Should Testing for hot or cold nodules be done?

[Psalms139]

I have a Thyroid Ultrasound because a Multinodular Goiter was seen on a CT Scan.  The Ultrasound shows a diffusely enlarged and Heterogeneous Gland.
Right Lobe:  Measures 4.7x1.6x1.1cm. with a 5mm cyst and 6mm hypoechoic nodule.
Left Lobe:  Measures 4.6x2.2x.1.7cm with a 3mm. cyst at the upper pole with multiple small hypoechoic nodules ranging in size from 4 to 11 mm. as well as a 4mm. complex cyst.

The TSH and Thyroid Antibodies are reportedly normal.  

Thanks,  Psalms 139

What are TPO?TG antibodies?  

Psalms139

[898]

Multiple small lessions are common in Hashimoto's patients. [the gland looks like Swiss cheese].
Have your TPO/TG antibodies checked.
The above condition can be present even with normal blood levels.
