Possibly Dehydration: Thank goodness, your kidney function is normal. But any increase bun/creatinine ratio, typically > 20 could mean that you are dehydrated. ...Read more

Hba1c-6.5, microalbumin cetatinine ratio 119mg/gm other readings are normal?

Hba1c-6.5, microalbumin cetatinine ratio 119mg/gm other readings are normal?

Proteinuria: The hba1c of 6.5% is consistent with overall good diabetes control. However, the microalbumin ratio is high, suggesting that you are leaking protein through your kidneys. This can be an early sign of diabetes affecting your kidneys. You should do a 24 hr urine collection for protein excretion to better assess this. You likely should be on a ace inhibitor or arb to help protect your kidneys. ...Read more

Creatinine level is 1.3mg/dl (range:0.8-1.3)..bun/creat ratio normal,electrolytes all normal, uric acid normal, urinalysis all normal.. any concern?

No: At your age, kidney function is usually starting to drop of. And/or you may simply be physically fit and decently muscled. When I was lifting weights daily, I ran 1.7-1.8. I see you have hepatitis C and cirrhosis. See if you can get into one of these new studies with the meds that usually cure it. Best wishes. ...Read more

Low creatinine and elevated bun/creatinine ratioplease interpret?

Stop worrying: Low creatinine is never a health concern. Reference ranges are set so that a few percent of healthies fall outside on either end. The ratio can be up if you're a little thirsty or ate a protein-rich meal lately. ...Read more

Explanations for elevated bilirubin ? (indirect high, direct normal)...also normal hemoglobin, low platelets, other liver function tests normal

Explanations for elevated bilirubin ?  (indirect high, direct normal)...also normal hemoglobin, low platelets, other liver function tests normal

Need more info: About 2-3% of otherwise normal people have elevated bilirubin, usually less than 5.0 mg/dL. Gilbert's disease is a usual cause and it despite disease in the name, it does not adversely affect a person's health. If you have any symptoms, it would be prudent to see your doctor. Consult this site for more info. http://www.mayoclinic.org/diseases-conditions/gilberts-syndrome/basics/definition/CON-20024904 ...Read more

Low creatinine and elevated bun/creatinine ratio. Please explain?

Decrease in flow.: Bun=blood urea nitrogen, byproduct of proteins ingested, if rise to high levels due to kidney problem, can cause toxic affects on the body. Creatinine= measurement of renal function. Normal bun/cr ratio about 10. The higher that ratio, the more likely it is not intrinsic kidney disease per se, but reduction in blood flow or volume to kidney, like when on strong diuretic-prerenal-reversible. ...Read more

CBC test results: Elevated MCHC, elevated MCH, bottom of range for Haematocrit, everything else within normal ranges. What do these results mean?

CBC test results: Elevated MCHC, elevated MCH, bottom of range for Haematocrit, everything else within normal ranges.  What do these results mean?

Nothing: Your physician may want to repeat them. I trust you do not have spherocytosis or if you do, that you've been worked up. At most, a reticulocye count may be in order. Sometimes the machines can be a bit mis-calibrated. High MCHC is quite uncommon and if you feel well I wouldn't be troubled. Reference ranges are set so that a few percent of healthies fall outside on either end. ...Read more

Last month ast, ALT all normal, albumin, globulin, bilirubin not normal, this month albumin, bilirubin, globulin normal but AST and ALT very high.Possible?

Yes: This is not only possible but commonplace. I believe we've met. Cirrhosis is a chaotic system and labs fluctuate based on activity (damage / healing). We're not going to know for certain, but if we could talk to your liver, i'd bet he would tell you he's regenerated a huge number of cells which is why he's working better and has more total cells though still bearing injury. Be glad. ...Read more

High value of creatinine clearance.Serum creatinine 0, 8mg/dl.Creat. Clearance 165ml/min.Normal value from 80 to130.What's the relevance of high value?

High value of creatinine clearance.Serum creatinine 0, 8mg/dl.Creat. Clearance 165ml/min.Normal value from 80 to130.What's the relevance of high value?

Don't worry: A high estimated GFR means nothing whateve except that the estimate has little to do with reality. The fad for estimating glomerular filtration rates in healthy people based on a correlation with serum creatinine is unscientific and has many pathologists and nephrologists unhappy. Ignore it. ...Read more

Need more info: Trying to give you a "heads up" on the implications of these values is like knowing the full story of a book by just reading the table of contents. The best person to give you insight about what these lab values mean is the physician who ordered them and knows a lot about your general health and background. ...Read more
