Plasma hormone assay in pregnancy.

Area of Science:

• Obstetrics and Gynecology
• Reproductive Endocrinology
• Maternal-Fetal Medicine

Background:

• Pathologic pregnancies pose risks to fetal wellbeing.
• Accurate assessment of fetal health is crucial for timely intervention.
• Existing methods for evaluating fetal wellbeing may have limitations in interpretation or accuracy.

Purpose of the Study:

• To evaluate the utility of various hormonal parameters in assessing fetal wellbeing during pathologic pregnancies.
• To introduce a novel endocrine index for simplified and reliable interpretation of fetal health data.
• To demonstrate the clinical applicability of this hormonal index in managing high-risk pregnancies.

Main Methods:

• Measurement of hormonal parameters including human placental lactogen (HPL), estriol (E3), and alpha-fetoprotein (alpha-FP).
• Expression of hormonal data using standard deviation (S.D.) to create a constant endocrine index.
• Application of the methodology to data from pregnancies with pathologic conditions.

Main Results:

• The endocrine index, derived from hormonal parameters expressed as S.D., remained constant throughout pregnancy.
• This standardized approach reduced data interpretation errors.
• The hormonal index proved effective in reliably diagnosing pathologic situations.

Conclusions:

• The proposed hormonal index offers a simplified and accurate method for evaluating fetal wellbeing in pathologic pregnancies.
• This approach enhances diagnostic reliability and clinical practicality.
• The standardization of hormonal parameter expression facilitates consistent interpretation throughout gestation.
