Assessing Thyroid Function: A Review of Biochemical Markers and Testing Strategies

Abstract

The present work provides an in depth look at the biochemical markers and the testing strategies employed in appraising thyroid function. It involves the primary thyroid hormones such as TSH, T3, and T4 that are responsible for thyroid homeostasis and diagnosis of the dysfunction of the thyroid. The assessment also covers and evaluates the different testing methods and approaches to examine thyroid function which include immunoassays and mass spectrometry. The review offers the summary of advantages and disadvantages of different testing methods to increase the knowledge and to facilitate decision making regarding the diagnosis of thyroid function, and to improve the quality of care of thyroid-related conditions.
