Hair Follicle Drug Testing - Carlock, IL

What it is, How it works

Hair testing is now recognized as an effective method for detecting drug and alcohol consumption. Hair strands capture biomarkers within their growing fibers, providing a long-term record of alcohol and drug use. By collecting hair near the scalp, one can achieve a detection period spanning up to about three months for various substances. Hair collection is straightforward, challenging to tamper with, and convenient to send.

A sample size of 1.5 inches, containing approximately 200 strands near the scalp, amounts to 100mg, which is optimal for screening and confirmation tests. For EtG tests, add-ons, or tests involving more than 10 panels, 150mg of the sample is advised. It's recommended to measure the sample's weight using a jeweler's scale. In cases where scalp hair is not accessible, an equivalent amount of body hair is acceptable. "Head hair" pertains solely to scalp hair, while "body hair" indicates all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is entered into a lab's system. This step verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any outstanding data entry not handled by an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. While cost-effective in ruling out drug usage in most samples, a positive screen requires confirmation to be valid in court. Samples testing positive in Screening necessitate secondary confirmation.

Should a sample be positive during Screening, additional hair is extracted from the original sample for Extraction. This step isolates drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug screening is notably complex.

Confirmation of any positive screen is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation as necessary. The full lab process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests reveal drug use spanning up to 90 days, whereas urine tests capture a shorter window.
• Low susceptibility to cheating: Manipulating a hair drug test is notably challenging, enhancing result accuracy.
• Offers historical insight: It illustrates drug use patterns over time, beyond just recent consumption.

Limitations:

• Not suited for recent detection: It typically takes 5-7 days before drugs become traceable in hair.
• Expense: Generally, hair drug tests have a higher cost compared to other methods.
• Result variances: Variables like hair color and individual hair growth rates can influence metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests," the analysis actually examines the hair strand and 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.
