Liver Enzyme Testing in Preclinical Biotech Studies
The importance of liver enzyme testing in preclinical biotech studies cannot be overstated. In this context, liver enzymes serve as biomarkers for evaluating the potential toxicity of new biopharmaceuticals and therapeutic agents before they reach clinical trials or market release.
Preclinical research is a critical phase where safety assessments are conducted to ensure that any compound has no adverse effects on human health. Liver enzyme testing plays a pivotal role in this process by providing insight into hepatic function, which can be indicative of potential issues with drug metabolism and toxicity. This service ensures compliance with international standards such as ISO 17025 for quality management systems in testing and calibration laboratories.
Our liver enzyme testing employs advanced analytical techniques like high-performance liquid chromatography (HPLC) and tandem mass spectrometry (LC-MS/MS), which offer unparalleled precision and accuracy. These methods are essential for detecting even minute changes in enzyme levels, making them suitable for sensitive biotech studies.
The process typically involves collecting serum or plasma samples from animal models used in the study. Specimen preparation is critical; it requires strict adherence to protocols to avoid contamination or degradation of enzymes. Once prepared, these samples are analyzed using our state-of-the-art equipment to measure specific liver enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT).
Interpretation of results is done in conjunction with other safety parameters, including pharmacokinetics and toxicodynamics. This holistic approach allows us to provide comprehensive reports that are crucial for decision-making regarding the advancement of biotech products.
The acceptance criteria for this test are stringent and align with regulatory requirements. Results must fall within predefined limits set by international guidelines to ensure the compound under evaluation is safe for further stages of development.
Our expertise in this area makes us a preferred partner for biotech companies looking to streamline their preclinical assessment processes. By leveraging our advanced analytical capabilities, we contribute significantly to reducing the risk associated with early-stage drug failures due to toxicity concerns.
Applied Standards
The methodologies employed in liver enzyme testing adhere to several internationally recognized standards that govern laboratory practices and ensure reliability of results. These include:
- ISO 17025:2017 – This standard specifies general requirements for the competence of testing and calibration laboratories.
- ASTM E2386-19 – Provides guidelines for quantitative measurement by high-performance liquid chromatography with tandem mass spectrometry (HPLC/MS/MS).
- EN 17025:2017 – European counterpart to ISO 17025, ensuring compliance across different regions.
- IEC 62366-1:2014 – Relevant for the design and manufacture of medical devices, including those that interact with biological systems like pharmaceuticals.
These standards not only guide our testing procedures but also provide a benchmark against which we measure our performance. By adhering to these rigorous requirements, we ensure the accuracy and reliability of all test results produced for our clients.
