Hair Follicle Drug Testing - Evans, WA

What it is, How it works

Hair testing is recognized as an effective method for identifying substance use. Hair offers an extended timeline of alcohol and drug use by capturing biomarkers within the developing hair strand fibers. When obtained near the scalp, hair can reveal a detection period of up to nearly three months for alcohol and drugs. Hair collection is straightforward, moderately challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the preferred quantity for screening and verification. For EtG testing and/or panels exceeding 10, 150mg of the hair sample is advised. It's suggested to use a jeweler’s scale for weighing the sample. If scalp hair isn't available, equivalently, body hair can be collected. Head hair refers specifically to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four primary phases in the lab processing for a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a laboratory’s framework. This process verifies that the sample is correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data that isn't covered by an electronic chain of custody system.

Screening provides a preliminary assessment for drugs of abuse. Although Screening is a cost-effective strategy to rule out drug use in most samples, a positive result in screening requires confirmation to be considered valid in legal settings. Samples with positive screening outcomes necessitate secondary confirmation.

If a sample emerges as positive during Screening, additional hair is retrieved from the initial specimen for the Extraction phase. Here, drugs are extracted from hair at concentrations much lower than other methodologies (such as urine or oral fluid), explaining why hair drug screening is a complex procedure to execute.

Confirmation of any positive screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if needed. The comprehensive laboratory procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended observation period: Hair drug tests can trace drug use for up to 90 days, in contrast with urine tests which feature a more limited detection scope.
• Hard to alter: It is highly challenging to deceive a hair drug test, thus enhancing result accuracy.
• Offers longitudinal data: It allows for observing drug use patterns over time rather than just recent intake.

Limitations:

• Cannot identify recent intake: Detection of drugs in hair takes around 5-7 days.
• Expense: Hair drug tests tend to be pricier compared to other drug testing techniques.
• Result variations: Elements like hair color and individual hair growth differences can impact drug metabolite concentrations in the hair.

Note: Although frequently called "hair follicle tests", the examination analyzes the hair strand rather than the follicle beneath the scalp.
