Many specific indicators in the blood routine of New Coronavirus are some commonly used sensitive indicators, which are sensitive to many pathological changes in the body. Among them, white blood cell count, red blood cell count, hemoglobin and platelets have the most diagnostic reference value. Many patients have unknown etiology You can do routine blood tests to assist in diagnosis. In addition, the blood routine test is also a common indicator for observing the effect of treatment, taking or stopping medication, continuing or stopping treatment, and relapse or recovery of the disease.
NCOVID19 pneumonitis in the early stage of the majority of the total number of white blood cells decreased or normal, lymphocyte count decreased, mononuclear cells increased or normal. If the absolute value of lymphocytes is less than 0.8 × 109 / L, it is generally recommended to review the blood routine changes after 3 days. According to the latest study by Academician Zhong Nanshan, 82.1% of patients had lymphopenia and 36.2% of patients had thrombocytopenia. The percentage of leukopenia in the total patients was about 33.7%. In severe cases, leukopenia, lymphopenia and thrombocytopenia were obvious.
2. Blood biochemistry: liver enzymes, cardiac enzymes, lactate dehydrogenase, myoglobin, troponin
Blood biochemistry is to detect the content of various ions, sugars, lipids, proteins, various enzymes, hormones and various metabolites present in the blood, which can provide doctors with the basis for diagnosis and treatment, and can help clinical determination Condition, monitoring treatment effect.
Some patients with NCOVID19 pneumonia have increased liver enzymes, myocardial enzymes, lactate dehydrogenase, erythrocyte sedimentation rate, and myoglobin, and some critically ill patients have increased troponin.
3. Other testing items: C-reactive protein (CRP), procalcitonin (PCT), D-dimer, erythrocyte sedimentation rate, coagulation image, blood gas analysis, lactic acid, etc.
Infectious diseases are often clinically adopted various targeted test items for auxiliary diagnosis, to provide doctors with diagnosis and treatment basis.
The detection of CRP and PCT is of certain value in identifying whether there is a bacterial infection in the lungs. Most patients with NCOVID19 have elevated CRP and erythrocyte sedimentation rate, and D-dimer is significantly increased in severe patients. At the same time, coagulation dysfunction and microthrombosis of peripheral blood vessels appear. form. In addition, blood gas analysis helps to judge the oxygenation of critically ill patients, and combined with the increase of lactic acid can screen high-risk patients with oxygenation disorders
