Accredited Drug Testing offers extensive hair drug examinations in Markle, Indiana. If hair drug or alcohol testing is required, Accredited Drug Testing excels in hair analysis, with testing locations across the nation capable of administering these tests. Generally, 1.5 to 2 inches of hair from the crown or body is needed. Hair testing options include drugs, alcohol/ETG, or other tailored options.

Recently, hair follicle testing has become a more common method for substance screening. Employers, judicial systems, and addiction specialists often prefer hair testing over traditional urine tests. Hair follicle tests serve organizations with strict drug policies, judiciary requirements, and probation regulations. These tests present an extended detection span up to 90 days, involve supervised collection, and are highly cheat-proof. However, urine tests remain optimal for detecting recent drug use within 5 days.

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the strands of the growing hair. When collected near the scalp, it can reveal up to a roughly 3-month period of detection for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.

A section of 1.5 inches consisting of around 200 hairs (approximately the size of a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimum amount for screening and validation. For EtG, add-ons, and/or panels beyond 10, 150mg of the sample is advised. It's suggested to measure the sample using a jeweler’s scale. In cases where scalp hair is not accessible, an equivalent quantity of body hair may be gathered. 'Scalp hair' refers specifically to hair from the scalp. 'Body hair' encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key stages involved in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample into a lab's system. This process verifies that the sample was securely sealed and shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and concludes any missing data entry not supplied by an electronic chain of custody system.

Screening is an initial swift assessment for substances of abuse. Although Screening is a cost-efficient method to exclude drug usage for most samples, a positive screen should be confirmed for court admissibility. Samples with presumptive positive results in Screening necessitate ensuing confirmation.

In instances where a sample registers a presumptive positive in the Screening phase, an additional portion of hair is extracted from the original sample and readied for Extraction. During this step, drugs are isolated from hair at significantly lower concentrations than other methodologies (for example, urine or oral fluid), which is why hair drug testing presents the most challenging methodology to execute.

Confirmation of any positive screening outcome is performed with GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as required. The comprehensive lab process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation alongside the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair tests can identify drug use up to 90 days, unlike urine tests with a shorter detection timeframe.
  • Resistance to cheating: Cheating a hair drug test is extremely challenging, rendering the outcomes more reliable.
  • Chronological usage data: It offers a timeline of drug consumption over time, beyond just recent use.

Limitations:

  • Inability to capture recent use: Drugs typically become detectable in hair after around 5-7 days.
  • Expense: Hair drug tests are usually pricier than other methods of drug testing.
  • Outcome variability: Elements such as hair color and individual differences in hair growth can impact drug metabolite levels in hair.

Note: Commonly referred to as "hair follicle tests", the analysis targets the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Markle, IN, hair follicle testing triumphs over urine tests by demonstrating superior longevity in drug detection, with a window extending up to 90 days. This extensive detection period allows for a more comprehensive understanding of an individual's substance use history.

The consistent accuracy exhibited by hair follicle testing positions it as an optimal choice for employers seeking reliable substance use assessments. Organizations benefit from its precise analysis, translating into clearer, more informed decision-making than urine tests can provide. This enhanced reliability supports better compliance with workplace standards and reinforces safety measures.

Extended Detection Window

Hair follicle testing in Markle, IN, provides an expansive detection window, spanning up to 90 days, which significantly enhances the scope of evaluating substance use history.
