Covid 19

While there is no specific test to determine whether someone has long COVID, a new study published in the journal Nature used blood tests to find new information about markers The biological signals associated with this series of mysterious conditions are reported by millions of Americans. Researchers used machine learning to help analyze immune markers and hormone levels in 273 adult participants from Mount Sinai University and Yale, and compared those with and without COVID symptoms lasting at least a year after contracting COVID-19.

Researchers used machine learning to help analyze immune markers and hormone levels in 273 adult participants from Mount Sinai University and Yale, and compared those with and without COVID symptoms lasting at least a year after contracting COVID-19.

Long Covid, defined in this study as symptoms lasting more than 6 weeks after infection, is associated with lower levels of a hormone called cortisol and with marked differences in certain immune cells. Fluid and signs of inflammation circulate in the blood.

These levels are determined through a blood test,

but this is not a blood test to specifically check for long Covid infection.

I think one of the most important findings of the paper is that it validates the symptoms that people have by finding biological differences between them and healthy controls,” Morris said. ”. said Dr. Shari Barnett Brosnahan, M.D., M.Sc., a COVID-19 researcher who was not involved in the study and is an assistant professor in the Department of Pulmonary, Critical Care and Sleep Medicine.

: “This is a truly remarkable study.” medicine in New York. York University Langone Health System, told ABC News. Brosnahan noted that "this is a limited analysis that they've done and I think there's still more work to be done." This study was conducted on relatively few people. Therefore, the researchers say that more research is needed to better understand the significance of these results in general. However, they say the study brings scientists one step closer to learning more about long Covid.

If there are specific biomarkers for long COVID, this could help confirm diagnosis or target treatment. oc;lc hxkks jmksx j jsc dmk ck dj jc ck c jcb k cm nc cmj kj cj jc cn nn cjcjjjjjjjjjjjjj nhc hnhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
