My labs came back and my bun/ creatinine was 23. ?

My labs came back and my bun/ creatinine was 23. ?

Bun/creatinine ratio: This is only mildly elevated. If all other labs are normal and you are urinated a normal volume, likely cause is dehydration. followup with your doctor if symptoms persist or worsen ...Read more

Probably normal: It is perfectly normal for 5% of the population to be a bit outside of the "normal" lab values. Unless you are far outside of the norms or know that your values are changing significantly over time there is little to worry about. It is reasonable to recheck mildly abnormal labs in a few months. That value may be your normal value and not indicative of any problem. ...Read more

In Sep my eGFR was 70 with creatinine of .88, started Spiro in Jan, now numbers are 49 eGFR and 1.2 cr. Dose cut in half, labs the same. Should I worry?

Rise of creatinine: You should see a nephrologist (N) to find the cause of your acute rise of creatinine (C). It may be due to causes other than Sprio (S). Causes of acute rises of C are nephrotoxic agents and obstruction, among others. See a N to get an answer to your question. Good luck. ...Read more

Can Ccr be 9.7 ml/min if S.Creatinine is just 2.37 mg/dl? S. Cr is consistent for 3 yrs. Does that mean I need dialysis, or it may be lab error?

Subscientific: This pathologist doesn't believe in the "estimated GFR's" from spot creatinines. The idea of dialyzing somebody with a creatinine 2.3 is bolt stupid. I'll bet your nephrologist -- if you've even been referred -- will tell you the same thing. Just watch your diabetes and your hypertension and hopefully we can keep this under control. ...Read more

EGFR limitations: You seem to be concerned with your varying estimated GFR (egfr) levels. You lab data shows only creatinine (levels). To find out your actual kidney function see a nephrologist (n) and have a 24 hour urine collection for a c clearance. This will give you your actual level of renal function, not an estimate. A n will let you know if you should or should not be worried about your kidney function. ...Read more
