What is assay of hormone?

An assay of hormone is a laboratory test used to measure the concentration of specific hormones in biological samples, such as blood or urine. These assays can help diagnose hormonal disorders, monitor treatment effectiveness, and assess various physiological conditions. Common methods include immunoassays, which use antibodies to detect hormones, and mass spectrometry, which provides precise quantification. Accurate hormone measurement is crucial for understanding and managing endocrine health.
