Hair Follicle Drug Testing - Crane, OR

What it is, How it works

Hair assessment has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of substance use by embedding biomarkers in the strands of the growing hair. When taken close to the scalp, hair can reveal up to around a 90-day window of detection for alcohol and substances. The collection process is straightforward, relatively tamper-proof, and easy to transport.

A 1.5-inch hair sample of approximately 200 strands near the scalp provides 100mg of hair, the preferred sample size for analysis and verification. For EtG, additional tests, or when exceeding 10 panels, a 150mg specimen is advisable. Using a jeweler’s scale is suggested for weighing the sample. If there is no scalp hair, an equivalent quantity of body hair can be used. References to head hair specifically mean scalp hair. Body hair covers all other types (facial, axillary, etc.).

Process Overview

The laboratory process for processing a hair drug test comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves introducing a sample into the lab's system initially. This step includes checking if the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry needed outside of an electronic chain of custody system.

Screening is a preliminary review for substances of abuse. While Screening is a budget-friendly method to dismiss drug use for most samples, a positive screen must be verified to stand in a legal setting. Samples with presumptive positives in Screening go through a secondary confirmation.

If a sample is presumptively positive during Screening, additional hair is taken from the initial sample and prepared for Extraction. In this phase, substances are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to carry out.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Challenging to manipulate: Altering hair drug test outcomes is very difficult, enhancing result reliability.
• Reveals usage trends: It can illustrate a pattern of drug consumption over time, not just recent use.

Limitations:

• Unable to identify recent consumption: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are often pricier than other methods.
• Result variability: Elements like hair color and individual growth rates affect drug metabolite concentration in hair.

Note: Though commonly called "hair follicle tests," the procedure examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Crane, OR, hair follicle testing surpasses urine testing in several ways. One of the main advantages is its extended detection window, allowing for a more thorough analysis of drug use.
