Accredited Drug Testing offers comprehensive hair follicle drug testing services in Greenfield, Missouri. If you're in need of a hair-based drug or alcohol test, Accredited Drug Testing is your go-to expert, with testing centers available in every city across the nation that conduct these tests. You should ideally have 1.5 to 2 inches of hair available on your head's crown or body, as this can typically be used. Hair testing options include analysis for drugs, alcohol/ETG, or customized alternatives.

Hair follicle drug tests have become a common method for drug screening in recent years. Many employers, court systems, and substance abuse experts now prefer hair drug tests over traditional urine tests. Employers with zero-tolerance policies, courts, and those on probation often rely on hair follicle tests. These provide a longer detection window for drug use, typically up to 90 days, involve an observed collection process, and are almost impossible to tamper with. Nevertheless, for identifying drug use in the most recent 5 days, urine tests remain the most precise option.

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair encapsulates a comprehensive history of drug and alcohol use by locking biomarkers within the fiber of the growing strands. When procured near the scalp, it can reveal up to a 3-month detection period for alcohol and other substances. Hair sampling is straightforward, challenging to tamper with, and easy to dispatch.

A 1.5-inch segment containing roughly 200 hair strands (similar to the thickness of a #2 pencil) closest to the scalp yields 100mg, the optimal quantity for both screening and confirmation. For EtG and additional analyses or panels exceeding 10, a 150mg sample is advisable. Using a jeweler’s scale to weigh the sample is suggested. In the absence of scalp hair, an equivalent amount of body hair is acceptable. The term 'head hair' pertains exclusively to scalp hair. 'Body hair' encompasses all other hair varieties (such as facial or axillary hair).

Process Overview

The primary laboratory steps for processing a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of samples into the lab's system. It involves validating that the sample was adequately sealed and forwarded, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry not automated by an electronic chain of custody system.

Screening encompasses a swift preliminary analysis for illegal substances. Although Screening is a budget-friendly approach to exclude drug use for most samples, a detected positive needs confirmation to hold in legal proceedings. Any samples initially positive during Screening require additional confirmation.

With a presumptive positive in Screening, extra hair is extracted from the primary specimen for preparation in Extraction. At this phase, drug substances are derived from hair at considerably lower concentrations than other methods (like urine or oral fluid); hence hair drug screening stands as a particularly challenging technique.

Confirmation of any positive results is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS procedures. All samples preliminarily positive are cleansed as needed before confirmation. The entire laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug examinations can identify drug usage for up to 90 days, unlike urine tests with shorter detection spans.
  • Hard to falsify: Cheating on a hair drug test is extremely difficult, increasing result reliability.
  • Historical usage data: Offers a habitual drug use pattern over time, not solely recent usage.

Limitations:

  • Cannot detect immediate use: Drug detectability in hair begins approximately 5-7 days post-consumption.
  • Expense: Hair drug tests typically incur higher costs than other testing techniques.
  • Result variations: Elements such as hair color and growth variability can influence drug metabolite concentrations in the hair.

Note: Though commonly called "hair follicle tests," the analysis specifically targets the hair strand instead of the follicle beneath the scalp.
