My egfr count is 99.57 and i am 23-year-old adult, as per internet my egfr should be around 116 but its low and now i am scared?

GFR is not a count but an estimated filtration rate for kidneys and that is heavily dependent on the level of hydration at the time blood is drawn, as context may make a huge difference. Your doc and not the Internet remains best in placing such results in proper context, indiscriminate Internet use exacerbates health related anxiety.

ormal GFR is within 90-140. So yours is normal. PL dont get your medical info on the internet but from your doc
