture biomarkers within the growing fiber, offering a comprehensive account of alcohol and drug intake over time. Collecting hair close to the scalp can reveal substance use spanning up to three months. Hair collection is straightforward, resists tampering, and is easily transportable.

Gathering a 1.5-inch length with approximately 200 strands of hair (comparable to a #2 pencil) nearest to the scalp yields 100mg, which is optimal for evaluation and validation. For EtG, add-ons, and/or assessments beyond 10 panels, a 150mg sample is suggested. It’s advisable to weigh the sample using a jeweler's scale. In the absence of scalp hair, a similar volume of body hair might be used. When discussing head hair, it pertains specifically to scalp hair. Body hair encompasses other types, such as facial or axillary.

Process Overview

Four primary steps constitute the laboratory processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the start of a sample's integration into the lab's system, ensuring correct sealing and shipment, generating a unique LAN (Laboratory Accessioning Number), and performing any extra data tasks not managed by an electronic chain of custody.

Screening offers a rapid initial assessment for drug presence, serving as an economical means to dismiss drug use in many cases, but positive screenings necessitate validation for legal admissibility. Samples flagged as potentially positive require secondary confirmation.

If potential positivity is identified during Screening, additional hair is extracted from the initial sample for Extraction. This phase involves drug extraction at notably lower concentrations than in other tests (like urine or oral fluids), thus making hair drug testing particularly challenging.

Confirmation of positive results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples tentatively positive undergo necessary cleansing prior to confirmation. The entire processing chain from Accessioning through Confirmation meets CAP (College of American Pathologists) Hair designation requirements and aligns with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair tests have the capability to identify drug usage up to 90 days, unlike urine tests which offer a shorter period.
• Difficulty to cheat: Cheating a hair test proves extremely challenging, enhancing result reliability.
• Provides historical data: It captures a drug use timeline, indicating past usage patterns instead of recent incidents only.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair after roughly 5-7 days.
• Cost: Generally, hair drug testing costs surpass those of other methods.
• Variations in results: Drug metabolite concentration in hair may vary with hair color and individual hair growth rates.

Note: Although termed as "hair follicle tests," the actual analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Londonderry, VT, the reasons hair follicle drug tests surpass urine tests are manifold. Unlike urine screening, hair testing is not easily cheated, ensuring much higher reliability. Furthermore, hair tests boast precision, picking up even low-level drug use that urine tests might overlook due to their limited detection window and vulnerability to sample tampering.

Comparing the two methodologies, hair testing's advantage lies in the longer window of detection and its resistance to tampering. Urine tests are typically only effective for recent drug usage, whereas hair tests, with their sophisticated analysis, provide insights into a person's drug usage patterns over a substantial period, making it the preferred choice for employers and legal entities.

Extended Detection Window

Hair follicle tests in Londonderry, VT, are renowned for their extended detection window, offering analysis of drug use up to 90 days prior. This makes them extremely useful for employers seeking a comprehensive view of a potential hire's drug history.

By using hair samples, which keep a record of drug exposure for a considerable period, businesses can gain a detailed picture of an individual’s substance habits. This extended window surpasses the capabilities of urine tests, making hair testing a valuable tool for systematic substance monitoring.

Tamper-Resistant Testing Method

In Londonderry, VT, hair follicle tests are recognized for their resistance to tampering, offering peace of mind with reliable results. Unlike urine samples, which can be easily adulterated, hair samples hold evidence of drug use that tampering cannot alter.

This integrity in the testing process ensures credibility in the results, imperative for employers who rely on these reports to make informed decisions.
