| Summary: | Abstract Background Measuring thyroid hormone levels is essential and helpful in the diagnosis of thyroid diseases. Case presentation We had a patient with undetectable serum TSH level by the Siemens immunoassay, whereas by ELISA and Roche-Abott immunoassay, serum level of TSH was in the normal range. Conclusion If the result of TSH level revealed very low or undetectable through one specific method, it should not be considered necessarily as a symptom of hyperthyroidism. It is to be requested to measure by the other methods with other devices too. |
