Inflammation thyroid: Inflammation? What is meant by this? A normal person's TSH can vary within the normal range. There can be assay variation in addition to biologic variation. A serious illness or chronic inflammation can cause "euthyroid sick syndrome" where TSH and T4 decrease, and then increase on recovery from the illness. During recovery, TSH can be above the normal range.
