For those searching for complete hair follicle drug screening in Dellwood, Missouri, Accredited Drug Testing is the go-to provider. If there's a need for hair drug or alcohol testing, our focus on hair testing comes with facilities across all cities nationwide ready to conduct a comprehensive hair assessment. Typically, a length of 1.5 to 2 inches of hair is required, either from the scalp or body. Hair analysis encompasses drugs, alcohol/ETG, or tailored testing options.

Hair follicle drug tests have become increasingly prevalent. Many organizations, judicial entities, and Substance Abuse professionals are replacing urine tests with hair drug screenings. They serve employers with strict no-drug policies, courts, and individuals on probation. The main advantage of these tests is a longer detection period, often up to 90 days, obtained through a monitored collection, minimizing chances of manipulation. Nonetheless, for identifying recent drug use within five days, urine tests remain superior.

What it is, How it works

The examination of hair has increasingly been recognized as an effective method for detecting drug and alcohol consumption. Hair signifies an extended history of drug and alcohol intake by embedding biomarkers within the strands as they grow. When taken near the scalp, a hair sample can indicate substance use over up to a three-month period. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.

A key sample consists of a 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil’s diameter) closest to the scalp, yielding 100mg of hair, which is optimal for screening and verification. For tests like EtG, additional screens, or those exceeding 10 panels, a 150mg specimen is advised. It’s best to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, a comparable amount of body hair can be collected. By head hair, we mean only scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The main phases in processing drug test results in a lab consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the sample's entry into the lab processing system. This phase ensures the sample was properly sealed and delivered, assigns it a unique LAN (Laboratory Accessioning Number), and completes necessary data entry absent in an electronic chain of custody system.

Screening provides an initial, rapid assessment for drugs of abuse. While Screening is economically efficient for excluding drug use in most samples, a positive result must be confirmed to be legally valid. Any samples showing a presumptive positive in Screening require an additional confirmation step.

Should a sample show a presumptive positive during Screening, further hair is taken from the initial batch and processed for Extraction. This phase isolates drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), underlining the complexity of hair drug testing.

The Confirmation of positive screening findings is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing before confirmation as required. Each stage from Accessioning through to Confirmation is reviewed according to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

  • Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests with a shorter detection timeframe.
  • Hard to deceive: Hair drug testing is challenging to circumvent, yielding more reliable results.
  • Illustrates past usage: This test can show a history of drug use, rather than just recent consumption.

Drawbacks:

  • Inability to detect recent use: Drug traces appear in hair only after approximately 5-7 days.
  • Expense: Compared to other drug testing techniques, hair drug tests generally incur higher costs.
  • Result variability: Factors like hair color and personal variations in hair growth may influence drug metabolite concentrations in the hair.

Note: Commonly called "hair follicle tests", this method examines the hair strand rather than the follicle beneath the scalp.
