If you don't give the blood test report, 100% you donated blood to the hospital. I just dare not make a fake medical examination and blood test report. This is the evidence.
If you have a blood test report, you can do a routine blood test in a regular doctor. A drop of nail blood costs tens of dollars, and then you can find the problem by comparing it.
There are more items in the blood test report than in the blood routine. If it's the same, hehe, a drop of blood was tested and the rest was donated to the hospital.
