Saliva to Serum Potassium Correlations

Correlation of Saliva and Human Blood Serum Potassium Results

The Cardy results are reported in ppm (parts per million), so saliva results are calculated by multiplying the saliva potassium measurements on the Cardy Potassium Meter by 0.026 to convert the values from ppm to mmol/L.

The correlation results are based on normal human ranges for blood serum as 3.5 - 5.5 mmol/L and for saliva as 8 - 40 mmol/L. The saliva values, as measured by the Cardy K+ meter, have proven accurate when compared to serum values drawn and processed in labs.
