Hello,
Thanks for posting on HCM
You are having a slightly elevated creatinine (normal value 1.1) but could be most probably due to an existing
kidney infection ( which could be serious).
Glomerulonephritis can lead to kidney failure.
Your doctor might be required to run some more test like
urinalysis and culture, 24hrs
proteinuria, protein
electrophoresis, fasting blood sugar, kidney ultrasound to see if they are any existing kidney lesions that could be a cause for concern.
You will have to complete your antibiotics as prescribed by your doctor. Then you can do in say a week or more a creatinine level tests to see if they are still elevated. You did not mention the level of urea ( it can also be helpful).
Hope this helps
