Is the urine spot protein/ XXXX ratio a valid diagnostic test for @entity1468 ?

@entity1 @entity644 @entity101 @entity1468 @entity1011
The objective of this study was to assess the value of the spot protein/ @entity1011 ratio as the diagnostic test for @entity1468 by correlating it to the 24   h urine protein. For the spot test, this study uses the cut-off value recognised by the International Society for the Study of @entity101 in Pregnancy (ISSHP). Ours was a correlational study made in the setting of the antenatal assessment unit/antenatal ward in a District General Hospital. @entity1 at>24 weeks' gestation with @entity101 and>1+ @entity644 (n=32) were included in the study. A 10   ml sample of urine was collected for the spot protein/ @entity1011 ratio (PCR) before the 24   h collection was started. Spot PCR samples were stored at -18  C until the end of the study period. The results of the spot PCR were correlated to 24   h results using Pearson's correlation coefficient. Main outcome measures were correlation coefficient, sensitivity, specificity, positive and negative predictive values. Correlation was significant (r(2)=0.82). Sensitivity, 83%; specificity, 92%; positive likelihood ratio, 10.3; negative likelihood ratio, 0.18. The spot PCR correlates well to the 24   h urine protein. The new cut-off values recognised by the ISSHP are producing consistent results. The evidence in favour of the spot PCR needs to be reassessed by larger studies.
