Proteins, from which plasma fractions are derived, constitute 7 percent of the plasma (including albumins, which make up about 4 percent of the plasma; globulins, about 3 percent; and fibrinogen, less than 1 percent).
Valgud, millest saadakse plasmafraktsioone, moodustavad 7 protsenti plasmast (kaasa arvatud albumiinid ja globuliinid, mis moodustavad vastavalt umbes 4 ja 3 protsenti plasmast, ning fibrinogeen, mille arvele langeb alla 1 protsendi plasmast).
