Hair Follicle Drug Testing - Valley Ford, CA

What it is, How it works

Hair assessments have increasingly been recognized as an effective method for identifying drug and alcohol usage. Hair offers an extended history of alcohol and drugs by embedding biomarkers within the fibers of the growing hair. When harvested near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and drugs. It is easy to gather hair, moderately hard to tamper with, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the width of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample for screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler's scale to measure the specimen is suggested. If scalp hair is lacking, a comparable quantity of body hair may be utilized. When discussing head hair, we are specifically referring to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The primary stages in the laboratory handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning means the initial incorporation of a sample into a lab's framework. This entails confirming the sample was sealed and dispatched properly, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any remaining data input not covered by an electronic chain of custody system.

Screening is a preliminary swift evaluation for drugs of misuse. Although Screening is a budget-friendly method to eliminate drug use in most samples, a positive screen must be verified for court approval. Any samples deemed presumptively positive in Screening mandate a subsequent confirmation.

When a sample is presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. At this point, drugs are isolated from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), hence hair drug screening is the most challenging method to execute.

Verification of any positive screen outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as needed. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair category and the compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can recognize drug use for up to 90 days, as opposed to urine tests which offer a shorter detection period.
• Challenging to falsify: It is extremely challenging to falsify a hair drug test, which makes the findings more reliable.
• Delivers historical information: It can depict a pattern of drug usage over time, not just recent consumption.

Limitations:

• Unable to identify recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug evaluations are typically costlier than other drug testing techniques.
• Result variations: Elements such as hair color and personal differences in hair growth can influence the level of drug metabolites in the hair.

Note: Often termed as "hair follicle tests", these tests actually analyze the hair strand and not 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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
