Using SPINA-Thyr Software for Patients on No Thyroid Treatment or on Levothyroxine (T4) Only

SPINA-Thyr is a free diagnostic application, developed by Dr. Johannes Dietrich.

The software application takes thyroid laboratory test values TSH, Free T4 and Free T3 and performs calculations that enable in-depth evaluation of thyroid function, pituitary function, and T4-T3 conversion for people who are on no thyroid therapy or T4-monotherapy (Levothyroxine only).

This is an excellent post written by Dr. Tania S. Smith explaining about SPINA-Thyr and how to use it. It also explains in one of the references how anyone can download it.

Here is the link:
