Blood tests for blood donation include blood type determination, complete blood count, liver function tests, infectious disease screening, coagulation function tests, etc. If abnormal test results occur along with physical discomfort, prompt medical evaluation is recommended to establish a clear diagnosis. Determining the donor's ABO and Rh blood types ensures compatibility between donor and recipient, thereby preventing hemolytic reactions.

Common symptoms of mild anemia include pale complexion, dizziness, fatigue, palpitations, shortness of breath, difficulty concentrating, and loss of appetite. If one or more of these symptoms occur, it is recommended to seek medical attention promptly for a complete blood count (CBC) test to confirm the diagnosis. In anemia, the oxygen-carrying capacity of red blood cells in the blood decreases, leading to insufficient oxygen and blood supply to tissues such as the facial skin, lips, and nail beds, resulting in a pale, bloodless appearance.

Chronic myeloid leukemia (CML) can be clinically cured in some cases. Patients who meet the criteria have the chance of complete cure through hematopoietic stem cell transplantation. For those ineligible for transplantation, standardized targeted therapy can effectively control the disease long-term and maintain a normal quality of life. Daily care requires strict adherence to prescribed medication without擅自 adjusting dosages. Regular follow-up tests, including complete blood counts and bone marrow aspiration, are essential.

Chemotherapy-related bone-protecting injections are primarily used to prevent skeletal-related events, protect bone density, relieve bone pain, reduce fracture risk, and minimize complications from bone metastasis. If persistent bone pain or limited limb mobility occurs, seek medical attention promptly. Chemotherapy drugs may impair osteoblast function, leading to bone metabolic disorders; bone-protecting injections can inhibit osteoclast activity.

In general, leukocytosis, medically termed as elevated white blood cell count, refers to a condition in which the number of white blood cells in the peripheral blood exceeds the normal range. Upon detecting an abnormal white blood cell count, it is important to maintain a regular作息 (daily routine), avoid staying up late and excessive fatigue, so as to keep the immune system stable. In terms of diet, emphasis should be placed on light yet nutritious foods, with increased intake of protein- and vitamin-rich foods.

In general, adverse reactions that may occur after blood transfusion mainly include febrile reactions, allergic reactions, hemolytic reactions, circulatory overload, and transmission of infections. The occurrence of transfusion-related adverse reactions is associated with multiple factors; therefore, it is essential to strictly adhere to standardized transfusion procedures and strengthen monitoring during the transfusion process to ensure the safety and effectiveness of blood transfusion.

Lymphocytic leukemia, also known as lymphoblastic leukemia, commonly presents with early symptoms such as fever, fatigue, swollen lymph nodes, tendency to bleed, signs of anemia, and bone or joint pain. If any of these symptoms occur, prompt medical evaluation at the hematology department of a正规 hospital is necessary. Fever is usually low-grade or moderate, although some patients may develop high fever.

Blood analysis evaluates the function of the hematologic system and screens for diseases such as anemia, infection, and coagulation disorders by measuring indicators in the blood including red blood cells, white blood cells, platelets, and hemoglobin. It also aids in diagnosing conditions affecting systems such as cardiovascular, hepatic, and renal. If test results show significant abnormalities, or if symptoms such as dizziness, fatigue, fever, or bleeding are present, prompt medical evaluation and further testing are recommended.

Iron deficiency anemia requires supplementation with foods rich in heme iron, non-heme iron, vitamin C-rich foods that promote iron absorption, and foods containing folate and vitamin B12 that support blood formation. Iron supplements may be taken as directed by a physician when necessary. If anemia symptoms continue to worsen or severe discomfort such as dizziness or palpitations occurs, prompt medical attention is advised.

The four principles of blood transfusion are: transfusion of the same blood type, compatible cross-matching, component transfusion, and appropriate transfusion volume. Blood transfusion must strictly follow medical guidelines. If there is a need for transfusion or any related questions, professional healthcare providers should be consulted promptly. Transfusing blood that matches the recipient's blood type prevents hemolytic reactions caused by blood type incompatibility and is the most fundamental principle of blood transfusion.
