Our objective was to evaluate some common blood parameters and use them for the differential diagnosis of childhood infections.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>This retrospective study was conducted between October 2019 and September 2020 at Guangzhou Women and Children\u2019s Medical Center, China. We performed blood tests in patients infected with DNA viruses (n = 402), RNA viruses (n = 602), gram-positive organisms (G+; n = 421), gram-negative organisms (G\u2212; n = 613), or <jats:italic>Mycoplasma pneumoniae<\/jats:italic> (n = 387), as well as in children without infection (n = 277). The diagnostic utility of blood parameters to diagnose various infections was evaluated by logistic regression analysis.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>The most common G+ organism, G\u2212 organism, and virus were <jats:italic>Streptococcus pneumoniae<\/jats:italic> (39.7%), <jats:italic>Salmonella typhimurium<\/jats:italic> (18.9%), and influenza A virus (40.2%), respectively.

The logistic regression\u2010based model showed significantly greater accuracy than the best single discriminatory marker for each group (logit [<jats:italic>P<\/jats:italic><jats:sub>infection<\/jats:sub>] vs. CRP, 0.90 vs. 0.84, respectively; logit [<jats:italic>P<\/jats:italic><jats:sub>RNA<\/jats:sub>] vs. lymphocytes, 0.83 vs. 0.77, respectively; p = 0.00). The area under curve values were 0.72 (0.70\u20130.74) for HGB and 0.81 (0.79\u20130.82) for logit (<jats:italic>P<\/jats:italic><jats:sub>virus\/bacteria<\/jats:sub>) to diagnose bacterial infections, whereas they were 0.72 (0.68\u20130.74) for eosinophils and 0.80 (0.78\u20130.82) for logit (<jats:italic>P<\/jats:italic><jats:sub>virus\/bacteria<\/jats:sub>) to diagnose viral infections.
