What happens if you mix up your blood types.

 The thought of mixing up blood types during a transfusion is absolutely terrifying! Just thinking about the consequences is enough to give me goosebumps. The fact that such a simple mistake can lead to the destruction of red blood cells and the release of hemoglobin, which can then clog up our kidneys and lead to acute renal failure is absolutely horrifying. And if that's not bad enough, it can also lead to hemotransfusion shock, heart malfunction, pulmonary edema, and even death!

This is why it's so incredibly important for us to know our blood type and for medical professionals to take every precaution to make sure that they're using the right blood type during a transfusion. It's crazy to think that up until the middle of the 20th century, it was thought that the first blood group was universal and could be transfused to anyone without negative effects. It's only thanks to the hard work of scientists like Karl Landsteiner and Jan Jansky that we now know the true dangers of mixing up blood types.

So let's all take a moment to appreciate the importance of blood typing and transfusion safety. It may not be the most exciting topic, but it's one that could literally mean the difference between life and death.
