Do you know whether you are a donor or a vampire?

The only way to know for certain whether you are a donor or a vampire is to have a blood test performed by a qualified medical professional. This test will measure the levels of iron, hemoglobin, and other components of your blood to determine whether it is compatible with the needs of a vampire or donor. If you have a higher than normal level of iron, hemoglobin, or other components, it is likely that you are a donor. If your levels are lower than normal, it is likely that you are a vampire. It is important to note that even if your blood tests indicate that you are a donor or a vampire, this does not necessarily mean that you are one or the other. Your lifestyle, diet, and other factors can also affect your blood composition, so it is important to speak to a qualified medical professional to determine the best course of action for you.
