Comprehensive Metabolic Panel (Definition)

The comprehensive metabolic panel (cmp) is a panel of blood tests that serves as an initial broad medical screening tool. The cmp provides a rough check of kidney function, liver function, and electrolyte and fluid balance. The cmp is an expanded version of the basic metabolic panel (bmp), which does not include liver tests. A cmp (or bmp) is usually ordered as part of ...Read more

I have had a  nephrectomy due to renal cell carcinoma in 2011. My CMP=  creatinine 1.72, GFR 31, ALT 68, AST 45. are ^ numbers due to diabetes/kidneys?

Nephrectomy: ...will reduce kidney function in half resulting in increased serum creatinine (Cr) and reduced (GFR). With time the kidney compensates through hypertrophy, and these numbers partially normalize. Your numbers are not normal suggesting another cause of kidney dysfunction, possibly from diabetes, if there is a longstanding history of this. The increased AST and ALT suggest mild liver dysfunction. ...Read more

Hi in my cmp test says bun/creatinine ration not applicable?What does it mean?Bad or good?

Hi in my cmp test says bun/creatinine ration not applicable?What does it mean?Bad or good?

Means not done: Not important. BUN & creat are what you need to have normal. It could be because one of the numbers is reported as "less than" e.g. BUN < 5 (less than 5). In this case you cannot calculate the ratio since you cannot use 5. The issue is not important anyways. You do not seem to have a kidney disease. ...Read more

Get weekly CBC & CMP to monitor kidneys as I'm on a lot of meds. BUN/Creatinine Ratio has been elevated and was 30:1 last week. Should I be concerned?

Get weekly CBC & CMP to monitor kidneys as I'm on a lot of meds. BUN/Creatinine Ratio has been elevated and was 30:1 last week. Should I be concerned?

Depends: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, it would have been more useful to know the actual values than just the ratio. Drink plenty of water before you repeat the test next week. ...Read more

I have lupus -but my doctor never checks me urine ;but she does a cbc, cmp, esr, complements, cpk, bun, and creatinine. Should i be concerned w/ no ua?

Urine in lupus: Lupus is known to affect the kidneys, however, not in every patient. If there is a concern that your kidneys are affected, you doc should check your urine. It sounds she checks your kidney function by way of creatinine, so she monitors kidney function already. If you have any symptoms related to your kidneys - frequency, urgency, bloody/cloudy urine you need to bring them up to your doc. ...Read more

Which elements on a standard CMP or other test could suggest dehydration?

Which elements on a standard CMP or other test could suggest dehydration?

Multiple: On a CMP, a high BUN-to-creatinine ratio MAY be suggestive of dehydration. On a review of urine electrolytes, a low urine chloride or a low FENa may also suggest this. But the operative word is SUGGEST, as there are many causes of a high BUN:Cr and low FENa. To actually put context to these labs, it is always advisable to seek your physician to interpret them properly and apply them to your case. ...Read more

Can one have hepatic encephalopothy while cmp and lft bloodworks are normal?

Possible but: not very likely, at the very end stage of liver disease liver enzymes could be normal not because liver is normal but because there is no cell left to produce them so LFT could be normal but Bilirubin is never normal, and usually there is electrolytes abnormality with low sodium and potassium. ...Read more
