Simulated Body fluid recipe

I'm working on preparing **SBF** in my school's lab however a couple of components are missing which are $\ce{NaHCO3}$ (0.350 g) and $\ce{K2HPO4}$ (0.228 g) .
Is it possible to replace these components with $\ce{NaCO3}$ and $\ce{KH2PO4}$ ?


The following link has the ions concentration of SBF:

I'm not a chemist and I would really appreciate your view on this.
