Hair Follicle Drug Testing - West Colusa, CA

What it is, How it works

Hair analysis has emerged as a formidable method for detecting substance use, including alcohol. Hair captures a historical record of alcohol and drugs by embedding biomarkers within the fiber of the expanding hair shaft. When collected near the scalp, hair offers up to an approximately three-month window of detection for alcohol and other substances. It is straightforward to collect, relatively challenging to tamper with, and convenient for shipping.

A 1.5-inch segment of roughly 200 hair strands (comparable to the girth of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, a specimen of 150mg is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. If scalp hair isn't available, a comparable quantity of body hair can be obtained. By head hair, we specifically mean scalp hair. Body hair encompasses all other types such as facial or axillary hair.

Process Overview

The comprehensive steps in laboratory processing for drug test results involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the introduction of the sample into a laboratory's system. This step includes confirming that the sample was correctly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and executing any required additional data entry that isn't covered by an electronic chain of custody system.

Screening involves a preliminary rapid test for drug abuse. While it is a cost-effective approach to exclude drug use in the majority of samples, a positive result from screening necessitates confirmation to be legally valid. Any sample that tests presumptively positive during Screening requires subsequent confirmation.

If a sample is presumed positive during the Screening phase, an additional portion of hair is taken from the initial specimen and prepared for Extraction. During Extraction, drugs are drawn from hair at significantly lower levels compared to other methods (such as urine or oral fluid), highlighting why hair drug testing is the most challenging method to execute.

Confirmation of any positive results from screening is performed using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if needed. The full laboratory procedure from Accessioning to Confirmation is subject to review under the CAP (College of American Pathologists) Hair classification and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a briefer detection period.
• Difficulty to defraud: It is notably hard to deceive a hair drug test, which enhances the accuracy of its results.
• Supplies historical data: It can indicate a pattern of substance use over time rather than just recent consumption.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing methods.
• Variability in outcomes: Elements like hair color and individual hair growth variations can impact the concentration of drug metabolites in hair.

Note: The test is often labeled as a "hair follicle test", but it actually analyzes the hair strand instead of the follicle beneath the scalp.
