Context: Recently, new methodologies have been applied to commercial
immunofluorometric (IFMA) and immunochemiluminometric (ICMA) LH and FSH assays …

Objective: We sought to establish normative data for spontaneous and gonadotropin-
releasing hormone (GnRH)-stimulated serum luteinizing hormone (LH) and follicle …

Objective: We assessed the utility of spontaneous and gonadotropin-releasing hormone
(GnRH)-stimulated serum luteinizing hormone (LH) and follicle-stimulating hormone (FSH) …

To establish normative data and determine the value of fluorometric AutoDELFIA assays
(Wallac Oy) in the investigation of precocious puberty, we determined serum levels of LH …

A sensitive and specific double antibody radioimmunoassay has been developed capable of
measuring gonadotropin releasing hormone (GnRH) in unextracted human plasma …

The increases in serum immunoreactive (RIA) LH and FSH concentrations during puberty
are small and of limited value in the evaluation of pubertal development. We, therefore, used …

Determinations of serum gonadotropin concentrations by ultra-sensitive methods have
improved the diagnosis of pubertal disorders. The onset of puberty can be estimated by …

It has recently been reported that measurements of bioassayable (B-) serum LH may be
superior to those of immunoassayable (I-) LH in the detection of normal and precocious …

Summary BACKGROUND AND OBJECTIVE The gonadotrophin‐releasing hormone
(GnRH) test is Important for the evaluation of children with disorders of puberty. Traditionally …

Serum bioactive and immunoreactive LH and FSH were measured in clinical conditions with
increased or decreased gonadotropin secretion. Gonadotropin immunoreactivity was …
