Glomerular filtration refers to a process in the kidneys where a tiny cluster of blood vessels called a glomerulus filters out waste products and excess water from the blood, creating urine. Full definition
• Subject must meet the following criteria as indicated on the clinical laboratory tests: • Serum aspartate aminotransferase and alanine aminotransferase ≤ 2.5 x upper limit of normal (ULN) • Serum total bilirubin ≤ 1.5 x ULN • Serum creatinine ≤ 1.5 x ULN or an estimated glomerular filtration rate of > 50 mL / min as calculated by the Modification of Diet in Renal Disease equation.

Additionally, the median change in estimated glomerular filtration rate (eGFR) from baseline to week 48 favoured TAF in both studies (p < 0.01). (sciencedaily.com)
Finally, I think protein increases glomerular filtration rate, but there isn't any evidence that excessive protein actually harms healthy kidneys. (nutritionfacts.org)
