Thyroid cancer biomarker assays may show inaccurate readings

Researchers at Michigan Technological University found that thyroid cancer detection assays may not accurately measure two major biomarkers. The proteins tend to clump together, making it difficult to detect the true levels of thyroglobulin and galectin-3. By adding a step to break up these clumps, the tests could be made more accurate.
