Hair Follicle Drug Testing - Warrington, PA

What it is, How it works

The recognition of hair testing as an effective means for uncovering drug and alcohol use has increased significantly. Hair serves as a repository for a continuous record of substance intake by incorporating markers within the strands as they grow. A sample collected near the scalp can indicate drug and alcohol usage over a period of roughly three months. It's easy to collect hair samples, challenging to tamper with, and straightforward to send.

A segment measuring 1.5 inches, consisting of approximately 200 hair strands (equivalent to the thickness of a #2 pencil) taken closest to the scalp, yields 100mg, which is optimal for both screening and confirmation. For EtG, extended panels, or more than 10 tests, 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair isn't available, a similar quantity of body hair may be utilized. The term head hair specifically refers to scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The processing of a drug test result in the laboratory consists of four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially logged into the laboratory’s system. This phase ensures the sample is correctly sealed and transported, a unique LAN (Laboratory Accessioning Number) is generated, and additional data entry is processed in the absence of electronic custody documentation.

Screening is a preliminary evaluation for substances of abuse. While it's a cost-efficient method to exclude drug use in most samples, further corroboration is necessary for legal settings. Positive screenings proceed to a secondary confirmation.

Samples yielding positive results in Screening undergo further processing in the Extraction phase. At this stage, drugs are isolated from hair at lower concentrations than other methods (such as urine or saliva), contributing to the complexity of hair drug testing.

Positive screen confirmations are performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples suspect to be positive are cleansed as required. The laboratory process, spanning from Accessioning to Confirmation, is certified under the CAP (College of American Pathologists) Hair standard and complies with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can reveal substance use up to 90 days, in contrast to the brief detection range of urine tests.
• Challenging to falsify: Hair tests are resistant to manipulation, leading to more reliable results.
• Offers use history: It can reveal patterns of drug consumption over time instead of merely detecting recent use.

Limitations:

• Incapable of detecting recent intake: Drugs are detectable in hair roughly 5-7 days post-consumption.
• Costly: Hair evaluations tend to be pricier than other drug testing methods.
• Result variability: Aspects such as hair color and individual growth differences can influence metabolite concentrations in hair.

Note: Despite the common term "hair follicle tests," the examination focuses on the hair strand and not the subsurface follicle.

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.
