Assessing the amount of protein in the urine of pregnant women is an important test in pregnancy to monitor the health of the kidneys and the whole body. Detection of proteinuria can allow for early diagnosis and intervention for complications such as preeclampsia and glomerulonephritis, which can affect the delivery process. Furthermore, proteinuria in pregnancy alone is also a risk factor. Therefore, quantitative determination of protein in the urine of pregnant women is essential.
