What are the symptoms with COVID-19

Most people with COVID-19 recover within weeks of becoming infected, however, some individuals may develop post-COVID conditions. These are a wide range of new, returning, or ongoing health problems experienced more than four weeks after first being infected with SARS-CoV-2.

Post-COVID conditions may also be known as long COVID, long-haul COVID, post-acute COVID-19, long-term effects of COVID, or chronic COVID. The term “long hauler” is commonly used to describe patients suffering from the effects of long COVID. The CDC and experts around the world are working to learn more about short- and long-term health effects associated with COVID-19, who gets them, and why.

Clinical Lab Products (CLP) magazine published an article discussing the role of laboratory diagnostics post-COVID. It explains long COVID does not appear to correlate with the severity of illness, and the condition can affect multiple organ systems. Patients report a wide range of symptoms. Because the range of symptoms is so variable, it can be difficult to diagnose long-haulers.

“Just as laboratory testing was critical in helping to accurately diagnose acute COVID, lab testing is likely to play an ever increasingly important role in objectively diagnosing, characterizing, and identifying the cause of chronic COVID, as well as providing a path toward a more precision medicine approach to treatment,” the article said.

Clinical lab testing for chronic COVID includes a range of assays, as well as an approach that identifies and characterizes immunological abnormalities. Identifying which biomarkers are out of normal range can provide guidance as to which drugs may be useful for effective treatment.

To run diagnostic tests, clinical laboratories must store temperature-sensitive patient specimens and reagents. To ensure accurate test results (and reduce the risk of financial loss due to temperature excursions), it is important to use refrigeration designed for this purpose. Laboratories may want to know more about what makes certain cold storage units suitable for storing samples and reagents, and how these units can help ensure the lab is meeting the requirements of accrediting agencies.
