Accredited Drug Testing offers comprehensive hair follicle drug testing in Lock Haven, Pennsylvania. If you require a hair drug or alcohol test, Accredited Drug Testing excels in hair testing and operates testing centers in all cities nationwide that can conduct a hair test. Typically, 1.5 to 2 inches of hair from the crown or body is necessary. Hair tests can detect drugs, alcohol/ETG, or provide other tailored hair testing solutions.

In recent times, the approach to drug testing has increasingly incorporated the hair follicle drug test. Numerous employers, judicial bodies, and Substance Abuse specialists are opting for a hair drug test instead of a conventional urine test. Hair follicle drug tests are preferred by employers with zero-tolerance drug use policies, courts, and individuals on probation. The primary advantage of a hair follicle drug test includes a vastly extended detection window for drug use, reaching up to 90 days, collected through an observed collection process, and is nearly impossible to manipulate. However, for detecting drug use within the past 5 days, the urine test remains the most precise option.

What it is, How it works

Hair analysis has emerged as an effective means of detecting drug and alcohol consumption. Hair offers a longitudinal record of substance use by incorporating biomarkers into the structure of the growing hair. When taken from near the scalp, hair can reveal substance usage over a span of up to three months. Hair collection is straightforward, not easily tampered with, and convenient to transport.

A sample measuring 1.5 inches with roughly 200 strands (similar in size to a #2 pencil) taken nearest to the scalp yields 100mg, which is the optimal amount for testing and verification. For EtG, additional tests, or other tests beyond ten panels, 150mg is advisable. It’s suggested to weigh the hair on a jeweler’s scale. If scalp hair is absent, a comparable amount of body hair may be used. "Head hair" refers specifically to scalp hair, while "body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

The primary phases in laboratory evaluation of a drug test sample are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab's database. This process includes ensuring that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic custody system.

Screening entails a preliminary evaluation for substance use. Although screening is an economical approach to exclude drug use for most specimens, a confirmed screen is necessary for legal validity. Presumptive positive results from screening require subsequent confirmation.

For samples preliminarily positive at the Screening phase, additional hair is extracted from the initial sample for Extraction. In this process, substances are isolated from hair at much lower levels compared to methods like urine or saliva analysis, making hair drug testing a complex technique.

Any confirmed positive from Screening is validated through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are cleaned as needed before confirmation. The entire lab process from Accessioning through Confirmation is assessed under the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation.

Hair drug testing benefits:

  • Extended detection period: Hair tests can reveal drug use up to 90 days, exceeding the shorter timeframe of urine tests.
  • Resistance to tampering: Hair tests are difficult to falsify, ensuring more precise outcomes.
  • Historical insights: They reflect a timeline of substance use rather than just recent activity.

Drawbacks:

  • Inability to detect recent use: Detection in hair takes around 5-7 days post-use.
  • Higher costs: Hair analysis is pricier compared to other testing approaches.
  • Result variability: Hair color and personal growth rates can influence drug metabolite levels in hair.

Note: Referred to as "hair follicle tests", the actual analysis is of the hair strand, not the hair follicle beneath the surface.

Why Hair Follicle Testing Beats Urine Testing

In Lock Haven, PA, hair follicle testing stands out compared to traditional urine testing due to its superior detection accuracy and reliability. Hair tests provide a longer detection window, typically capturing up to 90 days of drug use history. This longer window offers employers a comprehensive view into an individual’s substance use.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time.

It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
