Alpha-fetoprotein: a marker for threatened abortion
Summary
Alpha-fetoprotein (AFP) levels can indicate pregnancy complications. While serum human chorionic gonadotropin (HCG) is the best marker for threatened abortion, abnormal AFP levels, both high and low, signal a higher risk.
Area of Science:
- Obstetrics and Gynecology
- Reproductive Medicine
- Clinical Biochemistry
Background:
- Threatened abortion is a common obstetric complication.
- Accurate early prediction of pregnancy outcomes is crucial for timely intervention.
- Biochemical markers play a significant role in assessing pregnancy viability.
Purpose of the Study:
- To evaluate alpha-fetoprotein (AFP) as a marker for threatened abortion.
- To compare the efficacy of AFP with serum human chorionic somatomammotropin (HCS) and human chorionic gonadotropin (HCG).
- To determine the diagnostic utility of AFP in predicting adverse pregnancy outcomes.
Main Methods:
- Prospective study involving 50 patients with threatened abortion.
- Measurement of serum AFP, HCS, and HCG levels.
- Correlation of marker levels with pregnancy outcomes (abortion vs. live birth).
Main Results:
- Serum HCG was identified as the most reliable indicator of threatened abortion.
- AFP and HCS showed comparable efficacy but were less reliable than HCG.
- Abnormal AFP levels (both high and low) were significantly associated with early abortion (within 7 days).
- Normal AFP levels were observed in most cases of later abortion (after 7 days).
Conclusions:
- Serum HCG is the superior marker for threatened abortion.
- AFP offers valuable diagnostic information, as both elevated and decreased levels indicate an unfavorable pregnancy course.
- AFP's ability to detect both high and low deviations enhances its clinical utility in managing threatened abortions.
