ELI5: What happens to blood after it's been tested?

I had another blood draw today for my GD test and it made me curious- what happens to the blood after the lab tests it? How is it disposed?

Blood is treated like any other kind of biohazard in a medical setting. There are special waste containers to hold biologically hazardous wastes, and a common method of disposing of such waste is incineration. Traditionally hospitals will have one or more incinerators in their basement where such wastes can be rendered into safe ash, while smaller establishments may just hold the waste for collection by a centralized service that incinerates it on their behalf.
