filtration fraction


Also found in: Wikipedia.

fil·tra·tion frac·tion (FF),

the fraction of the plasma entering the kidney that filters into the lumen of the renal tubules, determined by dividing the glomerular filtration rate by the renal plasma flow; normally, it is around 0.17.

Present study shows filtration capacity (urea nitrogen and creatinine) of AN 69 dialyzers are double than the PAES filters, which could be due to larger surface area proportionate with filtration fraction (Prismaflex).
In the second step gel filtration fraction 7 showing a more intense activity 1 band than activity 2 was passed through a Q Sepharose ion-exchange column.
