Hair Follicle Drug Testing - Clayton, WA

What it is, How it works

Hair testing has increasingly been recognized as an effective method for identifying drug and alcohol consumption. Hair captures a chronicle of alcohol and drug use by embedding biomarkers within the fibers as the hair strand grows. When taken from near the scalp, hair samples can reveal drug and alcohol use within a roughly 3-month timeframe. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) from the scalp is needed to obtain 100mg of hair, which is the optimal amount for both screening and verification. For EtG, supplementary tests, and/or screenings exceeding 10 panels, a sample of 150mg is ideal. It's advisable to measure the hair sample with a jeweler's scale. If scalp hair isn’t available, a comparable quantity of body hair is permissible. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (like facial and axillary hair).

Process Overview

The laboratory procedure for processing a drug test involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the laboratory’s system. This stage ensures the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and inputs any additional data not included by an electronic chain of custody system.

Screening includes a preliminary assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug consumption in most cases, any positive screen must be confirmed for it to be legally accepted. Samples that appear positive in the Screening phase require further confirmation.

If Screening results are positive, additional hair is used from the original sample for Extraction. At this phase, drugs are isolated from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the more challenging methodologies.

Confirmation of a positive Screening result takes place using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are assumed positive are cleaned prior to confirmation if necessary. The complete laboratory operation from Accessioning to Confirmation is reviewed in accordance with both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug usage for up to 90 days, contrasting with urine tests which cover a shorter duration.
• Difficulty to cheat: Manipulating a hair drug test is notably challenging, resulting in more reliable outcomes.
• Provides historical data: Offers a sequence of drug use over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: It generally takes 5-7 days for drugs to be traceable in hair.
• Cost: Hair drug tests typically incur higher costs than other types of drug tests.
• Variations in results: Aspects such as hair color and individual differences in hair growth can influence drug metabolite levels in hair.

Note: Despite often being termed "hair follicle tests", the procedure actually assesses the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Clayton, WA, hair follicle testing surpasses urine testing due to several distinct advantages. A prominent benefit is the superior accuracy in detecting drug use, thanks to an extended detection window of up to 90 days.
