Thyroid disease is an epidemic, and millions of people suffer for years without proper diagnosis. Dr. Kellman's use of a highly precise thyroid test has been central to changing that for his patients.
A TSH within the reference range is routinely read as proof of normal thyroid function. For many patients it is not — fatigue, weight change, cold intolerance, hair loss, dry skin, constipation, and cognitive fog persist while labs read as unremarkable.
This test is often unknown and underutilized by other physicians. Its absence is why so many patients cycle through years of appointments without an accurate answer.
Dr. Kellman is recognized for expertise in thyroid disease and for the depth of testing he brings to it, detecting low thyroid function more definitively than conventional screening allows.
Because thyroid function is regulated in concert with the gut and immune system, treatment addresses the microbiome and inflammation alongside hormone status rather than treating the gland in isolation.
Yes, and it is one of the most common presentations at the Raphael Kellman, MD. Standard screening can read as normal while thyroid function at the tissue level is impaired. More precise testing frequently identifies what the standard panel does not.
Thyroid hormone conversion and immune regulation both depend on gut function. Microbiome disruption can impair conversion and drive the autoimmune activity behind conditions like Hashimoto's, which is why Dr. Kellman assesses both together.
