Kidney failure; Renal failure; Renal failure - acute; ARF; Kidney injury - acute
Signs and tests:
Many patients have generalized swelling caused by fluid retention. The doctor may hear a heart murmur, crackles in the lungs, or signs of inflammation of the lining of the heart when listening to the heart and lungs with a stethoscope.
The results of laboratory tests may change suddenly (within a few days to 2 weeks). Such tests may include:
A kidney or abdominal ultrasound is the preferred test for diagnosing kidney failure, but abdominal x-ray, abdominal CT scan, or abdominal MRI can tell if there is a blockage in the urinary tract.
Blood tests may help reveal the underlying cause of kidney failure. Arterial blood gas and blood chemistries may show metabolic acidosis.
