Severe COVID Patients Have Very Low Levels of This Immune Cell

This novel discovery may partially explain the severity of symptoms in some people.  In an early study out of Wuhan, China on patients that were hospitalized with COVID, severe cases tended to have very low levels of T-lymphocytes, which are specialized white blood cells that protect against infections.  This decrease of T-lymphocytes (also called T-cells) correlated with in-hospital death and severity of illness. Low T-cell count was also seen in patients with... Read More

Should COVID Vaccines Engage T-Cells?

  Leading immunology researchers suggest the answer is YES . In the case of existing COVID vaccines, immunity comes from B-cells, which are immune cells that produce antibodies.  But there is another arm to our immune system – the underrated T-cell – that that is too often overlooked in vaccine development, according to recent research.  Evidence suggests T-cell immunity may confer longer lasting protection and may explain why some people fare better when infected...

Do T-Cells Hold the Key to Long Lasting Immunity from COVID?

  In patients who have confirmed COVID infections, many don’t have detectable levels of antibodies in their blood, yet these same patients do have T-cells with receptor memory specific to the COVID virus.    T-cells may hold the key to long lasting immunity against this virus. As antibodies wane over time, research suggests T-cells confer longer lasting protection from COVID and its variants. Although antibody immunity has received the bulk of attention in... Read More

Serum vs Intracellular Nutritional Testing: The Difference Matters

  What is serum testing? A serum test is simply a laboratory test that detects something in the liquid (which would essentially be the plasma) part of blood, as opposed to a laboratory test that detects something in the solid part (which would be the red and white blood cells) of the blood. Since blood is made of both cells and plasma, the term “blood test” is not very specific, as it could refer to either. However, the term “serum test” is specific... Read More
