Abstract

This chapter focuses on some clinical applications of human chorionic gonadotropin (hCG) assays, especially to detect early pregnancy loss. The collection and storage of urine samples for assay is an easy and painless procedure, so urinary measurements of hCG, rather than serum measurements, have been utilized for most epidemiologic studies of human reproduction.
