Hair Follicle Drug Testing - Marydel, MD

What it is, How it works

Hair assessments are recognized as an effective approach for identifying substance use involving drugs and alcohol. Hair captures a detailed chronological record of these substances by preserving chemical markers within the strands as they grow. When clipped near the head, hair samples can unveil consumption patterns of substances within an approximate 90-day timeframe. Collecting hair is straightforward, relatively tamper-proof, and easily transportable.

A tuft measuring 1.5 inches, consisting of roughly 200 hairs (equivalent to a #2 pencil thickness) at the scalp, constitutes the optimal 100mg specimen required for analysis and validation. For testing involving EtG, additional parameters, or exceeding 10 panels, a larger 150mg sample is advisable. We advocate for the specimen to be measured on a jeweler's scale. In the absence of scalp hair, an equivalent mass of body hair is suitable. When specifying head hair, we denote scalp hair solely. Body hair includes any other hair varieties (such as facial, axillary, etc.).

Process Overview

The primary phases in the lab-based drug testing cycle encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the foundational process of integrating a specimen into a laboratory's framework. This step ensures the sample's integrity in terms of sealing and shipping, assigns a Laboratory Accessioning Number (LAN) at random, and completes necessary manual data inputs absent in a digital custody chain system.

Screening offers an initial swift appraisal for signs of substance abuse. Although being an economical method to eliminate drug consumption on most samples, any detected positives in the Screening require assertive confirmation for legal acceptability. Samples indicated as presumptively positive during Screening necessitate further verification.

For Screening-indicated positives, additional hair is extracted from the primary sample for the Extraction stage. Here, drugs are isolated from the hair at lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug screening notably challenging.

Verification of positive results from the Screening phase employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing positive initially undergo cleaning before verification. The end-to-end lab procedure, from Accessioning through Confirmation, is scrutinized under the criteria set by CAP (College of American Pathologists) Hair standards and aligns with the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair analyses can reveal drug use for up to 90 days, in contrast to shorter detection spans in urine analyses.
• Difficult to manipulate: The challenges in deceiving a hair test result attribute to its high accuracy.
• Reveals historical usage: Offers a timeline of substance use rather than a snapshot of recent consumption.

Limitations:

• Incapable of detecting immediate use: There's a 5-7 day delay before drugs become evident in hair.
• Expense: Hair testing tends to be pricier compared to alternative drug screening methods.
• Result variability: Elements like hair color and individual growth rates can influence drug metabolite concentrations within hair.

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

Why Hair Follicle Testing Beats Urine Testing

Marydel, MD sees numerous benefits in choosing hair follicle testing over traditional urine tests. Among these, the superior detection accuracy and reliability of hair testing stand out.
