Hair Follicle Drug Testing - Brownlee, OR

What it is, How it works

Recognized as an effective method, hair testing has emerged as a vital means for identifying drug and alcohol consumption. Hair retains a substantial historical record of drug and alcohol exposure by encapsulating biomarkers within the strands of hair as they grow. When sourced near the scalp, hair offers a detection window extending up to approximately three months for alcohol and other substances. It’s straightforward to collect, relatively resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (akin to a #2 pencil's thickness) close to the scalp, yields 100mg, ideal for preliminary screening and confirmation. For EtG, additional tests, and/or assessments exceeding ten panels, a specimen weighing 150mg is advisable. It's recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, an equivalent portion of body hair is acceptable. References to head hair specifically denote scalp hair, whereas body hair refers to all other types such as facial and axillary hair.

Process Overview

The laboratory processing of a drug test result generally unfolds in four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial intake of a sample into a laboratory's processes. It involves ensuring the sample's seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not included in an electronic chain of custody system.

Screening serves as an initial assessment for substances of abuse. Although Screening provides a cost-efficient method to discard many negative samples, any positive identification must undergo Confirmation for legal acceptance. Thus, samples initially testing positive in Screening require a follow-up confirmation process.

Presumptively positive samples at the Screening stage are advanced by extracting more hair from the original specimen for the Extraction process. During Extraction, drugs are retrieved from hair at significantly lower concentrations than alternative methods (such as urine or oral fluid), signifying the complexities of hair drug screening.

To affirm any positive screening findings, methods like GC/MS, GC/MS/MS, or LC/MS/MS are utilized in the Confirmation phase. As required, all presumptive positive samples undergo washing before confirmation. The comprehensive laboratory procedure from Accessioning to Confirmation is subject to scrutiny under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can identify drug use up to 90 days back, surpassing the shorter detection capabilities of urine tests.
• Testing integrity: The reliability of results is heightened due to the difficulty of manipulating a hair drug test.
• Comprehensive data: Capable of outlining a consistent drug use pattern over time, rather than isolated incidents.

Limitations:

• Recent use detection: Drugs become detectable in hair approximately 5-7 days post-usage.
• Expense: Comparably, hair drug tests entail higher costs than other drug testing options.
• Result variability: Factors such as hair color and personal variations in hair growth can influence drug metabolite concentrations in hair samples.

Note: Although often termed "hair follicle tests", the actual analysis is executed on the hair strand, not the follicle beneath the scalp.
