Creatinine was 0.94
BUN 1 point above the range
Electrolytes all within normal range
Recently increased protein/meat in diet, but I don't remember what I ate directly leading up to the test. Test was taken around lunch time and I hadn't had lunch yet but can't remember if maybe I had any meat with breakfast or maybe beef jerky (which I have sometimes as a snack) before because I wasn't really thinking about that. Wasn't dehydrated, no protein in urine but was well hydrated so could it have been too diluted to tell? I don't have diabetes or high bp (110/62 at last doctor's visit and that's a little higher than normal for me, usually closer to 100/60)
I've been taking 100mg doxycycline once a day for a while now. Only take ibuprofen occasionally/rarely (maybe one dose every couple months) I'm relatively fit but have had some muscle wasting a few months back from being a little malnourished. I feel like I have a little swelling in my legs by the end of most days (not pitting).
Cholesterol levels are good I think, at least within normal range- PCP didn't comment on them. I eat a lot of fats like almonds and avocado.
I'm about 105-110 lbs, 5'3".
I try to be very healthy and really pay attention to lab results and I know Gfr above 60 is considered normal but according to everything I've seen online, for my age it's supposed to be above 100. PCP is not concerned/ didn't even say anything until I pointed it out, but I requested to get it retested. So I just don't really understand.. Any insight as to why my gfr is (relatively) low? Could it be the general increase in eating meat lately even if it wasn't directly before the test? Really appreciate any insight.
