Can HIV be detected by blood donation?

Normally when we donate blood, we have to test the blood. When testing at the blood station, if there are some infectious diseases, we cannot donate blood. This also includes testing for HIV. If HIV infection is found, the blood station will notify the blood donor to go to the hospital for another re-examination. Of course, as an AIDS patient, you cannot donate blood, and it is possible to detect whether you have the AIDS virus when donating blood.

Donating blood can detect AIDS.

The blood station tests a total of 7 items: blood type, hemoglobin, hepatitis B surface antigen, hepatitis C antibody, syphilis antibody, and AIDS antibody. HIV is one of the mandatory tests for blood donation. If HIV infection is detected after blood donation, the donor will generally be notified for re-examination.

People with AIDS cannot donate blood.

AIDS testing is generally done by drawing blood for HIV antibody testing, usually at a local epidemic prevention station or Centers for Disease Control and Prevention. The best time for testing is the 6th and 8th week after high-risk behavior, with a confirmation rate of over 99%. If the HIV test result is negative, it means you are not a carrier of the HIV virus. Many municipal-level disease control centers now adopt voluntary free inspections, with the costs subsidized by the government.

One concept that needs to be made clear is that if you suspect you are infected with AIDS, you must not rely on blood donation for testing, but should go to the CDC for examination, which is the authoritative place. Because unsafe blood can endanger the patient's life and health. People with high-risk behaviors should not donate blood, such as those with a history of intravenous drug addiction, those who have sex with men, or those who are at risk of blood-transmitted diseases (AIDS, hepatitis C, hepatitis B, syphilis, etc.).

What are the blood tests for blood donors?

1. Blood specific gravity screening, copper sulfate method: greater than 1.052 for men and greater than 1.050 for women.

2. Blood typing: ABO blood type must match positive and negative typing. Rh(D) typing should be performed in areas where conditions permit or in areas with a high Rh-negative rate.

3. Liver function test: Using alanine aminotransferase activity as an indicator, the value measured by the Reitman method should be less than 25 units. If this indicator is unqualified, you should not donate blood, but it does not mean that there must be problems with liver function.

4. Blood infectious disease examination: check hepatitis B virus surface antigen, hepatitis C virus antibody, HIV antibody, syphilis serology test, etc. Anyone who tests positive is not allowed to donate blood.
