I have a high bun/ creatinine level (28) and a low creatinine level (0.5) . Should I be concerned or do something?

I have a high bun/ creatinine level (28) and a low creatinine level (0.5) .  Should I be concerned or do something?

BUN/Creat Ratio: I personally would not worry about it since the high ratio is due to a slightly elevated BUN. This might be due to a diet high in non-essential amino acids (nothing to truly be concerned about) or a mild lack of water intake. If you are still concerned, please see your primary doctor and go over all of that with her/him. ...Read more

Follow it: Your history gives me no reason to think you have lupus. You might have taken ibuprofen, put on some extra muscle, or otherwise gotten your creatinine up for some reason. I trust your urinalysis is normal. I'd urge you to stay fit and not fret over small changes in lab values. ...Read more

31 white female, 1.2 creatinine level, normal BUN, 82 Prolaction level, 56 GFR should I be concerned?

Prolactin and kidney: Hi. Those are two unrelated conditions. Serum prolactin (PRL) can accumulate in chronic kidney disease (CKD), but your CKD is way too mild to cause that. Ergo, you have hyperprolactinemia. Do you have amenorrhea and galactorrhea? If not, the PRL may be a red herring, and macroprolactinemia should be tested for. Why you fall into the category of Stage 4 CKD is unknown to us. So, eval. PRL and CKD ...Read more

My GFR is 49 and my creatinine level is within normal levels at 12. Do i need a second opinion as my gp does not seem to be concerned.

Kidney Disease?: If your GFR was obtained by a 24 hour urine collection for creatinine clearance, you have stage 3 chronic kidney disease (ckd). You should be referred to a nephrologist (n), as at some point you will have some of the chemical abnormalities associated with ckd, these are anemia and elevation of your parathyroid hormone. You will also need to have a renal ultrasound to see the size of your kidneys. ...Read more

Should I be concerned with an Urine Creatinine level of 518.5 mg/dL, but I was dehydrated at the time of the test (just finished running 3 miles)?

Urine creatinine: No - if this was a 24 hour level - expect 14-26 mg per kg for a male fo that would be on the low side. if it was a "spot" urine - its going to be off due to the dehydration from running. I would repeat it if needed when you haven't run and are hydrated. ...Read more

Yes. You should be. : Although your creatinine level in blood is nit alarmingly high but elevated creatinine is a sensitive marker of kidney bit doing well. The high blood pressure is one of the main reasons for the kidney damage and the blood pressure should be appropriately controlled. You need to check if your urine has proteins in it.

Female white age 42. Primary hemochromatosis has caused stage 3cirrhosis. Now a urine test shows a creatintine level of 222.3. Should I be concerned?

Yes: The units are micromoles / liter, right? I'm really sorry that your hemochromatosis led to cirrhosis but the phlebotomy treatments you are receiving should at least partly reverse it. Your physician will work you up for the cause of what may be mild renal insufficiency. Some people like yourself get an IgA nephropathy secondary to liver disease; there are other possibilities. ...Read more

Is 1.03 bad creatinine level?

Creatinine: Creatinine level depends on many things....Age, race, sex, muscle mass. For women, the usual creatinine is between 0.6 and 1mg/dl. For men, between 0.9 and 1.4mg/dl. As we age, the creatinine should lower slightly (less muscle mass). The number is important but so are the trends. Usually, I am not very concerned with a creatinine of 1 unless its someone very young or very small/frail. ...Read more

How to decrease creatinine levels?

How to decrease creatinine levels?

May not need to: Lab testing isn't "one size fits all." a lab may list 1.2 as the "upper limit of the reference range", but a muscular patient can and should have a higher level. When i was lifting daily, my creatinine stayed at 1.6, and an elite bodybuilder's is likely to 2.0 or so. The level itself doesn't make you sick; it's just one piece of information to tell whether there's kidney disease. ...Read more
