Measurement of Proteinuria
. All pregnant women should be assessed for
proteinuria. (II-2B)
19. Urinary dipstick testing (by visual or automated
testing) may be used for screening for proteinuria
when the suspicion of preeclampsia is low. (II-2B)
20. Significant proteinuria should be defined as
≥ 0.3 g/d in a complete 24-hour urine collection
or ≥ 30 mg/mmol urinary creatinine in a spot
(random) urine sample. (II-2B)
21. Significant proteinuria should be suspected when
urinary dipstick proteinuria is ≥ 1+. (II-2A)
22. More definitive testing for proteinuria (by urinary
protein:creatinine ratio or 24-hour urine collection)
is encouraged when there is a suspicion of
preeclampsia, including: ≥ 1+ dipstick proteinuria
in women with hypertension and risingblood
pressure and in women withnormal blood
pressure, but symptoms or signs suggestive of
preeclampsia. (II-2A)
23. Proteinuria testing does not need to be repeated
once significant proteinuria of preeclampsia has
been confirmed. (II-2A)
24. There is insufficient information to make a
recommendation about the accuracy of the urinary
albumin:creatinine ratio. (II-2L)
