Viewing the blood test report is mainly to analyze the condition based on the elevated or lowered values in the test report. Blood tests widely used in clinical treatment include routine blood test, coagulation function, immunity routine, macrobiotics and so on. 1. Routine blood test should be based on the blood cell count to clarify whether there is anemia, acute inflammation, leukemia, chronic myeloproliferative neoplasms and other possible diseases, so as to further improve the relevant tests to clarify the specific diagnosis. 2. Elevated values of PT, APTT and INR in coagulation function suggest the possibility of bleeding; on the contrary, decreased values of PT, APTT and INR or significantly elevated D-dimer suggest the risk of thrombotic diseases. 3. Immunization routine can clarify whether there is hepatitis B, hepatitis C and other hepatitis virus infection, whether there is HIV, syphilis and other infections. 4. Large biochemical tests include liver function, kidney function, blood lipids, electrolytes, fasting blood sugar, etc., which can clarify liver function and kidney function damage, hyperlipidemia, electrolyte disorders, hyperglycemia and other diseases. It is recommended that patients who undergo blood tests should consult a specialist to interpret the report and analyze their conditions.
