pH levels are particularly useful in the evaluation of stones, infection, and renal tubular acidosis (RTA). For example, in a patient with neph- rolithiasis,

Question 14

Specific gravity is associated with what?

Answer 14

specific gravity is reflective of hydration status; however, it can be inaccurate.
