Whenever blood is collected for a chemistry profile, a urine sample should be obtained whenever possible (especially on the initial sampling). The increase in blood phosphorus level secondary to kidney failure stimulates the parathyroid gland to increase the blood calcium level by removing it from bones. Faced with this increase, clinicians need a better understanding of what an elevated serum creatinine level represents and a simple codified approach to evaluating renal failure. In most people, uremic symptoms develop when a urine test called a creatinine clearance (CrCl) falls below 10 milliliters per minute (mL/min). Sampling is usually done in the morning in the hospital.
