A freaky (but unimportant) blood smear finding
Have you ever seen one of these in a blood smear?
Looks freaky doesn't it?
This is a hemoglobin crystal, and it's actually not important at all! This is just an artifact where the hemoglobin crystalizes inside the RBC and forms this weird elongated (or sometimes brick-like) shape.
So, next time you see it, you can go ahead and tell it how cute it is and then move on with the rest of your blood smear review. 😎
