Stability of simulated body fluids such as blood plasma, artificial urine and artificial saliva

The result of the work is answer to the question concerning the stability of the tested liquids. All tested simulated body fluids incubated at 36 °C above the week demonstrated changes in pH and ion concentration. The largest change was observed with calcium ions which plays a crucial role in the hydroxyapatite growth during the artificial blood plasma application. Furthermore only in a few cases storage of fluids at 5 °C did not significantly affected their stability.
