Question 1

What is the Meaning of Free Hormone Measurement?

Accepted Answer

Free Hormone Measurement is a specialized laboratory technique that quantifies the concentration of biologically active, unbound hormone molecules circulating in the bloodstream or saliva, as opposed to the total hormone concentration. Only the free fraction is capable of diffusing into target tissues and binding to cellular receptors to exert its physiological effect. This measurement provides a more accurate assessment of an individual's true hormonal status and tissue exposure than total hormone levels, which include the large, inactive fraction bound to carrier proteins like Sex Hormone Binding Globulin (SHBG). It is essential for precision dosing in hormone replacement therapy.

Question 2

What is the Origin of Free Hormone Measurement?

Accepted Answer

This measurement technique arose from advancements in clinical chemistry and endocrinology, recognizing that total hormone levels can be misleading due to variations in carrier protein concentrations, such as those caused by liver function or thyroid status. The term 'free' directly refers to the unbound, active fraction. The development of equilibrium dialysis and tandem mass spectrometry has allowed for increasingly accurate and reliable measurement of these minute, yet critical, concentrations. This represents a significant refinement in diagnostic hormonal assessment.

Question 3

What is the Mechanism of Free Hormone Measurement?

Accepted Answer

Hormones like testosterone and estradiol circulate predominantly bound to proteins, which acts as a reservoir and transport system. The small percentage that remains unbound is the fraction that freely traverses cell membranes to interact with intracellular receptors. Free Hormone Measurement isolates this active fraction, often using methods that physically separate the bound and unbound molecules before quantification. Clinically, a low free hormone level, even with a normal total level, indicates a state of functional deficiency because the target tissues are not receiving adequate hormonal signaling.
