Too many of these patients have undergone invasive surgical procedures before clinicians are comfortable arriving at this diagnosis but enhanced technology finally may remove this diagnostic uncertainty. I ran AFIRMA and then another doc did a Quest Diagnostic Panel-- it tested about 7 genes, so not as comprehensive as the Thyroseq. Epub 2014 Mar 31. The activity level of 142 genes is measured within each nodule and then the nodule is classified as either benign (risk of cancer less than 6%) or suspicious for cancer. Both Afirma GEC and Thyroseq v2 performance have been affected by NIFTP reclassification. ThyroSeq v2 was essentially uninformative for nodules with a B-III diagnosis (Fig. CONCLUSIONS: For ThyroSeq molecular panel, while it did not appear that there was an increase in rate of high-risk mutations detected in the samples with Hurthle cell … The I 2 statistic for sensitivity and specificity was very low in both, Afirma-GEC and ThyroSeq v2.
