In modern medicine, routine blood testing is widely used in the diagnosis, prognosis and evaluation of various diseases. It can help doctors diagnose diseases and develop ** protocols. Under normal circumstances, the cost of routine blood testing is about 20 yuan, and the results can be obtained in about half an hour.
The main indicators of a complete blood count include red blood cell count, white blood cell count, and platelet count, in addition to hemoglobin concentration. If these indicators are abnormally elevated, it may be a sign of certain diseases and need to be alarmed.
The most common causes of elevated red blood cell counts are hypoxia and polycythemia. When hypoxia, the body will compensate for the increase in the number of red blood cells in order to adapt to the hypoxic environment, thereby increasing the oxygen-carrying capacity of the blood.
This condition is common in highland residents, patients with lung diseases, etc. Polycythemia is a chronic myeloproliferative disorder with common symptoms such as dizziness, fatigue, and palpitations. If the red blood cell count is persistently elevated, further tests such as a bone marrow aspirate should be done to confirm the diagnosis.
Elevated white blood cell counts are common in infections and stress responses. Infectious diseases are the most common cause of elevated white blood cell counts, especially bacterial infections. In addition, stress reactions such as fever, surgery, and trauma can also cause an elevated white blood cell count.
If the white blood cell count is persistently elevated, and it is accompanied by fever, fatigue, cough, diarrhea and other symptoms, further chest x-ray, CT, urine, blood and other related tests should be further examined to confirm the diagnosis.
Elevated platelet counts are common in hematologic disorders such as thrombocythemia and myelodysplastic syndromes. Thrombocythemia is a myeloproliferative disorder, and common symptoms include purpura, nosebleeds, bleeding gums, etc. Myelodysplastic syndrome is a malignant clonal disease of hematopoietic stem cells, and common symptoms include anemia, bleeding, infection, etc.
If the platelet count is persistently elevated and accompanied by the above symptoms, further tests such as bone marrow aspirate should be performed to confirm the diagnosis.
In addition, certain physiological changes may also lead to an increase in blood routine indicators, such as erythrocytosis caused by mental factors, and thrombocytosis during menstruation in women. These cases usually require no special treatment and only need to be reviewed regularly.
