Hair Follicle Drug Testing - Marquette, MI

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers in the strands of the growing hair. When collected near the scalp, hair can offer up to a 3-month detection period for alcohol and other drugs. Hair is easy to gather, somewhat hard to tamper with, and simple to transport.

A 1.5-inch segment of about 200 hair strands (around the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal amount for testing and confirmation. When testing for EtG, add-ons, or over 10 panels, 150mg of hair is suggested. It’s advisable to weigh the hair on a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be utilized. "Head hair" refers to scalp hair exclusively. "Body hair" encompasses all other hair types (e.g., facial, axillary).

Process Overview

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

Accessioning pertains to the initial process of integrating a sample into a lab's system. This covers checking that the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry that an electronic chain of custody system does not provide.

Screening is a preliminary quick test for drugs of abuse. Though Screening is a cost-efficient way to rule out drug usage in most samples, a positive result requires confirmation to be valid in legal proceedings. Samples that are presumptively positive in Screening necessitate a secondary confirmation.

If a sample is potentially positive during Screening, more hair is extracted from the original sample for Extraction. During this stage, drugs are extracted from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmation for any positive screening outcome is carried out through GC/MS, GC/MS/MS or LC/MS/MS. All potentially positive samples are cleaned before confirmation as needed. The full lab process from Accessioning to Confirmation is audited 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 period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is quite challenging, making the results more credible.
• Yields historical data: It provides a drug use pattern over a duration, not just recent consumption.

Limitations:

• Unable to detect recent use: It takes around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests are often pricier compared to other drug testing methods.
• Result variability: Elements like hair color and individual hair growth differences can impact the concentration of drug metabolites in the hair.

Note: While frequently called "hair follicle tests", the test itself evaluates the hair strand and not the hair 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.
