In brief: Blood test, nuc scan

Blood tests for thyroglobulin(tg) are very sensitive for persistent thyroid cancer.
Tg is only found in active thyroid cells, and after surgery and rai ablation, there should not be any cells or tg left. Blood tests for tg can show if thyroid cancer is still present, and nuclear scans with a diagnostic or therapeutic dose of radioactive iodine can show where thyroid cancer is still present.

If your entire thyroid was removed, there is a blood test, called the thyroglobulin level, that should be checked as well.
