La Ricerca in Clinica E in Laboratorio
|October 1, 1976
Summary
This study presents a simple, reliable, and affordable radioimmunoassay for alpha-fetoprotein (AFP) using polyethylene-glycol (PEG). The assay is suitable for screening fetal abnormalities and other clinical applications.
Area of Science:
- Biochemistry
- Immunology
- Clinical Chemistry
Background:
- Alpha-fetoprotein (AFP) is a crucial biomarker in prenatal diagnostics.
- Accurate and accessible AFP measurement is vital for identifying fetal abnormalities.
Purpose of the Study:
- To describe a novel, simple, reliable, and inexpensive radioimmunoassay for AFP.
- To validate the assay's performance using clinical samples.
Main Methods:
- Development of a radioimmunoassay utilizing polyethylene-glycol (PEG) as a precipitating agent for antibody-bound AFP.
- Measurement of AFP concentrations in amniotic fluid, newborn sera, and maternal sera.
Main Results:
- The developed radioimmunoassay is simple, reliable, and inexpensive.
- AFP concentrations obtained from amniotic fluid, newborn, and maternal sera align with previously reported values.
- The assay demonstrates efficacy for screening purposes.
Conclusions:
- The described alpha-fetoprotein radioimmunoassay is a practical and effective tool.
- This assay meets the criteria for screening fetal abnormalities and supports other clinical applications.
