Answer 1

Comments

Trust your doctor, it's normal.

Answer 2

My husbands Dr just called and said his BUN is 90..creatinine is 3.6. What symptoms should I be aware of with values like this. He has stage 4 kidney failure

Comments

Hello, kidney failure 4 will be a problem in multiple systems. For example, dyspnea caused by acute left heart failure, severe hyperkalemia is life-threatening, gastrointestinal bleeding causes hematemesis or blood in the stool, and mental problems caused by central nervous system disorders. It is recommended to check the relevant indicators frequently and regularly.

Thank you, very helpful!

Answer 4

My bun / crea level is 25. What does this mran?

Comments

Hello, BUN / creatinine is of little significance, mainly depends on whether the absolute values of urea nitrogen and creatinine are normal. The magnitude of BUN / creatinine is affected by exercise and high protein diet.

As long as your serum creatinine is normal, you're okay.

Answer 5

Bun is 30/ creatinine is 1.14/ ratio is 26.3 - what does this mean?

Comments

your serum creatinine is normal . No need to worry about kidney function. Possible case of High ratio are as follow:
1 Alienation: hyperthermia, taking steroids and tetracyclines, stress, etc.
2 high protein diet (especially when renal insufficiency), gastrointestinal bleeding.
3 urea reabsorption hyperthyroidism: pre-renal, dehydration, cardiac insufficiency, hypoproteinemia, decreased blood volume, hepatorenal syndrome. Post-renal: urinary tract obstruction, ureteral anastomosis. Kidney tubular urea permeability congenital hyperactivity (familial hyperurea).

Answer 6

My doctor keeps me having my blood checked every 2 weeks because she keeps getting different readings about my kidney numbers, should I be looking into this further? These are off 3 different draws.

Glucose 128,101,113,90

Creatinine 2.31,1.06,1.02

BUN 45,21,32  Why are my levels so up and down?

Comments

I do not know why it goes up and down,  but I am happy to see that your creatinine is getting down. The smaller this value, the stronger your kidney function.
OK, I wanna dig further. What condition/symptom causes you to see your doctor? Why does your doctor keep measuring your kidney function? Were all the three tests done before breakfast?

Answer 7

the only thing I want is:

What is normal for BUN

What is normal for Creatinine

Comments

my BUN is 33
My Creatinine is 2.7
Please help I only need to know what is normal

Normal BUN values tend to vary depending on gender and age. It’s also important to note that each laboratory has different ranges for what’s normal. In general, normal BUN levels fall in the following ranges: adult men: 8 to 24 mg/dL. adult women: 6 to 21 mg/dL. children 1 to 17 years old: 7 to 20 mg/dL.

Normal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dL) in adult males and 0.5 to 1.1 milligrams per deciliter in adult females.
