Hair Follicle Drug Testing - Carlisle, MN

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol use. Hair captures a long-term record of alcohol and other drugs by trapping biomarkers within the strands of growing hair. When collected near the scalp, hair can give up to around a 3-month detection period for alcohol and other drugs. It's easy to collect hair, challenging to tamper with it, and straightforward to ship.

A 1.5-inch sample of approximately 200 strands of hair (roughly the size of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the perfect sample for screening and confirmation. For EtG, add-ons, and/or tests surpassing 10 panels, 150mg of the specimen is suggested. It's advisable to weigh the specimen on a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair may be collected. When mentioning head hair, we specifically refer to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial intake of a sample into a laboratory’s system. This process verifies that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not provided by an electronic chain of custody system.

Screening conducts a quick initial check for drugs of abuse. While Screening provides a cost-effective method to eliminate drug usage in most samples, a positive screen requires confirmation to be accepted in legal circumstances. Any samples that test presumptively positive in Screening need secondary confirmation.

If a sample tests presumptively positive during the Screening stage, additional hair is taken from the initial specimen and prepared for Extraction. During this stage, drugs are extracted from hair at a lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening a challenging methodology to execute.

Any positive screening result undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as needed. The entire laboratory process from Accessioning to Confirmation is assessed 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 window: Hair drug tests can identify drug use up to 90 days, in contrast to urine tests that offer a shorter detection window.
• Difficulty to falsify: Cheating a hair drug test is quite challenging, resulting in more precise outcomes.
• Documents historical use: It provides a record of drug use over time, not just recent consumption.

Limitations:

• Unable to detect recent use: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are typically costlier than other drug testing techniques.
• Result variability: Factors like hair color and individual variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often called "hair follicle tests", the analysis focuses on 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.
