Hair Follicle Drug Testing - Clearbrook, MN

What it is, How it works

Hair analysis is a widely recognized method for identifying drug and alcohol consumption. By trapping biomarkers within the fibers of a growing hair strand, hair offers an extended historical record of substance use. Hair samples taken close to the scalp can reveal alcohol and drug usage for up to a roughly 90-day period. The collection of hair is straightforward, challenging to tamper with, and convenient for shipping.

Gathering a 1.5-inch segment of approximately 200 hair strands (comparable to a #2 pencil) nearest to the scalp equates to 100mg of hair, which is the optimal amount for both screening and verification. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is suggested. It's advisable to weigh the sample utilizing a jeweler’s scale. Should scalp hair be unobtainable, a similar quantity of body hair can be collected. By head hair, we specifically mean scalp hair, while body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

There are four principal phases in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial processing of a sample into a lab’s framework. This process includes ensuring the sample was correctly sealed and transmitted, assigning a distinct LAN (Laboratory Accessioning Number), and finalizing any essential data entry absent in an electronic chain of custody system.

Screening carries out an initial rapid assessment for drug abuse markers. Though Screening is a cost-efficient measure to exclude drug use in most specimens, a positive outcome must be verified to be permissible in legal proceedings. Samples that test presumptively positive during Screening necessitate further confirmation.

Should a sample test presumptively positive at the Screening stage, additional hair is extracted from the primary sample and readied for Extraction. This phase involves extracting substances from hair at significantly lower concentrations compared to other techniques (such as urine or saliva), rendering hair drug analysis a notably complex procedure.

The confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Every presumption-positive sample must undergo cleaning before confirmation as required. Throughout the entire laboratory sequence from Accessioning to Confirmation, all procedures are audited following both CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug assessments can identify drug consumption for up to 90 days, whereas urine assessments offer a shorter detection duration.
• Resistance to falsification: Cheating a hair drug test is highly challenging, resulting in more credible outcomes.
• Access to historical patterns: It can depict a timeline of substance consumption rather than just immediate use.

Limitations:

• Inability to identify recent use: Drugs require roughly 5-7 days to become evident in hair.
• Expense: Hair drug assessments tend to be costlier than alternative drug testing techniques.
• Result variability: Elements like hair pigment and individual growth rate differences can alter drug metabolite concentrations in hair.

Note: Despite commonly being labeled as "hair follicle tests", the test targets the hair strand itself 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. 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.
