<prompt> In a pregnant female with BP 150100 mm Hg, a proteincreatinine ratio of ___ suggests development of pre-eclampsia0.200.300.200.30  <response>: Ans. is b, i.e. 0.30Ref. Fernando Arias 4e, p 189In patients with gestational hypertension, there are high chances 15-25 of progressing to pre-eclampsia. Pre-eclampsia is heralded by the development of proteinuria.Proteinuria 2 in a random urine sample is diagnostic of pre-eclampsia in these patients. When proteinuria is 1 or traces, it is necessary to send random sample to lab for determination of protein creatinine ratio and calcium creatinine ratio.Proteincreatinine ratio 0.30- indicates pre-eclampsiaCalciumcreatinine ratio 0.06- indicates pre-eclampsiaAlthough the gold standard would be measuring protein in 24 hours urine sample, but it is cumbersome.
