Introduction: Rapid Biophysical profile is quicker and easier to do than a full biophysical profile or a contraction stress test. Furthermore, the rBPP is regarded to be just as useful as a complete biophysical profile. Although the link between rBPP and BPP has been widely used, research is scarce. As a result, the current study looked into the relationship between the two tests, as well as their predictive ability in highrisk pregnancies. Material and Methods: 60 pregnant women with ≥ 32 weeks of singleton gestation, were randomly selected during their hospital visit. They were subjected to USG scan. NST AFI, fetal breathing, fetal tone, and fetal movement will be examined to complete the BPP test. After a 10-minute break, SPFM will be carried out by the same examiner to finish rBPP test. These results were compared with the perinatal outcome.Results: The present study showed that scores of rapid Biophysical Profile have strong positive correlation with scores of biophysical profile (r 2 = 0.531, P = <0.001) and it was statistically significant. The rapid/ modified biophysical profile test is 78% sensitive to Biophysical profile test, which means 78% times the function can identify the cases and classify correctly, as diseased cases with PPV of 61%.
Conclusion:The statistically significant positive correlation between rBPP and BPP has been revealed. Due to its simplicity, rapidity, less expensive and no need for experience interpreter, the rBPP can be used as a primary screening antepartum fetal surveillance in the overcrowded obstetric center.
