Hair Follicle Drug Testing - Kahuku, HI

What it is, How it works

Hair testing is recognized as a robust approach for identifying the usage of drugs and alcohol. The hair captures a long-term record of drug and alcohol consumption by embedding biomarkers within the strands as they grow. Collected adjacent to the scalp, hair samples can reveal drug and alcohol use over an approximately three-month timeframe. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch segment comprising roughly 200 hair strands (comparable to the girth of a #2 pencil) that is closest to the scalp equates to 100mg, which is the preferred amount for accurate screening and confirmation. For advanced tests, such as EtG, additional panels, or those exceeding 10, a 150mg specimen is advisable. We suggest measuring the sample using a jeweler's scale. If scalp hair is not an option, a similar quantity of body hair can be used. References to head hair denote only the scalp hair. Body hair signifies all other kinds of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes these four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails initially processing a sample into the lab's system, ensuring it was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and filling in any absent data not supplied by an automated chain of custody method.

Screening offers a preliminary evaluation for recreational drugs. While an efficient strategy for dismissing drug use in many samples, a positive screen must be validated to hold up legally. Any sample that tests positive provisionally in Screening needs further confirmation.

Should a sample appear positive during the Screening phase, additional hair is obtained from the original specimen for Extraction preparation. At this point, drugs are isolated from hair at significantly lower concentrations than in other testing types (e.g., urine or oral fluid), which is why hair drug testing is one of the most intricate methodologies to execute.

Any positive screening outcomes are validated using GC/MS, GC/MS/MS, or LC/MS/MS procedures. All presumptive-positive samples are cleaned before the confirmation phase if required. The entire lab workflow from Accessioning through Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug usage for up to 90 days, in contrast to urine tests that have shorter detectability spans.
• Hard to manipulate: It is exceedingly challenging to manipulate a hair drug test, providing greater accuracy in results.
• Historical data provision: It can express a recurring pattern of drug use across a set period, not just recent use.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Cost implications: Hair drug tests are typically pricier than alternative testing methods.
• Outcome variability: Variables such as hair color and unique hair growth rates can impact the levels of drug metabolites detected in the hair.

Note: Although commonly termed "hair follicle tests", the analysis is conducted 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.
