Long Covid: doctors find ‘antibody signature’ for patients most at risk

Doctors have discovered an antibody signature that can help identify patients most at risk of developing long Covid, a condition where symptoms can persist for many months.

Low levels of certain antibodies were found to be more common in patients who had long Covid than in patients who had a quick recovery.

In England, there are nearly 2 million days lost to staff absences.

When combined with the patient's age, details of their Covid symptoms and whether or not they had asthma, the antibody signature allowed doctors to predict whether people had a moderate, high or very high risk of developing long-term illness.

We think that our findings and identification of an immunoglobulin signature will help early identification of patients that are at increased risk of developing long Covid, which in turn will facilitate research, understanding and ultimately targeted treatments for long Covid.

175 people who tested positive for Covid were studied by the team. Doctors followed 134 Covid patients for up to a year to see how their symptoms changed after they were 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217

When Covid strikes, IgM and IgG antibodies rise in strength. The participants who had long Covid were found to have low levels of IgM and the antibody IgG3.
