A similar pattern of expression was observed in our cohort, with elevated levels of SAA (p < 0.0001*), CRP (p < 0.0001*), and LBP (p < 0.0001*) alongside a decrease in ALB (p < 0.0001*) in all unhealthy individuals presenting ill at the hospital, regardless of COVID-19 status (Fig. 4). Here, ALB is linked to COVID-19.
