45, female. can you interpret these numbers for me. bun 22, serum creatinine is 1.17, egfr is 56, chloride is 108, ag ratio is 2.3. can dehydration cause the elevation in the numbers or should i be concerned about my kidney function?

Labs are basically near normal, except for a lower GFR (less than normal passage of urine through the kidney), which can indicate potential damage eventually from dehydration. Get a referral to a nephrologist for guidance, and increase your hydration with clear fluids.

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. Talk to the doctor who ordered the tests. Having said that, your eGFR is lower than desired and you should consult a nephrologist. Wish you good health!

The numbers seem abnormal but it could be normal which depends on your race and body mass. If your sodium level is above 144 you may be mildly dehydrated which explain a mildly high BUN and creatinine. A repeated chemistry panel non fasting can tell use more. In general, if your kidney function is perfect, a mild dehydration with fasting for blood test should not deviate much from the baseline.
