your blood report interpretation is as follows:
1. The fasting glucose level is normal
2. Serum electrolytes sodium and potassium are within normal limits
3. Liver enzyme ALT is within normal limits
4. Creatinine is slightly raised and glomerular filtration rate is slightly decreased
So, the abnormality lies in the kidneys.
You need to consult a physician for complete evaluation of the renal system.
It may include a pelvic ultrasound, IVP, and few more tests if relevant.
