An Immunochemical Test for Chorionic Gonadotrophin.
نویسنده
چکیده
An immunochemical procedure for routine laboratory diagnosis of pregnancy utilizing adsorption of human chorionic gonadotrophin onto kaolin and the Ortho pregnancy test reagents is described. The method is suitable for quantitative assay of urinary human chorionic gonadotrophin and can be adapted for use with serum. It was found to compare favourably with the reliability of Galli-Mainini toad tests. It avoids the disadvantages of ;biological' tests and is quicker to perform.

Urinary chorionic gonadotrophin determination.
Successful laboratory tests for early pregnancy utilize the endogenous production and excretion of chorionic gonadotrophin (CG). There is wide variation in sensitivity and specificity of various biological and commercially available immunochemical methods for determining urinary CC levels. Normal values for immunochemically reactive CC during the first trimester of pregnancy are given. Serial d...

OBJECTIVE To determine the ability of a sensitive one step urine test to detect human chorionic gonadotrophin in women with suspected complications of early pregnancy. DESIGN Test on women presenting to accident and emergency department with gynaecological problems over six months. Results were validated using a quantitative assay for human chorionic gonadotrophin in serum and urine. SETTIN...
متن کاملHuman chorionic gonadotrophin as an indicator of persistent ges-tational trophoblastic neoplasia
Background : Gestational trophoblastic neoplasia (GTN) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. Many attempts have been made to improve follow-up procedures, but no studies have evaluated Human Chorionic Gonadotrophin (HCG) as a post treatment indicator. Thus we aimed to know β-HCG variability in post treatment pregnancies. Meth...

Background: The demand for producing recombinant therapeutic proteins by mammalian cell lines, such as Chinese hamster ovary (CHO) cells, continues to grow. Significant achievements in process optimization including development of cell culture strategies for largescale and cost-effective production have been made. Fetal bovine serum (FBS) is an often essential growth supplement and yet most cos...
متن کاملPredictive value of plasma human chorionic gonadotrophin beta subunit in diagnosing ectopic pregnancy after in vitro fertilisation and embryo transfer.
A study was conducted aimed at establishing a range of plasma concentrations of the beta subunit of human chorionic gonadotrophin that might predict ectopic pregnancy after in vitro fertilisation and embryo transfer. From May 1984 to February 1986, 161 consecutive pregnancies at the Monash University in vitro fertilisation unit were analysed by determining plasma beta human chorionic gonadotrop...
