Screening method to evaluate point-of-care human chorionic gonadotropin (hCG) devices for susceptibility to the hook effect by hCG β core fragment: evaluation of 11 devices.

BACKGROUND The predominant hCG variant in urine, hCG β core fragment (hCGβcf), has been demonstrated to cause false-negative results in qualitative point-of-care (POC) hCG devices. This is a major concern for healthcare professionals using POC pregnancy tests. We developed a screening method to evaluate qualitative POC hCG devices for their susceptibility to inhibition by hCGβcf. Using this met...

Human chorionic gonadotropin (hCG) versus magnesium sulfate to arrest preterm

Introduction: Considering the high incidence of preterm labor and its known complications, and that human myometrium contains receptors for human chronic gonadotropin (hCG) and that hCG can inhibit myometrial contractions on vitro, made me study treating effects of hCG on preterm labor. This clinical trial study was carried out to compare the effect of hCG, and magnesium sulfate (mgso4) on pre...

Increased Human Chorionic Gonadotropin Due to Hypogonadism

nonsignificant differences between cutoffs for serum and plasma and between assays are encouraging regarding the ease of interpretation by clinicians and laboratories. Also encouraging were improvements in the analytical sensitivity of these newergeneration assays. Interestingly, only 3 samples were identified as above the 99th percentile by all 3 assays. The mechanisms responsible for this lac...

Human chorionic gonadotropin (HCG) induction of apoptosis in breast cancer.

10658 Background: Apoptotic induction in cancer cells may improve the efficacy of local or systemic therapy. Human Chorionic Gonadotropin (HCG) injection directly into Kaposi's sarcoma or melanoma has been shown to increase the apoptotic index in these tumor types. The rapid induction of apoptosis in breast cancer immediately preceding local or systemic therapy may improve the response to thera...
