A member asked:

My blood test showed "slightly elevated" bun (25mg). however, i eat a high protein diet and my dr did not tell me to fast or avoid eating protein before the test. are these results valid?

2 doctors weighed in across 2 answers

They are valid: diet does need to be taken into account, also degree of hydration

Repeat exam: and check not only BUN but also creatinine and obtain a urine analysis.
