Hair Follicle Drug Testing - Emerson, IA

What it is, How it works

Hair analysis is now widely regarded as an effective method for identifying drug and alcohol consumption. Hair encapsulates a long-term record of alcohol and drug use by capturing biomarkers in the strands as they grow. When taken close to the scalp, hair can offer a detection period of up to about three months for alcohol and drugs. Hair is straightforward to collect, somewhat resistant to tampering, and simple to transport.

A 1.5-inch hair specimen, approximately 200 strands (around the diameter of a #2 pencil) nearest to the scalp, yields 100mg of hair, the preferred volume for testing. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the hair sample is advised. Utilizing a jeweler’s scale for weighing the sample is recommended. Should scalp hair be unavailable, equivalent body hair can be used. When we mention head hair, we mean scalp hair only. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four critical steps in lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial processing of the specimen into a laboratory’s system. This involves confirming the proper sealing and shipping of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.

Screening involves a preliminary rapid test for drugs. While Screening is an efficient way to exclude drug use from most samples, a positive screen must be validated to be acceptable in court. Any samples initially positive in Screening necessitate a further confirmation step.

If Screening indicates a presumptive positive, more hair is drawn from the original sample for Extraction. Here, drugs are extracted from hair at a much lower concentration compared to other methods (e.g., urine or saliva), making hair drug tests one of the most challenging methodologies to conduct.

Any positive Screening result is validated via techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as necessary. The lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests detect substance use for up to 90 days, unlike urine tests, which have a shorter detection timeframe.
• Challenging to evade: Hair drug tests are hard to manipulate, ensuring more precise results.
• Offers historical insight: It reveals patterns of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Substances become traceable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing tends to be pricier than other testing forms.
• Inconsistencies in results: Elements such as hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Though often called "hair follicle tests," the analysis pertains to 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.
