Hair Follicle Drug Testing - Halstad, MN

What it is, How it works

Hair examinations have gained recognition as a potent method for identifying drug and alcohol consumption. Hair encases a prolonged record of alcohol and drug intake by embedding biomarkers within the strands of the hair as it grows. When collected near the scalp, hair can reveal up to a three-month detection period for alcohol and drugs. Hair is straightforward to collect, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment consisting of about 200 hair strands (approximately the size of a #2 pencil) near the scalp yields 100mg, deemed the ideal sample for evaluation and verification. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair may be gathered. When mentioning head hair, we refer specifically to scalp hair. Body hair includes all additional hair types (facial, axillary, etc.).

Process Overview

The primary stages involved in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial handling of a sample into a laboratory’s setup. This encompasses ensuring the sample was sealed and dispatched properly, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any further data input not covered by an electronic custody chain system.

Screening entails an initial swift check for drug misuse. Although Screening is a cost-efficient method to rule out drug consumption on most samples, a positive result must be validated to be admissible in legal proceedings. Samples with a presumptively positive result in Screening do require an additional confirmation.

If a sample appears presumptively positive in the Screening phase, more hair is extracted from the initial sample and prepped for Extraction. During this phase, drugs are drawn out of hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), signifying why hair drug screening is notably complex to execute.

Confirmation of any positive Screening result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive undergo washing before confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests enable the detection of drug use for up to 90 days, compared to urine tests that have a shorter detection span.
• Hard to fake: Cheating a hair drug test is incredibly difficult, thereby enhancing result accuracy.
• Offers historical insights: It can illustrate a pattern of drug consumption over time, not merely recent usage.

Limitations:

• Inability to detect recent usage: It typically takes about 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests often incur higher expenses than other drug testing techniques.
• Result variations: Elements like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: While commonly called "hair follicle tests," the testing process focuses on the hair strand 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.
