Long COVID / Chronic COVID

People with Chronic COVID or long COVID, or “long-haulers,” are COVID-19 survivors but they have persistent symptoms such as shortness of breath, fatigue, headaches, palpitations, and impairments in mental health and cognition and in addition to many other symptoms. Chronic COVID is increasingly recognized as a public health crisis.

It’s estimated to affect as many as 30 percent of the millions who have suffered a COVID infection, even when the infection was considered to be mild. New research conducted by renowned pathologist Dr. Bruce Patterson and his team is helping to uncover the underlying immunologic causes of Chronic COVID.

Radiance Diagnostics has partnered with Dr. Patterson and his team at IncellDx and Chronic COVID treatment center and offer the following specialty testing to help recover from Chronic COVID condition.
