Understanding changes in the biochemistry of an individual who is ostensibly healthy, including when they may show no overt symptoms of infection with SARS-Cov2, remains a huge challenge. Similar questions apply to understanding who is likely to live (unaided or via intervention) and who will die from COVID-19 once diagnosed, and the answers are equally unknown. Since we do not presently have any knowledge (although we know that there are cardiovascular changes that should have easily measured metabolic consequences (Zheng YY, Ma YT, Zhang JY, Xie X: COVID-19 and the cardiovascular system. Nat Rev Cardiol 2020), the best approach is to measure everything and find out.This approach is known as 'untargeted metabolomics'. We are experts in it (Kell co-invented the term 'metabolome'), and have already discovered novel measures of cardiovascular stress. We now wish to apply these to cohorts of serum samples that are already being collected in Liverpool and which will be made available to us (after treatment to remove all proteins, including virus). We anticipate that we shall be able to find markers that could be very early predictors of COVID-19 infection and prognosis.

了解表面上健康的个体生物化学的变化，包括何时没有SARS-COV2出现明显的感染症状，这仍然是一个巨大的挑战。类似的问题也适用于了解谁可能居住（无助或通过干预），一旦被诊断出谁会死于Covid-19，答案同样未知。由于我们目前没有任何知识（尽管我们知道有一些心血管变化应该很容易测量代谢后果（Zheng YY，Ma YT，Zhang Jy，Xie X：Covid-19和心血管系统。NATRev Cardiol 2020） ，最好的方法是衡量一切。这种方法被称为“非靶向代谢组学”现在希望将它们应用于已经在利物浦收集的血清样品，并将其提供给我们（在处理所有蛋白质之后，包括病毒）。 COVID-19感染和预后的早期预测因素。
