Thyroid Nodule Blood Test Shows High Accuracy for Detecting Differentiated Thyroid Cancer
A new thyroid nodule blood test using serum thyroid-hormone metabolites showed 92.1% sensitivity and 99.7% specificity for differentiated thyroid cancer. The study may offer future diagnostic support for patients with indeterminate Bethesda III–IV nodules, although ultrasound, fine-needle aspiration biopsy and specialist evaluation remain essential.
