Hair Follicle Drug Testing - Naselle, WA

What it is, How it works

Regarded as a robust means for identifying drug and alcohol consumption, hair testing captures long-term alcohol and drug histories by encapsulating biomarkers within the growing hair's fibers. When samples are taken near the scalp, hair offers roughly a three-month detection period for alcohol and other drugs. Hair samples are easy to collect, somewhat difficult to tamper with, and convenient for shipping.

A 1.5-inch segment consisting of about 200 hair strands (approximately the diameter of a #2 pencil) from near the scalp yields 100mg of hair, which is the preferred quantity for screenings and confirmations. For EtG and additional 10-panel tests, 150mg is advised. It is recommended to weigh the sample using a jeweler’s scale. In cases where scalp hair is not accessible, a similar portion of body hair can be gathered. References to head hair specifically mean scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

In laboratory processing of drug test results, the key stages are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system. This step involves checking that the sample was securely sealed and shipped, assigning a random Laboratory Accessioning Number (LAN), and completing any necessary data entry not handled by an electronic chain of custody system.

Screening serves as a preliminary inspection for substance abuse. Although Screening is an economical option to dismiss drug use in most samples, positive results require confirmation to be valid legally. Samples that test presumptively positive in Screening demand additional confirmation.

If a sample signals positive at the Screening phase, more hair is extracted from the original sample and set up for Extraction. During Extraction, substances are removed from hair at significantly lower concentrations than in other approaches (e.g., urine or oral fluid), making hair analysis one of the most complex methodologies.

Validated positive Screening findings undergo confirmation assays like GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptively positive are cleansed before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is performed under the scrutiny of both the CAP (College of American Pathologists) Hair initiative and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analysis can identify drug usage up to 90 days prior, whereas urine tests provide a shorter detection span.
• Hard to falsify: Hair drug assessments are very challenging to dupe, resulting in more reliable results.
• Historical data provision: It delivers a pattern of drug usage over a duration, not merely recent consumption.

Limitations:

• Cannot identify recent usage: Drugs need about 5-7 days to become noticeable in hair.
• Expense: Hair drug evaluations are generally costlier than other testing practices.
• Outcome variability: Elements like hair color and personal differences in hair growth might influence the presence of drug metabolites in hair.

Note: Although often termed as "hair follicle tests", the examination targets the hair strand, excluding the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

When considering drug testing in Naselle, WA, hair follicle testing stands out against traditional urine analyses. One significant advantage is its capacity to detect drugs over a longer timeline, typically up to 90 days, offering enhanced accuracy and reliability compared to the short-term detection of urine tests.
