Utility of a sensitive bedside serum pregnancy test

Area of Science:

• Reproductive Endocrinology
• Clinical Diagnostics
• Biomarker Analysis

Background:

• Ectopic pregnancy diagnosis requires sensitive and specific methods for timely intervention.
• Human chorionic gonadotropin (hCG) is a key biomarker in early pregnancy assessment.
• Evaluating rapid diagnostic tests is crucial for improving clinical workflows.

Purpose of the Study:

• To compare the diagnostic performance of a rapid qualitative serum pregnancy test against a quantitative hCG assay.
• To assess the utility of the rapid test in identifying women with suspected ectopic pregnancy.

Main Methods:

• Comparative analysis of a rapid qualitative serum test and a standardized quantitative hCG assay.
• Performance metrics including sensitivity and specificity were calculated.
• Tests were evaluated using serum samples from women with suspected ectopic pregnancy.

Main Results:

• The rapid qualitative serum pregnancy test achieved 100% sensitivity at a threshold of 25 mIU/mL.
• The rapid test demonstrated 96% specificity in identifying suspected ectopic pregnancies.
• High concordance was observed between the rapid assay and the quantitative hCG standard.

Conclusions:

• The rapid qualitative serum pregnancy test is a highly sensitive and specific tool for evaluating suspected ectopic pregnancy.
• This rapid assay can be reliably used as a preliminary diagnostic tool in clinical settings.
• The test's performance supports its integration into early pregnancy assessment protocols.
