What Causes Elevated Creatinine And BUN Level In Blood?

Question: I had blood work done and had a creatinine level of 1.4 and a BUN of 14..I thought they would both be elevated with Kidney problems?
Brief Answer:
Not clear why you would think those parameters would be elevated sir
Detailed Answer:
Hello sir and welcome.
Thank you for writing to us.
I have gone through your query with diligence and would like you to know that I am here to help. Your creatinine levels are only mildly elevated, and your BUN level is within normal range for adults. Why would you think the levels would be quite elevated? I did not get that part as you have not mentioned that in your medical history or query sir.
Please do elaborate on your medical history and whether or not you are on any medications now or were on any medication, so I can better understand and help you accordingly.
Best wishes

I have been treated for the last 3 years for hypertension. My Dr. checks Kidney function from time to time..I take Metoprolol for the hypertension. I also take Buspar for anxiety. Other than the hypertension I have no medical issues. I will add, I had worked about 30 hours straight before testing and had not had anything to drink for an extended period before the blood was drawn...Could that contribute to the slightly elevated Creatinine?
