The isolates were able to grow and degrade oxalate in the presence of 10 mM
potassium oxalate, but the degree of oxalate degradation was varied.
The
potassium oxalate gel (Group 7), on the other hand, presented a statistically significant reduction in sensitivity between the first and third weeks of evaluation.
The level of suppression of solution Zn concentrations was similar for both oxalic acid and
potassium oxalate.
This double action of
potassium oxalate may increase its possibility of combining therapies, both physical by tubular occlusion and neural by depolarizing the membrane.
Also, with the gray top drawn after the green top, neither
potassium oxalate nor sodium fluoride in the gray-top tubes would contaminate sodium or potassium testing.
