CONCLUSIONS ACPA has a higher PPV for RA than IgM RF, whereas their NPV is identical. ACPA is the better choice when testing for RA in primary care. Seroconversion is rare, and it is only rarely relevant to retest. FUNDING The Department of Clinical immunology at Odense University Hospital funded the study. TRIAL REGISTRATION not relevant.

The aim of this study was to assess the performance of routine use of dipstick urine analysis during pregnancy for prediction of recto-vaginal GBS colonisation at the time of labour. METHODS Among 902 unselected Danish pregnant women, we obtained results from 1) dipstick urine analysis, 2) urine culture carried out during pregnancy, if indicated, and 3) recto-vaginal culture at labour. The inclusion criteria were age > 18 years and gestational age ≥ 37 weeks. RESULTS Intrapartum recto-vaginal GBS colonisation was predicted by a positive urine dipstick with 5% sensitivity only. CONCLUSION Dipstick urine analysis had a low sensitivity for predicting intrapartum recto-vaginal colonisation with GBS. FUNDING none. TRIAL REGISTRATION not relevant.
