Hair Follicle Drug Testing - Crescent Lake, OR

What it is, How it works

Hair testing is now acknowledged as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug intake by embedding biomarkers in the fibers of the growing hair shaft. When gathered near the scalp, hair offers an approximately 3-month detection timeframe for alcohol and drugs. Hair is straightforward to collect, not easily tampered with, and convenient to ship.

Collecting a 1.5-inch piece of roughly 200 strands of hair (around the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the ideal amount for testing and verification. For EtG, additional tests, and/or assays beyond 10 panels, 150mg of the sample is advised. It is advisable to measure the sample on a jeweler’s scale. If scalp hair is not available, the equivalent amount of body hair can be used. When talking about head hair, it pertains solely to scalp hair. Body hair includes all other hair types (such as facial and axillary hair).

Process Overview

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

Accessioning covers the initial sample processing into a lab’s system. This involves checking that the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry that an electronic chain of custody system doesn’t provide.

Screening conducts an initial rapid check for drug misuse. Although Screening cost-effectively dismisses drug use in most samples, a positive screen needs validation to be accepted in court. Samples that test presumptively positive in Screening need subsequent confirmation.

If a sample tests presumptively positive in the Screening phase, more hair from the original sample is extracted for Extraction. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging technique to conduct.

Confirmation of any positive Screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples that test presumptively positive are washed before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, in contrast to urine tests which have a narrower detection period.
• Resistance to evasion: Cheating a hair drug test is very challenging, offering more accurate results.
• Provides usage history: It reveals a pattern of drug use over time, rather than only recent use.

Drawbacks:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug testing is generally costlier than other testing methods.
• Result variability: Factors such as hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

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

Why Hair Follicle Testing Beats Urine Testing

Hair follicle drug testing in Crescent Lake, OR, surpasses traditional urine tests in several ways. This method offers superior detection accuracy, capturing a wider range of substances over extended periods. Unlike urine tests, which may be affected by recent consumption and thus have a shorter detection window, hair testing provides comprehensive insights into an individual's drug use history. Employers value this for its consistency and reduced manipulation risk.

Extended Detection Window

In Crescent Lake, OR, the hair follicle drug test delivers an expanded detection window, revealing substance use over a 90-day span. This extensive period allows employers to thoroughly understand the drug use patterns of job candidates or employees. By exceeding the limited detection time of urine tests, hair follicle testing offers a robust tool for informed decision-making in hiring and workplace management.

Tamper-Resistant Testing Method

Hair follicle tests in Crescent Lake, OR, offer a tamper-resistant solution for drug screenings, minimizing the risk of adulteration. Unlike urine samples, hair strands provide stability and security, preventing efforts to alter or dilute test outcomes. This aspect guarantees that results are consistently accurate and defendable, making them a preferred choice for rigorous screening environments.
