Rapid Differential Diagnosis of Graves' Disease and Painless Thyroiditis Using Total T3/T4 Ratio, TSH, and Total Alkaline Phosphatase Activity

When thyrotoxic patients are first seen in an outpatient clinic, it is important to make a differential diagnosis of Graves' disease (GD) and painless thyroiditis (PT). Using the three parameters of total T3/T4 ratio, TSH and T-ALP activity, all of which can be obtained within one hour in our h...

Zusammenfassung:When thyrotoxic patients are first seen in an outpatient clinic, it is important to make a differential diagnosis of Graves' disease (GD) and painless thyroiditis (PT). Using the three parameters of total T3/T4 ratio, TSH and T-ALP activity, all of which can be obtained within one hour in our hospital, 173 untreated patients with thyrotoxicosis were evaluated for the ratio of each parameter. For GD vs. PT, total T3/T4 (ng/μg) ratio (>20), TSH (
