Good Laboratory Practice (GLP) Compliant Laboratory Services

At MVTL, we provide GLP compliant testing services to support veterinarians, study directors, contract research organizations (CROs), and project sponsors conducting regulated studies. Our laboratory verifies water safety and nutritional adequacy for animal trials, helping your research meet FDA 21 CFR Part 58 Good Laboratory Practice standards. Whether you’re managing a preclinical trial, outsourcing through a CRO, or overseeing research as a sponsor, MVTL delivers defensible results that stand up to regulatory review.

GLP Testing Capabilities

  • Crude Protein – Confirms protein levels meet study requirements for growth and health
  • Crude Fiber – Assesses digestibility and energy availability in feed
  • Moisture – Ensures feed stability and prevents spoilage or dilution of nutrients
  • Ash – Measures total mineral content for balanced diets
  • Acid Detergent Fiber (ADF) / Neutral Detergent Fiber (NDF) – Measures fiber fractions (digestibility and intake potential) to assess feed efficiency
  • Minerals – Verifies essential macro- and micro-mineral concentrations
  • Amino Acids – Confirms precise nutrient profiles needed for controlled research diets
  • Others available – Please reach out with any questions for testing that is not listed
  • Coliform/E. coli – Detects microbial contamination that could compromise animal health or confound study outcomes
  • Heavy Metals – Screens for toxic elements that can skew results or harm test subjects
  • Nitrates – Identifies levels that could impact metabolism or cause health risks
  • Sulfates – Evaluates concentrations that may affect digestion and water intake

Verifying Nutrition & Water Safety for Research Subjects

In regulated studies, maintaining control over study variables is essential. Even minor deviations in feed composition or water quality can skew clinical results and possibly jeopardize the animals or the study. MVTL provides independent verification of nutritional adequacy and water safety to give study teams confidence in controlled conditions. By confirming key nutrient levels and screening for contaminants, our GLP-compliant testing helps ensure that outcomes are driven by the treatment under study — not uncontrolled factors in the diet or environment.

MVTL Quality Manual

Data Quality & Compliance with 21 CFR Part 58

Regulators require research data to be defensible, reproducible, and collected under strict Good Laboratory Practice standards. MVTL’s processes are fully aligned with FDA 21 CFR Part 58. This provides study directors and project sponsors with results that withstand regulatory scrutiny. From chain-of-custody documentation to validated analytical methods, our team delivers the data integrity and traceability you need to meet GLP expectations and maintain confidence in your study findings.
