Hair Follicle Drug Testing - Covington, WA

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. It captures a comprehensive history of these substances by embedding biomarkers in the fibers of the hair as it grows. When taken near the scalp, hair can provide a detection window of up to three months for alcohol and drugs. The collection of hair is straightforward, resistant to tampering, and can be easily transported.

A 1.5-inch hair sample from about 200 strands (roughly the size of a #2 pencil) near the scalp will yield 100mg of hair, which is the ideal amount for analysis and validation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to assess the specimen using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair is acceptable. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for a drug test outcome encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial phase of transferring a sample into the laboratory's system. This involves ensuring the sample was sealed and shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and completing any extra data not already provided by an electronic chain of custody protocol.

Screening entails a preliminary inspection for illicit substances. This cost-effective approach helps eliminate drug use in most samples, though a positive result must be confirmed for legal acceptability. Samples that are presumptively positive in the Screening phase necessitate further confirmation.

In the event of a presumptive positive during Screening, additional hair is taken from the original sample for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (such as urine or oral fluids), making hair drug screening a particularly challenging technique.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed for confirming any positive Screening results. Presumptive positive specimens are cleansed prior to their confirmation when necessary. The complete laboratory process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with a shorter detection span.
• Resistance to tampering: The difficulty in altering a hair drug test enhances result accuracy.
• Chronological usage data: It can chart a pattern of drug use over an extended timeframe, rather than just recent usage.

Limitations:

• Lack of detection for recent use: Drugs typically become detectable in hair after approximately 5-7 days.
• Higher expense: Generally, hair drug tests cost more than other testing options.
• Result variability: Variations in results can occur due to differing hair colors and individual growth rates influencing drug metabolite concentration in hair.

Note: Though frequently termed "hair follicle tests", the assessment actually examines the hair strand, not the follicle beneath the scalp.
