Hair Follicle Drug Testing - Peru, VT

What it is, How it works

Hair testing has emerged as a robust method to identify drug and alcohol consumption. By embedding biomarkers within the strands of growing hair, it supplies an extended history of substance use. When secured near the scalp, hair can reveal alcohol and drug presence for about a 3-month duration. Hair is easy to acquire, fairly resistant to tampering, and simple to transport.

Obtaining a 1.5-inch snippet consisting of roughly 200 hair strands (comparable to a #2 pencil's diameter) near the scalp yields 100mg of hair, which is optimal for testing and verification. For EtG, extra tests, or those beyond 10 panels, 150mg of the sample is suggested. It's advisable to measure the sample with a jeweler’s scale. Should scalp hair be sparse, an equivalent amount of body hair can be used. By head hair, we mean only the scalp hair. Body hair encompasses all other types (facial hair, armpit hair, etc.).

Process Overview

The laboratory processes a drug test result through four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample into a laboratory’s system. This step includes verifying the sample's seal and shipment, assigning a unique LAN (Laboratory Accessioning Number), and filling out any additional info not covered by an electronic chain of custody system.

Screening provides an initial rapid check for drug abuse. Screening is cost-effective for eliminating drug usage in most samples, though a positive screen must be confirmed for court eligibility. Any sample tentatively positive in Screening merits a follow-up confirmation.

In cases of tentative positive results during Screening, additional hair is extracted from the original sample and prepared for Extraction. Drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine, oral fluid), marking hair drug screening as a particularly challenging technique to execute.

GC/MS, GC/MS/MS, or LC/MS/MS techniques validate any positive screening outcomes. All presumptive positive samples are cleansed before confirmation as deemed necessary. From Accessioning to Confirmation, the lab process is examined under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Long detection window: Hair testing can reveal substance use for up to 90 days, unlike urine testing which has a more limited detection period.
• Resistance to falsification: Hair drug testing is difficult to manipulate, ensuring more reliable results.
• Provides a history of consumption: It can indicate a usage pattern spanning several months, not merely recent usage.

Limitations:

• Unable to detect recent usage: Drugs become traceable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Result variability: Factors like hair color and unique hair growth differences can influence the concentration of drug metabolites in hair.

Note: Although commonly known as "hair follicle tests", the analysis is performed on the hair strand itself, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Peru, VT, hair follicle testing offers a superior alternative to urine tests by providing unmatched detection accuracy. This method captures a longer history of substance use, making it more comprehensive than urine tests. While urine tests detect recent use, hair testing reveals patterns up to 90 days back.

Hair follicle testing's reliability stems from its ability to detect a broader spectrum of substances with fewer false negatives. This ensures more precise and reliable results for those implementing drug-free policies in a workplace setting.

Extended Detection Window

Hair follicle testing in Peru, VT, offers the advantage of an extended detection window, which can capture evidence of drug use up to 90 days prior. This comprehensive view enables employers to gain better insight into an individual's long-term substance use behavior.

The extended detection period provided by hair follicle tests allows companies and testing agencies to understand substance use trends, unequaled by methods that only offer short-term detection, such as urine tests.
