Answer

Proteinuria is typically one of the presenting symptoms in patients with eclampsia. A timed collection has been the criterion standard for urinalysis to detect proteinuria (>300 mg/24 h or >1 g/L). Protein per unit time measured over 24 hours has been used traditionally; however, 12-hour collections have proved to be as accurate. [14] . In addition, it is now common to rely upon a spot protein to creatinine ratio to assess proteinuria, instead of a timed collection. The degree of proteinuria or change in proteinuria is helpful in diagnosing preeclampsia, but does not have any significant effect on clinical management.
