Hair Follicle Drug Testing - Kenmore, WA

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol exposure by encasing biomarkers within the matrix of the hair as it grows. Proximal hair samples, taken from near the scalp, can retrospectively analyze drug and alcohol use over a span of up to three months. Hair collection is straightforward, challenging to tamper with, and simplifies logistics for shipping.

Collecting a 1.5-inch sample comprising roughly 200 strands next to the scalp equates to about 100mg of hair, which is the ideal sample size for screening and confirmatory tests. For tests such as EtG, additional panels, or those exceeding 10 panel tests, a 150mg sample is preferable. It is advised to weigh the specimen using a jeweler's scale. If scalp hair isn't obtainable, an equivalent mass of body hair can be used. Reference to head hair pertains solely to scalp hair, while body hair encompasses all other kinds (e.g., facial, axillary).

Process Overview

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

During Accessioning, the sample is initially entered into the laboratory system. This step ensures that the sample was correctly sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and completes necessary data entry not covered by an electronic chain of custody.

Screening acts as a preliminary assessment to identify substances of abuse. Although it is an economical approach to exclude drug consumption in numerous samples, only confirmed positive results hold legal credibility. Presumptively positive samples necessitate secondary validation.

Presumptive positive results from Screening lead to further hair extraction from the initial specimen for the Extraction stage. Drugs are isolated from the hair at concentrations much lower than those in alternative testing methods (e.g., urine, oral fluid), which underscores the complexity of hair drug screening.

Confirmation of any presumptive positive findings is executed through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating a preliminary positive are cleansed prior to confirmation if deemed necessary. The entire Accessioning through Confirmation procedure adheres to regulatory reviews, specifically by the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays can determine drug use over a 90-day duration, surpassing the shorter detection scope of urine tests.
• Resistance to tampering: The likelihood of deceit in hair drug assessments is minimal, thus ensuring accuracy in results.
• Historical insight: It provides a chronological account of drug use, distinguishing between persistent and recent consumption.

Limitations:

• Inability to detect immediate use: Drugs generally become evident in hair only after 5-7 days.
• Expense: Hair drug tests usually incur higher costs compared to other testing techniques.
• Result variability: Diversities in hair color and personal hair growth rates can influence drug metabolite levels within the hair matrix.

Note: Commonly referred to as "hair follicle tests," the procedure actually examines the hair shaft, not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Kenmore, WA, hair follicle testing stands out as a highly effective alternative to traditional urine tests. Its superior detection capabilities provide a more complete picture of an individual's drug use history.
