Blood test can mainly detect hematologic diseases, infectious diseases, rheumatic diseases and some chronic diseases.
Blood test, i.e. routine blood test, can detect various kinds of acute and chronic leukemia, anemia, thrombocytopenia and other diseases, and according to the specific data, it can also analyze the cause of the disease, which is a routine test for the diagnosis of hematologic diseases, and if abnormalities are detected, further bone marrow examination is usually required. In addition, blood tests are often used to diagnose infectious diseases, as white blood cell counts increase rapidly in infected states.
Rheumatic diseases usually have changes in white blood cells and platelets, and some chronic diseases cause abnormalities in hematopoiesis, leading to chronic anemia.
Overall, blood tests are used in a wide range of clinical settings and often assist in the diagnosis of many diseases.
