The test for (Non-Protein Nitrogen) NPN constituents is a diagnostic examination that measures the levels of nitrogen-containing compounds in the blood. These compounds include urea, creatinine, uric acid, and ammonium ions, which are considered waste products resulting from normal metabolic processes. Measuring NPN constituents provides valuable insights into kidney function, liver function, and overall metabolic health. In this article, we will explore the significance of NPN constituents, the tests involved, and what their levels indicate about an individual’s health.
