Hair Follicle Drug Testing - La Grande, WA

What it is, How it works

Hair analysis is now regarded as a robust method for detecting alcohol and drug use. The hair retains biomarkers within the fibers of the growing hair shaft, providing a historical record of alcohol and drug exposure. Collected near the scalp, it offers an approximately 3-month detection timeline for these substances. Hair collection is straightforward, resistant to tampering, and convenient for shipping.

A segment of 1.5 inches comprising around 200 hair strands (equivalent to the diameter of a #2 pencil) closest to the scalp produces 100mg, which is ideal for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen amount of 150mg is preferred. Utilizing a jeweler’s scale is advised for weighing the specimen. In cases where scalp hair is not an option, a similar quantity of body hair can be used. Head hair refers specifically to scalp hair, whereas body hair encompasses all other hair types (such as facial or underarm hair).

Process Overview

The four principal phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial assimilation of a sample into a lab’s system. This step confirms the sample is correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent in an electronic chain of custody system.

Screening carries out a rapid preliminary check for drug abuse. While it is an economical means to dismiss drug usage in most samples, confirmation is required for any positive screens to be admissible in legal proceedings. Samples testing positive in Screening necessitate a further confirmatory test.

For samples testing presumptive positive during Screening, additional hair from the initial sample is prepared for Extraction. Here, drugs are extracted from hair at concentrations lower than in other methods (e.g., urine or oral fluid), making hair drug testing a challenging technique.

Confirmation of any positive screen is done through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed when necessary before confirmation. From Accessioning to Confirmation, the entire lab process is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a 90-day span, unlike urine tests with shorter detection times.
• Hard to manipulate: Cheating a hair drug test is quite difficult, enhancing result reliability.
• Displays usage history: It reveals a drug use pattern over time, not just recent use.

Drawbacks:

• Incapable of detecting recent use: Drugs require about 5-7 days for detection in hair.
• Expense: Hair drug tests typically cost more than alternative testing methods.
• Result inconsistencies: Hair color and personal hair growth variations can influence drug metabolite concentrations in hair.

Note: Referred to as "hair follicle tests", the procedure actually examines the hair shaft and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in La Grande, WA, is suited for those seeking comprehensive drug use detection, far surpassing traditional urine tests.
