Hair Follicle Drug Testing - Lookingglass, OR

What it is, How it works

Hair analysis is increasingly recognized as an effective method for detecting substance use. Hair offers a comprehensive record of alcohol and drug consumption by capturing biomarkers within the strand’s fibers. When taken near the scalp, hair samples can reveal usage over a period of up to three months. The collection process is straightforward, tampering is challenging, and the samples are easy to transport.

A hair sample measuring 1.5 inches and comprising roughly 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for evaluation and verification. For EtG, additional tests, or panels exceeding ten, a 150mg specimen is advisable. Using a jeweler’s scale to measure the specimen is suggested. Should scalp hair be inaccessible, equivalent body hair may be used. References to head hair pertain solely to scalp hair. All other types such as facial and axillary hair are classified as body hair.

Process Outline

The laboratory analysis of a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where samples are entered into the lab’s system. This step involves confirming the sample's proper seal and shipment, assigning a Laboratory Accessioning Number (LAN), and completing any missing data entries not covered by an electronic chain of custody.

Screening serves as an initial, economical assessment for identifying drug use. Though effective for most samples, a positive initial result must be validated to stand in court. Samples with an indicative positive in this phase require further confirmation testing.

For samples indicating a potential positive in Screening, additional hair is extracted from the initial sample for further processing. In the Extraction phase, substances are obtained from hair in much lower concentrations compared to other analysis methods (e.g., urine or oral fluid), making hair analysis particularly complex.

Any affirmative result from Screening undergoes Confirmation using methods like GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples are cleaned before confirmation, if necessary. The entire process, from Accessioning through Confirmation, adheres to CAP (College of American Pathologists) guidelines for Hair and ISO/IEC 17025 standards.

Pros of hair analysis for drugs:

• Extended detection period: Hair tests identify drug use for as long as 90 days, surpassing the shorter detection period of urine tests.
• High resistance to tampering: Cheating a hair test is quite challenging, ensuring more reliable outcomes.
• Chronological data: The test records a timeline of substance use, offering insights into patterns rather than just recent activity.

Challenges:

• Inability to detect recent consumption: Drugs become identifiable in hair after approximately 5-7 days.
• Expense: Hair analysis is often more costly than alternative testing types.
• Result variability: Factors like hair color and individualized growth rates can influence drug metabolite levels in the hair.

Note: Although often termed as "hair follicle tests", the procedure examines the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why is hair follicle testing preferred over traditional urine tests in Lookingglass, OR? The answer lies in superior detection accuracy and reliability. Hair tests offer enhanced sensitivity, capturing a longer history of drug usage. Unlike urine tests, which cover a short detection window, hair tests provide a comprehensive view, making them the better choice for ensuring a drug-free environment.

Extended Detection Window

Hair follicle testing excels with its extended detection window, particularly in Lookingglass, OR, where up to 90 days of substance history can be reviewed. This advantage offers employers a detailed insight into an employee or candidate's drug use over a longer term, differing from the limited detection capability of urine tests. Such comprehensive information aids in robust decision-making processes.

Tamper-Resistant Testing Method

In Lookingglass, OR, tamper-resistant hair follicle testing provides a robust solution to prevent sample adulteration. The intrinsic nature of hair testing ensures that the results are reliable and accurate, minimizing the chances of manipulation. This inherent resistance to tampering makes hair follicle tests a preferred choice for those seeking trustworthy outcomes in drug testing.
