Abstract : 

Introduction: At community pharmacy, determinations of analytical parameters are made more and more frequently. The values obtained are particularly useful in Pharmaceutical Care work. One of them, blood creatinine, can be especially useful for the detection and monitoring of chronic renal disease. In addition, it would allow to suggest to the clinician the deprescription or dose adjustment of certain nephrotoxic or renal elimination drugs according to the calculated glomerular filtrate. The usefulness of a new device, the StatSensor Xpress Creatinine® by Nova Biomedical, is being considered as a preliminary step to carrying out a study on the possibility of implementing a professional service with these characteristics.

Material and methods: From a blood sample provided by one of the researchers and a creatinine control solution, 35 samples are prepared and analyzed with the test device. Another 35 aliquots of the former are analyzed by a reference laboratory. Accuracy, diagnostic performance and precision are evaluated using the Passing Bablock, Lin correlation coefficient, Bland Altman, diagnostic sensitivity and specificity, and coefficient of variation tests.

Results: The Passing Bablock test and the Lin coefficient are correct. Bland Altman is statistically significant at values greater than 5 mg/dL. Diagnostic sensitivity and specificity are 100% and the coefficient of variation is less than 5%.

Conclusion: The StatSensor Xpress Creatinine® Handheld Analyzer is valid in the range of common community pharmacy values
