Blood test may find who will get long COVID, study shows

Is it true that certain persons are more likely than others to develop physical, neurological, or cognitive symptoms months after their coronavirus infections have cleared?
It is one of the numerous enigmas surrounding long Covid: who is more susceptible to getting it?

Now, a team of researchers reports that they have uncovered biological variables that may help predict whether a person may acquire long Covid after receiving a Covid diagnosis.

According to a new study, low levels of a specific antibody that may be detected via a blood test may be able to determine whether a person is more prone to have lengthy COVID.

Additionally, these four factors may increase your chances of having a long Covid, according to researchers:

The presence of coronavirus RNA in the blood early in the infection; the existence of specific autoantibodies that wrongly attack bodily tissues; Type 2 diabetes; and Epstein-Barr virus reactivation.

The study published in the journal Nature Communications discovered that persons who suffer long-lasting symptoms of the virus have lower levels of two immunoglobulins — IgM and IgG3 — early after infection.

Immunoglobulins are antibodies produced by the immune system to combat infection.

The researchers found that lower antibody levels were around 75% effective at predicting whether a patient will develop long-term symptoms.

The study, which lasted from April 2020 to August 2021, monitored more than 500 patients during the infection phase and the subsequent year.

Researchers stated that additional research is necessary to confirm the findings, which could enable scientists in developing a test to predict who will experience long-term effects weeks, months, or even years after infection.

Since the onset of the pandemic, doctors and researchers worldwide have been attempting to figure out how to manage long-term COVID infection.

These protracted symptoms lack a clear classification, diagnosis, or therapy.

According to NBC News, approximately one-third of virus patients may experience symptoms for up to a month.
