Chronic Renal Failure - Blood Picture - Introduction
Elevation of urea, creatinine and uric acid are seen in renal failure. Ca+ is usually low, but may be elevated due to secondary hyperparathyoidism. Electrolyte levels depends upon renal function, salt and water intake, and use of diuretics. Na+ will be low, if water intake exceeds excretion. K+ may rise because of acidosis & use of antikaliuretic drugs (spironolactone & triamterene). Alkaline phosphatase is marginally raised.
