Effects of Physiological Parameters on the Electrical Properties of Blood Bank Stored Erythrocyte Suspensions

In this study, the physiological parameters such as extracellular (SAGM+CPD+residual plasma) Na
⁺
, K
⁺
, Cl
^-
, pH, 2,3-DPG and ATP together with the Cole-Cole parameters were measured using erythrocyte suspensions from 51 male donors (31 donors form the training set and 20 donors are used for testing), on the 0
^th
, 10

, 21
^st
, 35

and 42
^nd
days of storage. Accordingly, electrical parameters were all correlated with Na
⁺
, K
⁺
, Cl
^-
, pH and ATP, at varying levels. By applying the multi-regression analysis, it is concluded that R

, R
_e
and C
_m
are appropriate for modeling Na

, K

, Cl
^-
, pH and ATP during blood bank storage and predicting blood quality
