Hair Follicle Drug Testing - Hadar, NE

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands encapsulate biomarkers within the growing fibers, providing an extended profile of substance use. Collected near the scalp, hair offers a detection period of up to roughly 3 months for alcohol and drugs. It is straightforward to collect, relatively resistant to tampering, and convenient for transport.

A sample measuring 1.5 inches, comprising approximately 200 hair strands (similar in size to a #2 pencil) near the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or testing beyond 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale to weigh the sample accurately. If scalp hair cannot be obtained, a similar volume of body hair can be used. When mentioned, head hair refers exclusively to scalp hair. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

There are four pivotal steps in the laboratory assessment of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage where a sample is integrated into a lab’s system. This involves confirming that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and entering additional data not covered by an electronic chain of custody.

Screening is a preliminary examination for drug abuse indicators. While it’s a cost-efficient method for eliminating drug use in most samples, a positive result requires confirmation to hold up in legal contexts. Presumptively positive samples from Screening necessitate a follow-up confirmation.

If the sample tests presumptively positive during Screening, additional hair is taken from the original specimen for Extraction. In this phase, drugs are extracted from hair at much lower concentrations compared to other methods (such as urine or oral fluid), which makes hair screening one of the more challenging methodologies.

Confirmation for positive screening results is handled using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples deemed presumptively positive undergo washing prior to confirmation if required. The complete lab process from Accessioning through Confirmation is examined under the standards of both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect drug use for up to 90 days, offering a longer detection period than urine tests.
• Resistance to tampering: Hair tests are difficult to manipulate, yielding more trustworthy outcomes.
• Historical usage data: They offer a record of drug use over time, rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to become detectable in hair.
• Higher cost: Hair drug tests tend to be pricier than other testing methods.
• Variability of results: Elements like hair color and growth differences can impact drug metabolite concentrations in hair.

Note: Despite being frequently referred to as "hair follicle tests," the testing 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.
