Diagnosis & Tests
During an examination, your health care provider may find the following signs:
* High blood pressure
* Signs of fluid overload (when examining the abdomen)
* Enlarged liver
* Abnormal heart and lung sounds
* Enlarged neck veins from increased pressure
* General swelling
* Signs of acute kidney failure
Tests that may be done include:
* BUN
* Creatinine
* Creatinine clearance
* Urinalysis
* Urine appearance and color
* Potassium test

A kidney biopsy will reveal inflammation of the glomeruli, which may indicate the cause.
Tests to determine the cause of acute nephritic syndrome may include:

* ANCA (antineutrophil cytoplasmic antibody for vasculitis)
* Anti-glomerular basement membrane antibody
* Blood culture
* Culture of the throat or skin
