For hematological data, in comparison to wild-type infections, delta variant patients (unvaccinated) demonstrated alleviated leukocytosis, neutrophilia, levels of CRP, ALT, GGT, LDH, PCT, PTT, INR, and D-dimer, but deteriorated monocytosis, thrombocytopenia, levels of ALP, creatinine, CPK, thrombin time, and fibrinogen, showing a varying set of clinical characteristics. This evidence concerns the gene PIK3C2A and Thrombocytopenia.
