| Objectives | |
| Narrative objectives1 | 1.The effectiveness of calcium-ion containing beverage and the calcium-ion rich wafer in preventing hypocalcemia induced by citric acid will be investigated by measuring the serum levels of ionized calcium and observing for the presence or absence of symptoms
2.The changes in the serum ionized calcium levels will be evaluated according to the blood donors' features, in an attempt to implement more effective preventive measures |
