Study: Long Covid Detectable in Blood Test

There is good news for people struggling with Long COVID because a new study has revealed new clues into what may cause that condition. Well, a study published yesterday in nature looked at the blood of 273 people and found several notable differences between the blood of those with Long COVID. People with Long COVID were more likely to have low levels of cortisol. That's a hormone that helps people stay awake and alert. And that could help explain why people with long COVID report fatigue and exhaustion. Interestingly, the study didn't find any evidence suggesting Long COVID is an autoimmune condition while looked at a small group of people. The study's author think it could help guide future research into how to help Long COVID patients. I think the more we know about COVID, Hannah, certainly the better. I think you're so right. There are still so many questions we hear from people who may be suffering from long COVID. I think this study may be the most light we've seen shed on the topic. It's a relief to know it's not an autoimmune disease according to this study. And there are lower cortisol levels that hopefully doctors can manage. So this is good news. But to your point, I think there's a lot more studying that needs to be done, but a step in the right direction.
