WebConversely, para-aminohippurate (PAH), is a non-harmful substance also used to test kidney function. Since PAH is both filtered and secreted by the kidneys, and 90% is removed from the blood on a single pass through the kidney, the clearance of PAH is often used to estimate renal blood flow (the amount of blood going through the kidneys per ...
WebSo to measure true renal plasma flow, the amount of plasma that flows into the kidney, we can use para aminohippuric acid – or PAH. That’s because PAH isn’t made in the body, so a known amount of PAH can be injected into the body. PAH is also ideal because it doesn’t alter renal plasma flow in any way. discount landscaping bricksWebJan 1, 2024 · PDF On Jan 1, 2024, DM Vasudevan and others published Chapter-25 Kidney Function Tests ...
