Which ONE of the following is the next best step here?
Complement levels (C3, C4)
Our data so far does not suggest a nephritic syndrome, let’s hold off on checking the complement levels for now. Pick again!
Human immunodeficiency virus (HIV) antibody
Good choice, the test is negative.

In this patient with nephrotic range proteinuria, kidney biopsy may provide additional information. But there’s a cheaper, less invasive test that might help us first…
Hm, not the best test here. This test might be ordered in patients to look for acute interstitial nephritis, but it’s not a great test there either. Try again!
