Introduction
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.

Blood tests for blood donation include blood type testing, complete blood count (CBC), liver function tests, infectious disease screening, coagulation function tests, and others. If abnormal test results occur along with physical discomfort, it is recommended to seek medical attention promptly for accurate diagnosis.

1. Blood Type Testing: Determines the donor's ABO and Rh blood types to ensure compatibility between donor and recipient, preventing hemolytic reactions. This is a fundamental test for safe blood transfusion and requires precise identification of blood group categories and antigen-antibody status.

2. Complete Blood Count (CBC): Measures indicators such as red blood cells, white blood cells, and platelets to evaluate the donor’s hematopoietic function and general health. It helps identify conditions like anemia or infection, ensuring that the donor is physically fit for donation and that the donated blood meets quality standards.

3. Liver Function Tests: Assesses levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, and other markers to reflect liver metabolism and functional status. This helps detect liver diseases such as hepatitis, ensuring blood safety and protecting the donor’s own health.

4. Infectious Disease Screening: Tests for pathogen markers including hepatitis B virus, hepatitis C virus, human immunodeficiency virus (HIV), and Treponema pallidum (syphilis). This strict screening prevents transmission of infectious diseases through blood transfusion and is crucial for recipient safety.

5. Coagulation Function Tests: Evaluates prothrombin time (PT), activated partial thromboplastin time (aPTT), and other indicators to assess blood clotting ability. This helps prevent prolonged bleeding after donation due to coagulation disorders and ensures normal coagulation function of the blood when used clinically.

Maintaining regular作息, a balanced diet, avoiding excessive fatigue and alcohol consumption helps keep blood parameters stable. After donation, donors should appropriately increase fluid and nutritional intake, avoid strenuous exercise, and keep the puncture site clean and dry to promote rapid recovery.

Is a blood test sufficient for checking liver and kidney function?
Under normal circumstances, liver and kidney function tests are not limited to blood tests alone; there are other methods of examination as well. Liver function assessment involves more than just blood testing. While blood tests are indeed an important means of evaluating liver function—measuring indicators such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, and albumin—to reflect liver function, liver function evaluation may also include physical examinations and other diagnostic methods.

What diseases can be detected through blood tests?
In general, blood tests refer to routine blood examinations. A complete blood count can detect conditions such as anemia, hyperlipidemia, diabetes, myocardial infarction, and leukemia. It is advisable to quit smoking and limit alcohol consumption to reduce the negative impact of unhealthy lifestyle habits on the body. Additionally, maintaining a positive mindset and avoiding significant emotional fluctuations is recommended to support overall health.

Can donating blood detect HIV/AIDS?
In general, blood donation can detect HIV. The blood testing process during donation includes specific screening for HIV. After donation, the collected blood undergoes rigorous testing at the blood center, including tests for human immunodeficiency virus (HIV) antibodies, antigens, and nucleic acid testing (NAT). In daily life, correctly and consistently using high-quality condoms during sexual activity is also an effective preventive measure.

Can norovirus be detected through blood tests?
Norovirus infection is primarily diagnosed through stool or vomit testing. Blood tests cannot directly determine whether a person is infected with norovirus; they can only indicate whether inflammation exists in the blood. Therefore, norovirus infection cannot be detected through blood testing. If infection is suspected, timely medical consultation for professional examination and targeted treatment is necessary. Additionally, attention should be paid to food hygiene and personal hygiene to reduce the risk of infection.

Can a blood test detect the flu?
Blood test refers to blood examination, and flu refers to influenza. In general, blood tests can detect influenza. If necessary, the test should be conducted under a doctor's guidance. After the human body is infected with the influenza virus, the immune system will quickly respond by producing specific antibodies against the influenza virus. Through blood testing, the presence and level changes of these antibodies can be detected.

How soon after successful implantation can pregnancy be detected?
Under normal circumstances, the time required to detect pregnancy after successful implantation depends on the testing method. Common detection methods include blood testing, urine testing, and ultrasound testing. If using blood testing, it usually takes 7-10 days to detect pregnancy; with urine testing, it may take 10-14 days; and for ultrasound testing, detection may not be possible until approximately 3 weeks after successful implantation.

Can blood tests detect AIDS?
Whether blood tests can detect HIV depends on the timing of the test. Outside the window period, when antibody levels are sufficient, blood tests can usually provide an accurate diagnosis. However, during the window period, when the viral load is low and antibody levels in the blood are insufficient, false-negative results may occur, making an accurate diagnosis impossible. It is important to note that blood testing is only one method available, and other diagnostic methods can also be used in combination for diagnosis.

How many days after in vitro fertilization (IVF) embryo transfer can pregnancy be detected?
Under normal circumstances, pregnancy refers to gestation. Pregnancy can be detected 10 to 14 days after in vitro fertilization (IVF) embryo transfer. Blood testing is the most accurate method for confirming pregnancy, as it measures the level of human chorionic gonadotropin (hCG) in the blood to determine whether a pregnancy has occurred. Urine testing is relatively simple and convenient, but it is less sensitive compared to blood testing.
