high blood pressure, spilling of
protein into

Most women have a "trace" amount of protein in their urine but when this arises above a certain level that suggests she may be developing preeclampsia. From the research I conducted, it was indicated that if the total content of protein in a 24h urine collect is greater than 300 mg (milligrams) then that is cause for concern.
