In the case of novel coronavirus, the first step is to take a blood test to see if the white blood cells are elevated, normal, or decreased, and if the lymphocytes are increasing or decreasing. In the case of novel coronavirus, the common blood tests show that the total number of white blood cells is normal or even decreasing, and the number of lymphocytes is decreasing. Chest X-ray and lung CT can show hairy glass-like changes and blurred changes in both lungs. The current method for confirming the diagnosis of coronavirus is nucleic acid testing. In severe cases, other tests are done, such as cardiac enzymes or even cardiac ultrasound if there is a suspicion of combined damage to the heart muscle. If there is a suspected effect on the liver, liver function should be checked. If there is an effect on the hematological system, coagulation is checked. Once the patient’s lungs have been damaged, which may cause the respiratory system, resulting in reduced lung function, the patient’s blood gas should be checked to see if hypoxemia has occurred and if there are any ARDS manifestations. As for the related costs, there are already national regulations that all treatment costs for new coronavirus pneumonia are reimbursed by medical insurance, and the out-of-pocket expenses are also covered by the central and local finances.
