Postgraduate Medicine, 1978
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 ...

Early pregnancy is a vague term that is often used to describe the period between the presumed time of implantation and the end of the 6th week from the last menses. 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 ...

[Pregnancy tests: urine versus blood pregnancy tests].
Nederlands tijdschrift voor geneeskunde, 2014In this article, we discuss possible explanations for the discrepancy in results between urine and blood pregnancy tests. 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 ...

The most reliable pregnancy tests have long depended on the detection of chorionic gonadotrophin in urine. For many years these tests could only be carried out by costly and time-consuming biological methods, but now much more convenient immunological methods are available. This article discusses their use.
