Table 1 : Effects of potassium adsorption filter methods A and B on
potassium concentrations in red blood cell solutions.

	Irradiated RBC #1	Irradiated RBC #2	Irradiated RBC #3
Saline-filled method (method A, N=4)	92.7±0.1%	93.1±0.0%	89.7±0.1%
Saline-removed method (method B, N=4)	96.8±0.0%*	95.8±0.0%*	95.1±0.0%*

RBC: Red blood cell solution
The potassium concentration of RBC#1 (AB type, Rh D+, day 25),
RBC#2 (AB type, Rh D+, day 24), RBC#3 (AB type, Rh D+, day
24) prior to passing through PAF was 54.0±1.0 mEq/L, 62.8±2.8
mEq/L, 60.0±0.4 mEq/L, respectively.
Data represent the means±standard errors.
