What causes high Creatinine and low Prothrombin time?

High Creatinine and low Prothrombin time can be caused by many reasons.

If your Creatinine is in between 0.9 mg/dL and 1.3 mg/dL and your Prothrombin time is in between 12 seconds and 16 seconds then you need not worry as these are the normal ranges for Creatinine and Prothrombin time respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body.

Some examples of conditions that can increase or decrease creatinine levels include:

• Damage to or swelling of blood vessels in the kidneys.
• Bacterial infection of the kidneys (pyelonephritis)
• Conditions that can block the flow of urine in the urinary tract, such as prostate disease or kidney stone
• Reduced blood flow to the kidney due to shock, dehydration, congestive heart failure, atherosclerosis, or complications of diabetes
