Hair Follicle Drug Testing - Novelty, WA

What it is, How it works

Recognized as an effective means for detecting substance use, hair tests offer a long-term record of drug and alcohol intake by capturing biomarkers within the hair fibers as they grow. When hair is cut close to the scalp, it offers a detection span of roughly three months for substances. Hair is straightforward to gather, resistant to alteration, and convenient to send.

Collecting a 1.5-inch sample, consisting of approximately 200 hair strands (about the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for screening and confirming. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg specimen is advised. Using a jeweler's scale to measure the specimen's weight is recommended. Should scalp hair be inaccessible, a similar volume of body hair can be taken. Head hair refers only to scalp hair, whereas body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The laboratory processing of drug testing results encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's initial entry into the laboratory system, ensuring proper sealing and shipping, assigning a randomized LAN (Laboratory Accessioning Number), and completing any missing data not supplied by an electronic chain of custody system.

Screening is a preliminary rapid check for substance abuse. While it is a budget-friendly method to dismiss drug use in the majority of samples, a positive screening requires confirmation to be accepted in legal settings. Samples that test presumptively positive in Screening must undergo subsequent confirmation.

If indicated as presumptively positive during Screening, additional hair is drawn from the original sample and processed for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging technique.

Confirmation of any initial positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptive positives undergo washing before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair categorization and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can detect substance use for as long as 90 days, unlike urine tests which have a shorter scope.
• Difficult to manipulate: It is notably hard to manipulate a hair drug test, enhancing result precision.
• Provides historical insights: Offers a timeline of substance use across a duration, rather than merely recent use.

Limitations:

• Inability to reflect recent usage: Drugs become traceable in hair after approximately 5-7 days.
• Expense: Hair drug tests usually cost more than alternate testing methods.
• Result variability: Elements like hair coloration and individual differences in hair growth can influence drug metabolite levels in the hair.

Note: Although often labeled as "hair follicle tests," the actual examination is performed on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The benefits of hair follicle testing in Novelty, WA over traditional urine tests are numerous. Hair testing offers superior detection accuracy, capturing a broader range of substances over an extended timeframe.
