Hair Follicle Drug Testing - Tumwater, WA

What it is, How it works

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug exposure by capturing biomarkers within the hair strand as it grows. By taking a sample near the scalp, a hair test can reveal drug and alcohol usage for up to a 3-month period. Collecting hair is not only straightforward but also hard to tamper with and easy to transport.

A hair sample of 1.5 inches, consisting of roughly 200 strands (similar to a #2 pencil thickness), taken nearest to the scalp, will yield about 100mg, which is optimal for both screening and verification. For EtG, additional tests, and/or over 10-panel tests, 150mg is advised. It's best to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be gathered. When specifying head hair, the reference is strictly to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The core stages in laboratory processing of a drug test output encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the initial phase of integrating a specimen into a laboratory’s system. This encompasses ensuring the sample has been correctly sealed and sent, generating a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.

Screening serves as a preliminary rapid assessment for substance abuse. Although Screening is an economical method for excluding drug use in most samples, a positive result must be confirmed for it to be valid in legal proceedings. Any samples that yield a presumptive positive during Screening necessitate additional confirmation.

If Screening suggests a sample is positive, more hair is extracted from the initial sample for the Extraction stage. Here, drugs are removed from hair at much lower concentrations compared to other methods (like urine or oral fluid testing), making hair drug testing a more challenging methodology.

Confirming any presumptive positive from Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under CAP (College of American Pathologists) Hair designation and certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, while urine tests have a shorter detection duration.
• Hard to manipulate: Achieving deception in a hair drug test is challenging, leading to more reliable results.
• Historical insight: It provides a timeline of drug use habits over an extended period, versus just recent activity.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Generally, hair drug tests are pricier compared to other drug detection methods.
• Result variances: Elements like hair color and personal hair growth differences can influence drug metabolite levels in the hair.

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