A 39-year-old female asked:

If you have hashimoto thyroiditis will it mess with the results of a fna or blood work?

No: We can spot both the hashimoto's and whatever else may be going on in the thyroid at the same time on the fna. Same for the labs. Hoping things turn out for you and glad you're taking a proactive approach to your health.

Unlikely: I am not sure what you mean by mess with the results, but hashimoto's is the most common cause for hypothyroidism in the us. It will not affect test results, other than thyroid levels (low thyroid). Fna can show some abnormalities, such as lymphocytes, hurthle cells, sometimes some atypia, but most of the time, one can tell malignancy when present.
