Use

This assay is a send‑out immunoassay primarily reserved for pediatric patients with suspected or complex endocrine abnormalities. It measures follicle‑stimulating hormone (FSH) to assess gonadotropic activity in children; normative ranges vary by age and sex. The assay is not intended for adult use unless approved separately. It aids clinicians in evaluating pediatric endocrine function or potential disorders of puberty and gonadal axis function.
