    2016-8-6 · To determine if some wastewater properties affect the accuracy of the rapid tests on other properties (for instance, if a high pH correlated with lower accuracy for a nitrate test), we performed multiple regressions analysis using values obtained using standard methods as predictors for the absolute value of differences between standard values and rapid test values—a measure of accuracy. Values of pH obtained using test strips were less accurate at lower ammonium levels, and the inaccuracy ...
