Hair Follicle Drug Testing - Lime Ridge, PA

What it is, How it works

Hair testing has emerged as a potent method for identifying substance and alcohol consumption. Hair retains a prolonged history of these substances by capturing biomarkers within the strands of growing hair. When taken near the scalp, hair offers a detection window of up to about three months for alcohol and substances. Collection is straightforward, tampering is challenging, and shipping is convenient.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately as thick as a #2 pencil) near the scalp, results in 100mg of hair — the ideal sample size for initial and confirmatory tests. For EtG, add-ons, and/or tests exceeding ten panels, a 150mg sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent amount of body hair can be used. "Head hair" refers exclusively to scalp hair. In contrast, "body hair" pertains to all other types (facial, axillary, etc.).

Process Overview

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

Accessioning encompasses the initial sample handling within a lab’s system. This involves confirming the sample’s seal and shipping integrity, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any supplementary data entry outside of an electronic chain of custody process.

Screening provides a preliminary inspection for drug misuse. While cost-effective for initially dismissing drug use in most samples, a positive screening result necessitates confirmation to be valid in legal settings. Confirmation is mandatory for any samples with a presumptive positive screening result.

In cases where the Screening stage yields a presumptive positive result, more hair is extracted from the original sample for the Extraction phase. During Extraction, drugs are isolated from hair at much lower concentrations compared to methodologies like urine or oral fluid testing, attributing to the complexity of hair drug screening.

Confirmation of positive screening findings is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a pre-confirmation wash as needed. The full laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days compared to urine tests which offer a shorter timeframe.
• Challenging to falsify: Due to the difficulty in cheating, hair drug tests yield more precise outcomes.
• Historical usage data: They can establish a history of drug consumption over time, beyond recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Generally, hair drug tests incur higher costs than other testing methods.
• Result variations: Factors including hair color and individual hair growth differences can influence metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
