Hair Follicle Drug Testing - Blackhawk, CA

What it is, How it works

Recognized as an effective method, hair testing offers valuable insights into drug and alcohol use. The fibers of the hair strand capture biomarkers, providing a comprehensive historical record of substance use. When taken near the scalp, hair samples can reveal a detection window that extends up to three months for drugs and alcohol. Collection is straightforward, tampering is challenging, and shipping is convenient.

A sample measuring 1.5 inches, comprising around 200 hair strands (similar in size to a #2 pencil) closest to the scalp, yields 100mg, which is optimal for analysis and validation. For tests including EtG, add-ons, and those exceeding 10 panels, 150mg is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, equivalent body hair can be collected. References to head hair pertain strictly to scalp hair, while body hair includes other types (facial, axillary, etc.).

Process Overview

Key steps in processing a drug test result at the laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial introduction of a sample into the laboratory’s workflow. This step ensures the sample was correctly sealed and transported, assigns it a random Laboratory Accessioning Number (LAN), and completes any extra data entry not included by an electronic chain of custody system.

Screening performs a rapid preliminary test for drugs of abuse. While this is a cost-effective way to exclude drug usage in most samples, a positive result requires confirmation to be legally valid. Any samples with a presumptive positive result from Screening need secondary confirmation.

If there is a presumptive positive at the Screening phase, additional hair is extracted from the original sample for the Extraction phase. Here, drug traces are isolated from hair at much lower concentrations than other methods like urine or oral fluid, making hair drug screening especially challenging.

Positive results from Screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples that are presumptively positive are washed before confirmation, if required. The entire process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to 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 offer a shorter detection timeframe.
• Hard to falsify: Tampering with a hair drug test is notably difficult, enhancing the credibility of results.
• Reports usage history: It details a pattern of drug consumption over time, unlike tests that only reflect recent use.

Limitations:

• Does not show recent drug intake: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to be pricier than other testing approaches.
• Result variability: Variables like hair color and individual growth rates can influence the concentration of drug residues.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle below the scalp.
