What does it mean if my bun is 22, bun creatinine 26 and creatinine serum is 0.86 ? i am a 54 yr old woman

Drink water: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your creatinine is normal. Your BUN is slightly elevated and may be because you were fasting when the blood was drawn and were dehydrated from not drinking water. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
