Hair Follicle Drug Testing - Darrington, WA

What it is, How it works

Hair analysis has emerged as a significant instrument for identifying drug and alcohol consumption. Hair retains a comprehensive timeline of alcohol and drugs by embedding biomarkers within the fibers of the hair strand as it grows. When gathered close to the scalp, it can reveal substance use for a period of up to nearly 3 months. Hair is straightforward to collect, challenging to tamper with, and simple to transport.

A strand sample of 1.5 inches consisting of roughly 200 hairs (comparable to the width of a #2 pencil) from near the scalp will yield 100mg of hair, which is the optimal quantity for analysis and confirmation. For EtG, additional elements, and/or examinations exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. References to head hair pertain exclusively to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the initial integration of a sample into the laboratory’s system, ensuring it’s been secured and transported appropriately, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain of custody system.

Screening conducts a preliminary evaluation for the presence of drugs. While it is a cost-efficient method to exclude drug presence in most specimens, a positive Screening result requires additional confirmation to be viable in legal environments. Any samples testing presumptively positive during Screening necessitate further verification.

Upon a presumptive positive result in Screening, an additional hair sample is extracted from the initial specimen and prepared for Extraction. In this stage, substances are isolated from hair at a notably lower concentration than in other procedures (such as urine or oral fluid), which contributes to hair drug screening being the most intricate methodology to execute.

Any positive screening result is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens are cleaned prior to the confirmation as needed. The comprehensive laboratory process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug testing can identify drug usage for up to 90 days, as opposed to the shorter detection period for urine tests.
• Hard to manipulate: Manipulating hair drug tests is exceedingly difficult, which enhances result accuracy.
• Offers historical insights: It can present a drug use pattern over time, not just recent consumption.

Limitations:

• Cannot identify recent consumption: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be costlier compared to other testing methods.
• Result variability: Influences such as hair color and personal differences in hair growth can impact drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests", the procedure actually examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Darrington, WA

Hair testing stands out against traditional urine testing by offering superior detection accuracy and reliability.
