The Protein to Creatinine test is a newer and more efficient way to screen for preeclampsia. Protein is present in higher levels in women with preeclampsia. Called proteinuria, the condition can be measured alone in a 24 hour urine sample which can be time consuming and impractical in settings with large numbers of patients or patients coming from far away and needing to return home.
A newer method called the protein to creatinine (PrCr or P/C test) is predictive of proteinuria >1. This method assesses the ratio of protein to creatinine in the urine.
This test, called the 'spot-check' is a faster way to assess likelihood or preeclampsia and to identify women who will need monitoring and follow-up. A study in Turkey showed that "the urine spot P/C ratio above 0.9 mg/mg strongly predicts significant proteinuria of more than 1 gram. In this published 2015 study, it is recommended that the P/C ratio test be used to assesspoor clinical status in order to prevent any delay in the implementation of treatment.
