Hair Follicle Drug Testing - Melitota, MD

What it is, How it works

Hair drug analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair offers an extensive timeline of alcohol and substances by embedding biomarkers within the strands of growing hair. Hair collected from near the scalp can show a detection window for up to 90 days for alcohol and substances. It is easy to collect, somewhat hard to tamper with, and convenient to transport.

A 1.5-inch portion consisting of around 200 hair strands (roughly akin to a #2 pencil) nearest the scalp yields 100mg of hair, considered the optimal amount for analysis and verification. For EtG, additional tests or those surpassing 10 panels, 150mg of the hair sample is suggested. We recommend using a jeweler’s scale to weigh the specimen. If there’s no scalp hair, a comparable quantity of body hair can be gathered. By head hair, we mean scalp hair. Body hair refers to other hair types (facial, armpit, etc.).

Process Overview

The principal phases in a laboratory process for drug testing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of integrating a sample into a laboratory's framework. This is carried out by ensuring the sample is properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not facilitated by an electronic chain of custody system.

Screening entails an initial swift analysis for substances. Although Screening serves as a cost-efficient method to eliminate drug consumption in most samples, confirming a positive screen is necessary for court admissibility. Samples that test presumptively positive in Screening mandate a further confirmation procedure.

Should a sample test presumptive positive during Screening, additional hair is obtained from the primary sample and readied for Extraction. Here, drugs are drawn from hair at much lower levels than other procedures (e.g., urine or oral fluid), making hair drug screening the most intricate methodology undertaken.

Any positive screening results are confirmed through GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive samples undergo necessary washing. The lab process, from Accessioning to Confirmation, is assessed in both the CAP (College of American Pathologists) Hair setting and accreditation to ISO / IEC 17025 norms.

Benefits of hair drug screening:

• Extended detection window: Hair screening can uncover drug use for up to 90 days, whereas urine methods have a shorter window.
• Challenging to deceive: Deceiving a hair drug test is very difficult, ensuring more accurate outcomes.
• Offers historical insights: It can present a drug usage pattern over a duration, not just recent activity.

Drawbacks:

• Cannot indicate recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variations: Aspects like hair color and individual hair growth differences may influence drug metabolite levels in hair.

Note: Though often termed "hair follicle tests", the examination targets 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. 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.
