Hepatic Enzyme Activity Testing in Feed Additive Safety Studies
The hepatic enzyme activity testing is a critical component of feed additive safety studies. This assessment evaluates the potential impact of feed additives on liver function enzymes, which are crucial for various physiological processes including metabolism and detoxification.
Ensuring that feed additives do not adversely affect these enzymes is essential to guaranteeing animal health and welfare during production phases. Liver enzyme activities such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) are routinely monitored in toxicological studies.
Our laboratory offers comprehensive hepatic enzyme activity testing services, which include the analysis of various enzymes that are indicative of liver health. This service is particularly valuable for those involved in quality management, compliance officers, R&D engineers, and procurement personnel responsible for ensuring feed safety and efficacy.
The primary goal of this test is to identify any adverse effects on hepatic enzyme activity caused by new or existing feed additives. The results help determine the appropriate dosage levels and potential side effects associated with these additives in animal feeds.
For accurate testing, blood samples are collected from animals according to predefined protocols established within the study design. These samples undergo rigorous analysis using advanced analytical instruments that provide precise measurements of hepatic enzyme activities.
The laboratory adheres strictly to international standards such as ISO 17025 for quality assurance and ISO/IEC 17026 for proficiency testing, ensuring reliability and accuracy in all our tests. Compliance with these stringent requirements guarantees the validity of results presented in peer-reviewed journals or regulatory submissions.
Our team utilizes state-of-the-art equipment to perform hepatic enzyme activity tests on feed additives. These tests involve multiple steps including sample preparation, incubation periods, colorimetric reactions, and spectrophotometric measurements.
The process begins with careful collection of blood samples from the test animals, followed by centrifugation to separate plasma or serum containing the enzymes under investigation. Afterward, appropriate reagents are added to initiate enzymatic reactions leading to specific colors whose intensity directly correlates with enzyme activities measured via spectrophotometry.
| Enzyme | International Standards | Description |
|---|---|---|
| Alanine Aminotransferase (ALT) | ASTM E1592-07, ISO 6198:1995 | An indicator of hepatocellular injury; involved in amino acid metabolism. |
| Aspartate Aminotransferase (AST) | ASTM E1592-07, ISO 6198:1995 | Also a marker for hepatocellular damage; plays roles in amino acid and carbohydrate metabolism. |
| Alkaline Phosphatase (ALP) | ASTM E1592-07, ISO 6198:1995 | Associated with bile secretion; also found in bones and intestines. |
The testing procedure requires meticulous attention to detail throughout each step of the process. Our highly trained technicians follow standardized protocols meticulously, ensuring consistent and reliable results. This approach not only enhances data accuracy but also facilitates easier interpretation by regulatory bodies or clients involved in feed additive development.
Understanding how different factors influence hepatic enzyme activities is paramount when conducting comprehensive safety assessments on potential new feed additives. By accurately measuring these parameters through rigorous laboratory methods, we provide valuable insights into the potential risks associated with specific compounds used in animal feeds.
Applied Standards
