No. You must conduct other thyroid tests to confirm the possibility of thyroid disease and then diagnose the patient’s specific thyroid problem. The chart helps determine whether your patient’s thyroid hormone levels and antibodies are in the normal/optimal range. Thyroid test results charts are crucial for interpreting these tests.

It’s likely due to differences in the populations they’ve studied, especially the locations of those populations. Each lab might also have different testing methods, including using different units like miu/l or mu/l for TSH levels. This is why we made our template editable so you can input your lab's normal/optimal reference ranges.
