Blood test could predict people at risk of long COVID: Lancet study

London: A blood test could predict if a person infected with the SARS-CoV-2 virus will develop long COVID, a study published in the Lancet eBioMedicine journal suggests.

Some people who have been infected with COVID-19 experience long-term effects from their infection, known as long COVID.

The researchers at University College London (UCL) in the UK analysed proteins in the blood of health care workers infected with SARS-CoV-2, comparing them to samples from those who had not been infected.
