Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Study population: 1. Pregnant and postpartum women 2. Newborn

Who may be able to join

  • Gestational Age: Singleton pregnant women with gestational age ≥ 20 weeks.
  • Clinical High-Risk Factors (meeting at least one of the following criteria):
  • Traumatic Factors: Abdominal trauma (e.g., traffic accident, fall), intrauterine fetal version, amniocentesis, chorionic villus sampling (CVS).
  • Obstetric Complications: Placental abruption, placenta previa, preeclampsia, unexplained antenatal hemorrhage, post-interventional therapy for twin-twin transfusion syndrome (TTTS).
  • Fetal Abnormalities: Fetal growth restriction (FGR), unexplained abnormal fetal heart rate monitoring, fetal hydrops, fetal anemia (elevated middle cerebral artery peak systolic velocity (MCA-PSV) detected by Doppler ultrasound).
  • High-Risk Population with Maternal-Fetal Blood Group Incompatibility: Maternal-fetal ABO or Rh-negative blood group incompatibility; positive result of the first-trimester antenatal antibody screening in pregnant women.

Who cannot join

  • Pregnant women complicated with severe hematological diseases (e.g., coagulation disorders, immune thrombocytopenic purpura) or autoimmune diseases.
  • Newborns who withdrew treatment for non-study-related reasons or were lost to follow-up after birth, resulting in missing outcome data.
  • Termination of pregnancy due to various causes.
  • Failure to complete the analysis due to unqualified core clinical data (e.g., quantitative hemorrhage test results, bilirubin levels) or unsatisfactory specimens (hemolysis, insufficient volume).

About this study

This study adopted a single-center, prospective, observational study design. A consecutive cohort of pregnant and postpartum women who met the inclusion criteria was recruited from Shanghai First People's Hospital between January 2026 and December 2028. Quantitative hemorrhage detection was performed using residual clinical blood samples, and the diagnostic value of this detection for hemolytic disease of the newborn (HDN) was analyzed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Hemolytic Disease of the Newborn(HDN)

    All the following criteria must have been met for a diagnosis of HDN: (1) Blood group incompatibility between the mother and newborn; (2) hyperbilirubinemia with a positive direct antiglobulin test (DAT) result or hyperbilirubinemia with a negative DAT result and a positive elution testing result with high suspicion of a hemolytic condition such as anemia and/or reticulocytosis.

    Measured: within 72 hours after birth

Secondary outcomes (2)
  1. Anemia: hemoglobin

    Hemoglobin Concentration in Peripheral Blood of Neonates

    Measured: within 72 hours after birth

  2. Incidence of severe hyperbilirubinemia

    The peak concentration of serum bilirubin is more than the exchange criteria of same gestational age and day age group

    Measured: 30 days
