Blood draws are no fun.
They hurt. Veins can burst, or even roll like they re trying to avoid the needle, too.
Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19; or cytokines indicative of inflammation seen in conditions such as rheumatoid arthritis and sepsis. ....
