The creatinine levels in both urine and blood are determined and compared. Normal creatinine clearance for healthy women is 88-128 mL/min. and 97 to 137 mL/min. in males (normal levels may vary slightly between labs). Blood urea nitrogen (BUN) level is another indicator of kidney function.he creatinine levels in both urine and blood are determined and compared.

Modern theories speculate that the stones were dragged by roller and sledge from the inland mountains to the headwaters of Milford Haven. The Bluestones came from the Preseli Mountains in Wales. They are much smaller than the Sarsen stones.
