What causes high INR and low Random blood glucose?

High INR and low Random blood glucose can be caused by many reasons.

If your INR is in between 0.9 ratio and 1.2 ratio and your Random blood glucose is in between 70 mg/dl and 140 mg/dl then you need not worry as these are the normal ranges for INR and Random blood glucose 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 INR levels include:

• Liver disease
• Vitamin K abnormality
• Decreased or defective factor I (fibrinogen), II (prothrombin), V or X
• Hemophilia A and hemophilia B
• Autoantibody against a specific factor (e.g., factor VIII)

Normal range of INR : 0.9 - 1.2 ratio
