Hair Follicle Drug Testing - Yucca Valley, CA

What it is, How it works

Hair testing is now widely regarded as an effective method for identifying drug and alcohol consumption. Hair can capture a record of alcohol and drug use by embedding biomarkers in the fibers of the hair as it grows. When hair is collected near the scalp, it provides a detection span of up to about three months for alcohol and drugs. The collection process is straightforward, it is not easily tampered with, and it is convenient to transport.

Collecting a sample of approximately 200 strands (equivalent in size to a #2 pencil) from the area closest to the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG testing, additional panels beyond 10, or other add-ons, a 150mg specimen is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair cannot be collected, a proportional amount of body hair can be taken. "Head hair" refers only to scalp hair, while "body hair" includes all different hair types (facial, axillary, etc.).

Process Overview

The primary stages in the laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the first steps in processing a sample through a lab’s system. This step checks if the sample was sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and finishes any extra data entry not covered by an electronic chain of custody system.

Screening performs an initial, rapid assessment for drug use. While Screening offers a cost-efficient method to eliminate drug use in most samples, any positive screen must be verified to be legitimate in court. Samples that return a positive result in Screening must undergo a follow-up confirmation.

In cases where a sample tests positive in the Screening phase, more hair is drawn from the original sample for Extraction. During this phase, drugs are isolated from hair at a much lower concentration compared to other techniques (such as urine or saliva), making hair drug screening one of the hardest approaches to conduct.

To confirm positive screening outcomes, GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed. All samples with presumptive positive results are cleaned before confirmation is done, when applicable. The end-to-end lab process, from Accessioning to Confirmation, is subjected to audit under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, while urine tests have a shorter detection period.
• Difficult to manipulate: Manipulating a hair drug test is very hard, which ensures more precise results.
• Offers historical insights: It showcases a drug use pattern over time rather than just recent consumption.

Limitations:

• Cannot detect recent usage: Drugs take around 5-7 days to become detectable in hair.
• Expense: Generally, hair drug tests cost more than other drug testing methods.
• Results variability: Hair color and individual hair growth differences can influence the drug metabolite levels in hair.

Note: Although frequently called "hair follicle tests", the analysis focuses on the hair strand, not the hair follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
