Hair Follicle Drug Testing - Prairie Ridge, WA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol use. Hair offers an extended timeline of substance exposure by encapsulating biomarkers within the fibers as hair grows. When cut near the scalp, hair samples can reveal up to about three months of alcohol and drug usage history. Hair is straightforward to collect, challenging to alter, and convenient to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (about the width of a #2 pencil) near the scalp will yield 100mg, the ideal amount for both screening and confirmation tests. When conducting tests like EtG, add-ons, or those beyond 10 panels, 150mg of hair is suggested. Measuring the sample with a jeweler's scale is recommended. If scalp hair isn't available, an equivalent amount of body hair can be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other types (such as facial, axillary, etc.).

Process Overview

There are four primary stages in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial incorporation of a sample into a laboratory's system. This process includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not recorded by an electronic chain of custody system.

Screening acts as a preliminary test to quickly determine the presence of substance abuse. While Screening is cost-efficient for excluding drug use in most cases, a positive result needs confirmation for legal admissibility. Samples that presumptively test positive in Screening require additional confirmation.

Should a sample indicate a presumptive positive in Screening, further hair is extracted from the initial sample for the Extraction process. Here, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging procedure to execute.

Confirmation of any positive Screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples that are presumptively positive undergo washing before Confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection: Hair drug tests can identify drug use up to 90 days, unlike urine tests, which have a shorter detection period.
• High accuracy: It's notably hard to manipulate a hair drug test, leading to more reliable results.
• Historical insight: Provides a record of drug consumption over time, not just recent usage.

Limitations:

• Unable to identify recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Result variability: Variables such as hair color and individual hair growth rates can impact the drug metabolite concentration in hair.

Note: Despite commonly being called "hair follicle tests," the examination is performed on the hair strand, not the follicle beneath the scalp.
