Hair Follicle Drug Testing - Greensboro, VT

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair acts as a timeline for alcohol and drug intake by capturing biomarkers within the threads of the hair as it grows. When taken near the scalp, hair can offer up to about a 3-month period for detecting alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and is convenient for transport.

A 1.5-inch segment comprising around 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the specimen is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair cannot be collected, a similar quantity of body hair can be obtained. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial handling of a specimen within a laboratory’s framework. It entails validating that the specimen was properly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent in an electronic chain of custody system.

Screening includes a preliminary cursory examination for drug misuse. While Screening offers a budget-friendly method to dismiss drug usage in most specimens, a positive screen demands confirmation to be accepted in legal proceedings. Any specimens deemed presumptively positive during Screening necessitate a follow-up confirmation.

If a specimen is marked as presumptively positive during the Screening phase, additional hair is taken from the original sample and readied for Extraction. Here, drugs are drawn out from hair at concentrations much lower than in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All specimens assumed positive are washed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use up to 90 days, unlike urine tests with a more limited detection span.
• Less prone to falsification: Hair drug tests are hard to manipulate, ensuring higher result accuracy.
• Reveals usage patterns: It reveals a timeline of drug consumption rather than just recent usage.

Limitations:

• Non-detection of immediate use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing tends to be pricier than other testing methods.
• Result inconsistencies: Factors like hair shade and individual differences in hair growth can influence drug metabolite concentration within the hair.

Note: Commonly termed "hair follicle tests", these tests analyze the hair strand, not the follicle beneath the scalp.
