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.
