Validation of a PrCr Dipstick Diagnostic Test in Ghana

The LifeAssay Diagnostics prototype PrCr dipstick has been designed to provide the measurement of both protein and creatinine while retaining a very low estimated cost that is comparable to the current protein-only dipsticks at $0.06-0.10 per test. In 2015, an initial laboratory-based validation study of the prototype LAD PrCr test was used on more than 500 characterized urine samples from pregnant women. This validation study demonstrated comparable accuracy for detection of severe proteinuria of the LAD PrCr test to the much more expensive commercial POC test available for PrCr determination, the Siemens Multistix® PRO 10LS. These results were compared to laboratory-based reference standard assays for proteinuria measurement.
