In the binary logistic regression analysis, leukopenia [odds ratio (OR) 7.316, 95% confidence interval (CI) 2.319–23.080, p < 0.001], prealbumin < 150 mg/L (OR 4.199, 95% CI 1.461–12.071, p = 0.035), and hyperpyrexia (OR 4.643, 95% CI 1.426–15.117, p = 0.035) were independent risk predictors associated with re-positivity for SARS-CoV-2 RNA. Here, TTR is linked to Decreased total leukocyte count.
