Abstract
The present paper determined the concentration of Ca 2+ ion in a sampling group that included a total of 90 patients aged from a few months to 85 years, manifesting various health conditions that have influenced the concentration of electrolytes in serum, as well as subjects of electrolyte homeostasis disturbed by the development of tumours and cysts. The investigation was conducted in two seasons, summer and winter. For determinations using the analyzer of electrolytes in the blood, there was used Model AVL 988-3, a device for determining Na +, K +, Ca2 +, Cl and Li + levels. In winter, there was a major decrease in the concentration of calcium ions: 97% of patients had concentrations below normal and only 3% normal, while in summer, 40% of patients had normal levels of calcium, 53% hypocalcemia and 7% hypercalcaemia. The results obtained constitute a warning that we need to reconsider our lifestyle, especially habits and nutrition.
