Summary
Lymphopenia, decreasing CD8+ T cells, was found in infected patients. Abnormally high respiratory rates are also seen in patients with severe COVID-19.Elevated heart rate is similarly a key sign and may be a cause of dizziness or shortness of breath in patients with COVID-19 . Blood pressure is additionally a clinical sign for patients with COVID-19 . Hypoxemia is also a sign that indicates a below-average level of oxygen saturation in the blood. Mean corpuscular hemoglobin, lymphocytes, leukocytes, basophils, eosinophils, C-reactive protein, bilirubin, D-dimer are associated with COVID-19. Eosinophils regulate immune responses. Basophil level correlates with humoral response. CRP produced by hepatocytes, indicates cytokine storm. Aspartate transaminase indicates pulmonary fibrosis. Infected patients had lower calcium. High ferritin, severe lymphopenia, high CRP, D-dimer, ALT, AST indicate cytokine storm. High bilirubin in severe cases. D-dimer 3-4 fold increase indicates poor prognosis. Prothrombin time and CRP are elevated in COVID-19 positive patients . CRP is produced in the liver in response to inflammation and is a sensitive marker of inflammation in the body. An elevated CRP level along with other symptoms may indicate an active or current COVID-19 infection. Prothrombin time measures how long it takes your blood to clot and can be extended in people with COVID-19 due to complications like blood clots or organ damage.

A two-step procedure was used for model selection and evaluation, including data splitting and hyper-parameter optimization. Randomization was controlled for repeatability. Best models were trained on a combined dataset for external validation.

In COVID-19 positive patients, most blood parameters were normal except for prothrombin activity and CRP, which were elevated. Blood test parameters in COVID-19 patients differed significantly from those with other viral and bacterial infections.

High neutrophil levels and low lymphocyte levels are indicators of immune activation and impaired immune cell functions in severe COVID-19 cases. Other symptoms such as high respiratory and heart rates, elevated blood pressure, and hypoxemia are also observed in severely affected patients.
