Hair Follicle Drug Testing - Kirkland, WA

What it is, How it works

Hair testing is increasingly valued as an effective means to detect drug and alcohol consumption. By embedding biomarkers within the fibers of hair strands as they grow, hair offers a comprehensive historical record of alcohol and drug use. When hair is taken near the scalp, it can offer a detection period of up to roughly 3 months for alcohol and drugs. The process of collecting hair is straightforward, challenging to tamper with, and easy to transport.

Collecting a 1.5-inch segment consisting of approximately 200 hair strands (about the width of a #2 pencil) from the scalp yields 100mg of hair, which is the optimal amount for screening and verification. For EtG, additional parameters, or assessments beyond 10 panels, 150mg of hair is recommended. It's advised to measure the specimen using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair may be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" pertains to all other hair types (facial, axillary, etc.).

Process Overview

There are four vital steps in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial handling of a sample within a laboratory system. This step includes ensuring the sample's proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.

Screening provides an initial rapid assessment for substance abuse. While it's an economical method to exclude drug use in most samples, a positive screening must be verified to be valid in legal proceedings. Samples that yield a presumptive positive in Screening necessitate secondary confirmation.

When Screening indicates a presumptive positive, additional hair is extracted from the original specimen and prepped for Extraction. In this stage, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most complex methodology to conduct.

Positive screening confirmations are performed using GC/MS, GC/MS/MS, or LC/MS/MS. Necessary presumptive positive samples are cleansed before confirmation. The entire laboratory workflow, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can indicate drug use for up to 90 days, in contrast to urine tests with a more limited detection timeframe.
• Improbability of deception: It proves exceedingly challenging to falsify a hair drug test, ensuring more precise results.
• Offers chronological data: It enables revealing a timeline of drug use over time, not just recent activity.

Limitations:

• Incapable of detecting recent use: Detectability of drugs in hair typically requires 5-7 days.
• Expense: Generally, hair drug tests incur higher costs than alternative drug testing methods.
• Result variability: Elements such as hair color and individual differences in hair growth can impact drug metabolite concentration in hair.

Note: Despite being labeled "hair follicle tests", the evaluation concerns the hair strand and excludes the follicle beneath the scalp.
