ALB and COVID-19: Regarding the mechanism of action of TCM, a retrospective analysis performed by An et al[94] found that TCM treatment led to a decrease in white blood cell count, serum interleukin-6, procalcitonin, and serum γ-glutamyl transpeptidase, while prealbumin, albumin, red blood cell, hemoglobin, and platelet count were increased in patients recovering from COVID-19 compared to not TCM treatment.
