Hi all.
Not a major hot topic here but if anyone gets a chance, I'd appreciate a reply. I'm sure others on this board are going to go over their bun results too.


I just got my blood tests mailed to me. Taken last week.The only thing that kicked out of range was the BUN/CREATININE RATIO which was 28.

I got my old blood tests and here is what they said about my Bun/Creatinine Ratio

3/18/02 - 12
3/7/03 - 13.3
1/17/05 – 16.7
12/19/06 - 28
5/4/07 – 28

Hey at least I haven’t changed since 2006!!!! I remember asking the doctor (in the 12/19/06 test,(not Dr. Fred) “why is it 28? and he said “did you drink water while you fasted? And I said “Of course not”, then he said “you’re dehydrated.
The same thing happened in the 5/4/07 test. I didn’t drink the water and when I asked Dr. Fred, he said ‘that’s dehydration because all your other results (like Calcium, sodium, potassium, etc. EVERYTHING was normal. He said not to worry.
I even asked the endo at Cornell and I showed her the previous tests and she also said “dehydration”.

I just googled BUN/CREATININE RATIO just to see what the hell this test is for and I learned is for the kidneys. And because I’m diabetic, I’m always concerned of course about my kidneys. And my diet is a lot of protein and low-carb. Maybe that might affect it???

I guess I Have to start drinking those 8 glasses a day. Haven’t been doing that.


Here’s what it says on the internet………………………

1. What other tests are used with BUN to check how my kidneys are functioning?
BUN and creatinine are the primary tests used to check how well the kidneys are able to filter waste products from your blood. Your doctor may also order electrolyte tests such as sodium and potassium, or calcium to help understand how your kidneys are functioning.

2. How does BUN change with age?
BUN levels increase with age. BUN levels in very young babies are about 2/3 of the levels found in healthy young adults, while levels in adults over 60 years of age are slightly higher than younger adults. Levels are also slightly higher in men than women.

3. What is a BUN/Creatinine ratio?
Occasionally, a doctor will look at the ratio between a person’s BUN and blood creatinine to help them determine what is causing these concentrations to be higher than normal. The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration. It may also be seen with increased protein, from gastrointestinal bleeding, or increased protein in the diet. The ratio may be decreased with liver disease (due to decrease in the formation of urea) and malnutrition.


I'm almost 60 and everything was good (I'm looking into the 3.9 thryoid thing) but EVERYTHING ELSE WAS NORMAL except for this stupid bun/creatinine ratio thing.

Any thoughts??

thanks, Melody

P.S. Dr. Fred said he's going to be running blood tests on me every three months because I'm diabetic. I said "why not, so does Cornell, you can compare notes".
