Abstract
Objective: The objective of the study was to evaluate the efficacy of bedside test kits (Actim partus kit) based on detection of
phosphorylated insulin-like growth factor binding protein-1(PIGFBP-1) in cervical secretions in predicting preterm delivery.
Material and methods: Patients presenting with symptoms of preterm labor between 28 and 36 weeks of gestation were
recruited. PIGFBP-1 bedside tests (Actim partus test) were performed. Managing obstetricians and patients were blinded to the
PIGFBP-1 results. Tocolysis and steroid therapy were administered to all the recruited patients. Outcome data were collected
after delivery. Results: Fifty patients were recruited into the study, the median [± standard deviation [SD] gestational age at
delivery was 34.12 weeks (± 2.1 weeks) and 37.14 weeks (± 2.8 weeks), patient testing positive and negative for Actim partus
test, respectively. A positive result was associated with significantly reduced admission-to-delivery interval. The median
admission-to-delivery interval was 3.25 days in the group with positive PIGFBP-1 results while 6.97 days with a PIGFBP-1
result (p < 0.001). Sensitivity, specificity, positive predictive value and negative predictive value of Actim partus test is 72.22%,
90.6% 81.25% and 85.29%, respectively. Conclusion: Actim partus (IGFBP-1) tests are effective adjuvant bedside test kits for
the prediction of preterm delivery in patients presenting with signs or symptoms of preterm labor. High negative predictive
values have great value in avoiding unnecessary interventions.
