Diseases detected by blood donation are usually communicated to the patients themselves, so that the donors can seek timely medical treatment to further clarify the diagnosis and receive timely and effective treatment. The blood donation test usually requires the completion of routine immunization, liver and kidney function, lipid analysis, blood routine, blood pressure and blood glucose measurement and other tests, through which the results of these tests may reveal syphilis, AIDS, viral hepatitis, anemia, liver function impairment, renal function impairment, hypertension, diabetes mellitus and other related diseases. Since the patient has the right to informed consent, the donor and his/her family should be informed when the above diseases are detected by blood donation. And the causes of some diseases are not yet completely clear, after informing the donor and his/her family, the donor needs to consult a doctor in time to clarify the specific disease and receive targeted treatment in time.
