News Release Details

SAN DIEGO--(BUSINESS WIRE)--Jun. 7, 2017-- Quidel Corporation (NASDAQ: QDEL), a provider of rapid diagnostic testing solutions, cellular-based virology assays and molecular diagnostic systems, announced today it has received the CE Mark for Quidel’s Thyretain® TBI Reporter BioAssay for the qualitative detection of blocking autoantibodies to the thyroid-stimulating hormone receptors (TSHR) in serum.

According to the Centers for Disease Control and Prevention (CDC), autoimmune diseases are the third most common category of disease in the United States after cancer and heart disease. Autoimmune diseases affect roughly 14–22 million persons, and approximately 80% of the persons affected with autoimmune diseases are women.¹

One such autoimmune disease, autoimmune thyroiditis (AT) or Hashimoto’s disease, is a chronic inflammatory disorder of the thyroid gland that is caused by abnormal blood antibodies and white blood cells that mistakenly attack and damage healthy thyroid cells.² In autoimmune thyroiditis, thyroid-blocking immunoglobulin, or TBI, prevents or blocks the TSH from binding to its own receptor, TSHR. This event stops the intracellular signaling cascade required for the production and secretion of thyroid hormones. AT is characterized by a deficiency of thyroid hormone.

Autoimmune thyroiditis begins slowly. It may take months or even years for the condition to be detected and for thyroid hormone levels to become lower than normal.³ Possible signs and symptoms of hypothyroidism can include: memory loss, fatigue and sluggishness, increased sensitivity to cold, constipation, pale, dry skin, hair loss, enlargement of the tongue, unexplained weight gain, muscle aches, stiffness, and depression.⁴ Therefore, it is important to provide a diagnostic method to detect the thyroid blocking antibodies that can aid physicians in patient care.

Quidel’s Thyretain TBI Reporter BioAssay utilizes a patented bioassay technology to detect TBI in human serum. Until now, no specific TBI detecting method was available in the market. The assay enables highly complex laboratories to quickly diagnose autoimmune thyroiditis in just a few days.

“We’ve developed a test that can truly make a difference in the lives of those who are suffering from AT, a disease that can take years to diagnose,” said Douglas Bryant, president and chief executive officer of Quidel Corporation. “We are pleased to expand our Thyretain franchise, and to bring meaningful solutions to key issues that affect patients globally.”

The assay is currently available for sale in Europe, and not yet available for sale in the United States.
