Hair Follicle Drug Testing - Dempsey, OK

What it is, How it works

Using hair analysis has become recognized as a potent method for detecting drug and alcohol consumption. Hair offers a longitudinal record of alcohol and drug intake by capturing biomarkers within the structure of the hair strand as it grows. When collected near the scalp, hair can reveal a detection window of approximately three months for various substances. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches with around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal amount for both screening and verification. For EtG tests, additions, and/or panels exceeding 10, a sample of 150mg is suggested. We advise measuring the sample on a jeweler's scale. If scalp hair is unavailable, a similar quantity of body hair may be substituted. When indicating head hair, we mean scalp hair exclusively. Body hair pertains to all other varieties (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary processing of a sample into a laboratory’s database. This procedure includes confirming that the sample's seal and shipment were intact, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not provided by a digital chain of custody system.

Screening entails a preliminary swift evaluation for potential drug abuse. While a cost-effective means of ruling out drug use in most cases, any positive screen findings must undergo confirmation to be considered valid in legal contexts. Samples testing presumptively positive in Screening require further verification.

Should a sample test presumptively positive in the Screening phase, additional hair will be extracted from the initial sample and prepped for Extraction. During this process, drugs are isolated from hair at considerably lower concentrations than other methodologies (e.g., urine or oral fluids), rendering hair drug testing as the most challenging methodology to execute.

Any positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to Confirmation, all presumptively positive samples are cleansed as necessary. The comprehensive laboratory workflow from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, compared to the shorter span for urine tests.
• Difficult to manipulate: Cheating on a hair drug test is significantly challenging, enhancing result accuracy.
• Historical usage insight: It delivers a timeline of drug consumption across an extended timeframe, not simply recent use.

Limitations:

• Incapacity to detect recent usage: Approximately 5-7 days are required before drugs become traceable in hair.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Factors like hair color and personal hair growth variations may influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the test inspects the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Choosing hair follicle testing over traditional urine tests in Dempsey, OK, gives a clear advantage. Hair tests offer a longer detection window, uncovering drug use over the past 90 days, whereas urine tests cover a shorter span.
