“High blood test results?”

MCV - The normal MCV is from 80 fentoliters (fl) to 100 fl. Yours is 101. It is neglegible having .001 difference. Considered within normal limits.
MCH 34.5 - The normal value is 24 to 33 picograms (pg) of hemoglobin percent. Again a difference of .05% is considered WNL.
Creating - nl = 0.7 to 1.3 mg/dl. Your creatinine level is considered WNL. A value of great concern would be 5.0 or above for renal failure. Your value is WNL>
eGFR - 1.34 your value. It what they medical practitioner consider within normal limits (WNL)
The etiology go your bladder or what we call bladder incontinence are multiple causes. One thing to check is weakening of your pelvic floor muscles that due to general health and lifestyle changes can cause bladder leaks. There are exercises's that can help. Check with your dr. (OBGYN) Thank you.

Your MCV suggests Vitamin B12 or Folic acid deficiency, or alcohol intake, among other causes.
Your creatinine indicated renal under function, however the eGFR is probably wrong, it cannot be 1.34 with a creatinine level of 1.34. You sound like consult a urologist and or nephrologist to address your urinary issues.

The lab tests you quote are too non-specific to be diagnostic of anything. However, if you are having urinary frequency, urgency or are losing control of your urine in your bladder, the problem is not in your kidneys. The problem is in your lower urinary tract (bladder, prostate, other anatomic structures). You don't need a nephrologist (Kidney doctor); you should consult a Urologist who is a surgeon who can diagnose and deal with any of the structures that are causing the symptoms.

The serum creatinine value indicates very substantial kidney functions. As long as the serum creatinine does not increase month by month or year by year, your functions are very good. Lisinopril protects kidneys. Your bladder function will be adversely affected by hydromorphone which slows bladder emptying.
