Hair Follicle Drug Testing - Oxnard, CA

What it is, How it works

The utilization of hair testing has emerged as an influential method for identifying alcohol and drug consumption. Hair can capture a long-term record of drug and alcohol use by encapsulating biomarkers within the strands of hair as it grows. When taken from near the scalp, hair testing can offer an approximate 3-month window for detecting substances like alcohol and various drugs. The process of collecting hair samples is straightforward, it’s somewhat resistant to tampering, and shipping is uncomplicated.

A sample of hair measuring 1.5 inches and consisting of roughly 200 strands (similar in diameter to a #2 pencil) closest to the scalp will yield approximately 100mg, which is the optimal quantity for both screening and confirmation. For tests like EtG, and those exceeding 10 panels, a 150mg sample is advisable. It's recommended to weigh the sample on a jeweler’s scale. For cases where scalp hair is unavailable, a similar volume of body hair can be utilized. Mention of head hair specifically pertains to scalp hair. Conversely, body hair encompasses all other types, such as facial and axillary hair.

Process Overview

The comprehensive laboratory procedure for processing drug test results comprises four crucial phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing phase, where the sample is integrated into the laboratory’s system. This includes ensuring the sample’s seal and shipment were uncompromised, generating a random LAN (Laboratory Accessioning Number), and completing any further data input absent in an electronic chain of custody system.

Screening serves as an initial, rapid examination for potential drug use. While screening is an economical approach for eliminating drugs in most samples, a positive screening result necessitates confirmation for legal acceptance. Any samples that yield a presumptive positive in the Screening stage require additional confirmation.

When a presumptive positive is noted during Screening, additional hair is extracted from the primary sample for the Extraction phase. This stage involves extracting drugs from hair at much lower concentrations than other methods (such as urine or oral fluid), which renders hair drug screening notably challenging.

Confirmation for any positive screening outcome utilizes techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if needed. The full laboratory procedure, spanning from Accessioning to Confirmation, upholds the CAP (College of American Pathologists) Hair certification along with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing can identify drug use for up to 90 days, whereas urine tests have a more restricted timeframe.
• Challenging to falsify: The complexity of evading hair drug tests enhances result accuracy.
• Offers chronological insights: It provides a historical pattern of substance use over time, rather than merely identifying recent consumption.

Limitations:

• Inability to detect recent intake: It generally requires 5-7 days for substances to be traceable in hair.
• Higher Cost: Hair testing tends to be costlier compared to alternative drug testing techniques.
• Result variability: Elements like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Despite common reference as "hair follicle tests", the analysis is actually conducted on the hair strand rather than the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
