Prerenal Azotemia Diagnosis & Tests
An examination may show signs of low cardiac output or signs of hypovolemia. The blood pressure may be low or may drop when the person stands up. The pulse pressure (difference between systolic blood pressure and diastolic blood pressure) may be reduced. The heart rate may be rapid.
Skin turgor may be poor, with dry mucous membranes. The neck veins may be collapsed. There may be little or no urine in the bladder even when drained by a catheter. If the condition is prolonged, other signs of acute renal failure may be present.
A urinalysis may show decreased kidney function preserving the ability of the tubules. Nitrogen wastes and electrolytes continue to be excreted, but at abnormally low rates.
Blood lab tests show a rapid accumulation of nitrogen wastes: - Increased BUN
- Increased creatine
- Increased BUN/creatinine ratio
