Hair Follicle Drug Testing - Hunters Creek, FL

What it is, How it works

Hair testing has gained recognition as an effective approach for identifying drug and alcohol usage. Hair provides an extended record of alcohol and drug intake by capturing biomarkers within the strands of growing hair. When sampled close to the scalp, hair offers a detection window of up to approximately 90 days for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands, approximately the thickness of a #2 pencil, near the scalp, yields 100mg of hair, the optimal sample size for testing and validation. For tests such as EtG, add-ons, or panels exceeding 10, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is absent, an equivalent amount of body hair may be utilized. Scalp hair specifically refers to hair on the head, while body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory processing for a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a lab’s system, ensuring the sample was properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and completing any missing data entry that isn't covered by an electronic chain of custody system.

Screening performs a preliminary assessment for abuse drugs. While Screening is a cost-efficient method to exclude drug use for most samples, a positive result must be confirmed for it to be permissible in legal proceedings. Presumptive positives from Screening require secondary confirmation.

Should a sample test presumptively positive during Screening, additional hair is drawn from the original sample for Extraction. At this stage, drugs are extracted from hair in much lower concentrations compared to other methods (e.g., urine, oral fluid), hence hair drug screening is one of the more challenging methodologies.

Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed as necessary prior to confirmation. The comprehensive lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use up to 90 days back, whereas urine tests have a shorter detection timeframe.
• Hard to tamper: Cheating a hair drug test is extremely challenging, enhancing the accuracy of results.
• Shows historical usage: It evidences a timeline of drug use, rather than just recent activity.

Limitations:

• Cannot indicate recent usage: Drugs only become detectable in hair after roughly 5-7 days.
• Expense: Hair drug testing generally incurs higher costs compared to other testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth can influence the level of drug metabolites found.

Note: Although commonly called "hair follicle tests," the analysis 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. 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
