Hair Follicle Drug Testing - Dilworth, MN

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug exposure by retaining biomarkers within the hair strand as it grows. Once collected near the scalp, hair can reveal drug and alcohol use for up to around three months. Hair acquisition is straightforward, hard to tamper with, and easy to dispatch.

A 1.5-inch hair segment, consisting of roughly 200 strands (comparable in size to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for assessment and confirmation. For EtG, supplementary tests, or screening beyond 10 panels, a recommendation of 150mg is made. It's suggested to weigh the hair sample with a jeweler's scale. Should scalp hair be inaccessible, a similar amount of body hair can be utilized. Scalp hair refers specifically to the hair on the head, while body hair includes all other types (facial, armpit, etc.).

Process Overview

The process of lab processing for a drug test result encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails introducing a sample into the lab’s system. This step confirms proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any remaining data entry not automatically captured by an electronic chain of custody system.

Screening provides a preliminary analysis for drug presence. Although Screening efficiently eliminates drug use in most samples, a positive screen necessitates confirmation for legal acceptability. Samples deemed presumptively positive in Screening require further confirmation tests.

If presumptive positivity arises in Screening, additional hair is taken from the initial sample for Extraction. This process involves extracting drugs from the hair at significantly lower concentrations than alternative methods (such as urine or oral fluid analysis), which is why hair drug analysis presents the greatest challenge.

Confirmation of positive results post-Screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before necessary confirmation. The entire laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair criteria and adheres to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair testing can identify drug consumption for up to 90 days, unlike urine tests which offer shorter detection periods.
• Hard to falsify: Manipulating a hair drug test is extremely tough, thereby enhancing result accuracy.
• Tracks usage history: It charts drug consumption patterns over a duration, rather than just recent usage.

Limitations:

• Inability to detect recent usage: Drugs become traceable in hair after roughly 5-7 days.
• Expense: Hair drug testing typically incurs higher costs than alternate methods.
• Result discrepancies: Factors such as hair pigmentation and individual hair growth variations can influence metabolite concentrations in hair.

Note: Often dubbed "hair follicle tests," these assessments evaluate 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.
