Hello. is a high egfr or low urea cause for concern? if so what could be causing it? my egfr is 136, my urea of 2.3, the range is 2.5-7.8. my creatine and albumin are normal. thank you?

Low urea is either due to low protein intake or vigorous hydration, nothing to concern, unless you also have low blood sodium (Na), in that case you have to lower free water intake. I would assume you have a quite low serum creatinine too and that's why your eGFR is above normal range. High eGFR is only important in people with early phase of diabetic mellitus which is called hyperfiltration phase

None of the values you mentioned are a cause for concern. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines

Your test reports seem normal. Tests are not always on the dot. If you are otherwise well dont worry.
