Biochemical Diagnosis: A Key to Accurate Medical Testing
Biochemical diagnosis involves enzyme reactions or antigen-antibody interactions, primarily used to measure biochemical indicators, body function markers, and various proteins like enzymes, sugars, lipids, non-protein nitrogen, and inorganic elements. This method is essential in detecting and monitoring various medical conditions.
As the first automated detection method, biochemical diagnosis remains one of the most widely-used techniques in in vitro diagnostics (IVD) today.
At J&K Scientific, we provide high-quality substrates, surfactants, preservatives, and other essential products to support companies in their R&D and production processes. Our solutions help maintain the reliability and accuracy of biochemical diagnostic tests.
