Hair Follicle Drug Testing - Elmdale, MN

What it is, How it works

Hair testing is widely recognized as an effective means to identify the use of drugs and alcohol. By capturing biomarkers within the fibers of the growing hair strand, hair offers a prolonged timeline of alcohol and other drug usage. Collected near the scalp, hair can furnish up to a 3-month substance detection period. Its ease of collection, resistance to tampering, and straightforward shipping make it a practical choice.

A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) closest to the scalp yields 100mg of hair, ideal for screening and confirmatory purposes. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest weighing the specimen using a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair may be used. The term 'head hair' specifically pertains to scalp hair. Meanwhile, 'body hair' covers all other hair varieties (facial, axillary, etc.).

Process Overview

The drug test result processing in the lab comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary incorporation of a specimen into the lab's framework. It ensures the proper sealing and shipment of the sample, allocates a random LAN (Laboratory Accessioning Number), and concludes any pending data input absent from an electronic chain of custody system.

Screening commences with a rapid inspection for substances of misuse. While it is a budget-friendly approach to dismiss drug use in most cases, a positive screen necessitates confirmation for it to be viable in a legal context. Any samples that are ostensibly positive during Screening require an additional confirmation.

In cases where Screening indicates a presumptive positive result, further hair is extracted from the original specimen for the Extraction phase. Here, drugs are withdrawn from hair at notably lower concentrations than other procedures (such as urine or oral fluid), underscoring why hair drug screening presents a methodological challenge.

Confirmation of any positive screen outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation when essential. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can identify drug consumption for up to 90 days, whereas urine tests possess a shorter detection scope.
• Complexity to defraud: Cheating a hair drug test proves exceptionally difficult, thus heightening result precision.
• Provides historical insights: It can illustrate a pattern of drug utilization across time, rather than merely recent usage.

Limitations:

• Incapable of identifying recent usage: It necessitates roughly 5-7 days for drugs to manifest in hair.
• Expense: Hair drug evaluations typically incur higher costs relative to alternate drug testing techniques.
• Result variations: Factors like hair color and individual hair growth variability can influence drug metabolite concentrations within the hair.

Note: Although commonly termed "hair follicle tests", the analysis is conducted on the hair strand itself, 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.
