Hair Follicle Drug Testing - Manila, CA

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers in the growing strand's fibers. When taken near the scalp, it can reveal alcohol and other drug use over about a 3-month period. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

By collecting a 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil’s thickness) from the scalp, 100mg of hair is gathered—ideal for screening and confirmation. For EtG, add-ons, and/or over 10 panels tests, 150mg of the sample is advisable. We suggest weighing the sample with a jeweler’s scale. If scalp hair isn’t available, a similar volume of body hair can be obtained. Head hair refers specifically to scalp hair, whereas body hair includes all other types (e.g., facial, axillary).

Process Overview

The drug test result process in a lab includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves entering the sample into the lab system, verifying the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing extra data entry if not available through an electronic chain of custody system.

Screening is a preliminary examination for drug abuse. Although it's an affordable way to exclude drug usage in most samples, a positive result in Screening needs confirmation for legal acceptability. Samples that test positive presumptively in Screening require further confirmation.

In cases where a sample shows a presumptive positive in Screening, additional hair is taken from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair screening the most complex method to conduct.

The confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that presumptively tested positive are cleaned before confirmation if necessary. Both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards oversee the entire lab process from Accessioning to Confirmation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, contrasting with urine tests that offer a shorter detection window.
• Challenge to cheat: It's difficult to manipulate a hair drug test, ensuring more precise results.
• Historical data provision: It reveals a trend of drug use over time rather than merely recent use.

Limitations:

• Inability to detect recent use: Drugs take around 5-7 days to become detectable in hair.
• Higher cost: Hair drug tests are typically costlier than other testing methods.
• Result variations: Elements such as hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Although often called "hair follicle tests", the analysis actually examines the hair strand, 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.
