CBC is the most commonly ordered blood test in the world with more than 4 billion ordered globally each year. CBC is a strong indication of the overall health of a person and irregular levels can indicate a myriad of health issues including anemia, leukemia, and more. CBC results can help inform treatment decisions, including the amount of medication to give a patient.

CRP - About 7.7% (16/209) of nonsevere adult COVID-19 patients progressed to severe cases after admission. Compared with nonsevere patients, the aggravated patients had much higher levels of CRP (median [range], 43.8 [12.3–101.9] mg/L vs 12.1 [0.1–91.4] mg/L; P = .000). A regression analysis showed that CRP was significantly associated with aggravation of nonsevere COVID-19 patients, with an area under the curve of 0.844 (95% confidence interval, 0.761–0.926) and an optimal threshold value of 26.9 mg/L.

BLOOD SUGAR Diabetes is a risk factor for hospitalisation and mortality of the COVID-19 infection. Diabetes was a comorbidity in 22% of 32 non-survivors in a study of 52 intensive care patients.2 In another study of 173 patients with severe disease, 16.2% had diabetes, and in further study of 140 hospitalised patients, 12% had diabetes.3,4 When comparing intensive care and non-intensive care patients with COVID-19, there appears to be a twofold increase in the incidence of patients in intensive care having diabetes.11 Mortality seems to be about threefold higher in people with diabetes compared with the general mortality of COVID-19 in China.2–1

SaO2 Oxygen saturation is the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal arterial blood oxygen saturation levels in humans are 95–100 percent
