What it is

Kidneys filter extra water and wastes out of blood and make urine.[1,2]

Why it matters

Changes in kidney function can alter fluid balance, swelling, blood pressure, and urine output context.[1,2]

What it affects

  • Fluid balance is read with symptoms, weights, blood pressure, urine output, and labs.[1,2]

Interpretation traps

  • BioConst does not advise fluid restriction or diuretic changes.[1,2]
