FSH vs SHBG: Key Differences Explained
Compare FSH and SHBG to learn which marker is more relevant for health assessment.
Introduction
Follicle-Stimulating Hormone (FSH) and Sex Hormone Binding Globulin (SHBG) are both essential biomarkers often used in hormone and endocrine health assessments. Understanding their roles, how they differ, and when to test each one can help guide more accurate diagnoses and treatment plans. This comparison explores each biomarker’s core function, clinical relevance, and how they are used together.
What Is Follicle-Stimulating Hormone?
Follicle-Stimulating Hormone (FSH) is a key biomarker involved in hormonal regulation. It plays a critical role in various biological processes and is commonly tested to evaluate related health conditions.
What Is Sex Hormone Binding Globulin?
Sex Hormone Binding Globulin (SHBG) is a key biomarker involved in hormonal regulation. It plays a critical role in various biological processes and is commonly tested to evaluate related health conditions.
