Generally speaking blood samples are retained for a period of time as dictated by the Laboratory's policy for blood sample retention. Some samples are kept only 24-48 hours and others are retained for 7 days. Sometimes the sample will be frozen for future testing, if a physician requests it. Once the sample is no longer good, the whole tube (usually cap'd) is disposed of in a large (3x3ft) biomedical waste bin. Hundreds of tubes of blood are put into the bin. The plastic bins which are lined with red plastic biohazardous waste bags (like thick red garbage bags) are picked up and taken by a Medical Waste treatment company to be incinerated (burned). The bins are then decontaminated and returned to the hospital to be used again. The Laboratory does not wash out tubes of blood nore pour them in sterilization liquids. This would create the possibily exposure situation to blood products, for laboratory workers, so contact with the samples after the testing is completed is minimized through this process.

Ve DRINK it! Muahahahaha!
Usually the blood is kept in a cold store (or freezer) depending on the type of sample.
It is not usually suitable for blood transfusions. The blood for testing is usually in special tubes with special additives which will prevent clotting or cause clotting, kill the metabolic activity of blood cells, etc.
Blood for blood transfusions is taken in a different manner (well, with a bigger needle and placed into special collection bags, weighed, tested, etc) and stored in a different way (in special preservatives).
In some cases blood drawn for blood tests can be kept for some years but in the case of most samples it is discarded after about 1-4 weeks (in case some research happy doc calls the lab and says "oh - can you get that old sample and run such and such a test!") the length of time depending on - size of hospital, size of lab, type of sample

After the retention period expires (for conducting additional testing/experimentation), leftover blood goes into biomedical waste containers and eventually is incinerated.

put it in the dust bin (a special one for organic waste)

They rinse the containers with water and down to a special drainage that is treated so it wouldn't spread out if there is a disease,,,,,,,,..........
