For example, MS-based assays for serum thyroglobulin measurement are resistant to interference by anti-thyroglobulin antibodies, circumventing the need for long-term follow-up of differentiated thyroid cancer via costly methods such as neck ultrasound, radioiodine diagnostic whole-body scans, or fluorodeoxyglucose-positron emission tomography imaging [39]. The gene discussed is TG; the disease is thyroid gland carcinoma.
