Hair Follicle Drug Testing - Sherwood, OR

What it is, How it works

Hair testing is now recognized as a formidable method for identifying drug and alcohol consumption. The hair captures a prolonged account of alcohol and other drugs by embedding biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can reveal up to an approximate 3-month window for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch segment of around 200 hair strands (roughly the thickness of a #2 pencil) from the scalp will yield 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, it is advised to collect 150mg. Using a jeweler’s scale to measure the sample is suggested. If scalp hair isn’t available, an equivalent quantity of body hair is sufficient. When mentioning head hair, we mean solely scalp hair. Body hair pertains to all other varieties (facial, axillary, etc.).

Process Overview

The primary steps in lab processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial process of entering a sample into a lab’s system. This step involves ensuring the sample was adequately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry overlooked by an electronic chain of custody system.

Screening presents an initial examination for the presence of abused drugs. Screening is a budget-friendly approach to exclude drug usage on the most samples; however, a positive outcome necessitates confirmation for court validity. Samples with a presumptive positive result in Screening need a subsequent confirmation.

Should a sample show a presumptive positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. During this step, drugs are isolated from hair at significantly lower levels compared to other methods (ex. urine or oral fluid), marking hair drug testing as one of the most intricate methodologies to execute.

Confirmation for any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if required. From Accessioning to Confirmation, the complete laboratory process is subjected to review under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage up to 90 days, as opposed to urine tests which have a much shorter detection timeframe.
• Challenging to tamper with: Hair drug tests are very difficult to manipulate, ensuring higher accuracy.
• Supplies historical insight: It provides a usage pattern over time, not just immediate use.

Limitations:

• Incapable of detecting recent usage: Drugs become identifiable in hair approximately after 5-7 days.
• Expense: Hair drug tests typically cost more compared to other testing methods.
• Result fluctuations: Factors such as hair color and individual differences in hair growth might alter drug metabolite concentration in the hair.

Note: While often called "hair follicle tests", the test actually analyzes the hair strand and not the follicle beneath the scalp.
