Actually all you have to do is add your enhancement solution once converting 0.8% to 3%. After concentration you can use what ever enhancement you want. 2 drops LISS, PEG, Albumin, NISS, so it is not about the enhancement, you add that to your cell solution. 2 drops patient plasma, 2 drops enhancement. Not to mention you can just add 1 drop LISS following decanting the 4 drops of washed cells.
