Of the various sensitive assays for human chorionic gonadotropin, the radioreceptor assay is now the most practical and should be used for the early diagnosis of pregnancy (35 days or less after the last normal menstrual period). Serial measurement of this hormone by the beta subunit radioimmunoassay provides a valuable guide to the management of ...

Pregnancy tests based upon the measurement of human chorionic gonadotrophin (hCG) in plasma or urine seek to identify the presence of trophoblastic cells, whereas pelvic ultrasonography ...

The first patient, a 26-year-old woman, had breast tenderness, was tired and suffered from abdominal pain. A urine pregnancy test was negative, but blood human chorion gonadotropin (hCG) concentration was 455 U/l (reference value ...
