Hair Follicle Drug Testing - Ilchester, MD

What it is, How it works

The utilization of hair testing has emerged as a robust method for uncovering drug and alcohol consumption. Hair retains a prolonged record of these substances by capturing biomarkers within the fibers of the developing hair strand. Collected near the scalp, hair can reveal drug and alcohol use over an estimated three-month period. The collection of hair is straightforward, relatively resistant to tampering, and convenient to transport.

A 1.5-inch segment consisting of approximately 200 hair strands (roughly equating to the dimensions of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample amount for screening and validation. In cases involving EtG, test add-ons, and/or panels exceeding ten, 150mg of the sample is advised. It's preferable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a corresponding quantity of body hair can be acquired. The term "head hair" refers exclusively to scalp hair, while "body hair" pertains to all other hair types (such as facial, axillary, etc.).

Process Overview

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

Accessioning concerns the preliminary handling of a sample within a laboratory’s system. This comprises verifying the correct sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry lacking an electronic chain of custody system.

Screening constitutes an initial rapid assessment for drug abuse. While this is an economical approach to exclude drug usage in the majority of samples, a positive screen necessitates confirmation for legal admissibility. Samples presumptively positive during Screening mandate secondary validation.

When a sample tests presumptively positive during the Screening phase, additional hair is extracted from the initial specimen to be prepared for Extraction. During this phase, drugs are extracted from hair at a substantially lower concentration compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as essential. The complete laboratory process from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, contrasting with urine tests, which have a more limited detection duration.
• Resistance to cheating: Cheating a hair drug test is exceedingly challenging, thus enhancing the reliability of results.
• Offers historical insight: It reveals a pattern of drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally entail higher costs compared to alternative testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Even though often termed "hair follicle tests," the examination assesses the hair strand rather than the scalp-embedded hair follicle.

Why Hair Follicle Testing Beats Urine Testing
