what lab tests are performed after an amputation of a leg?

Why would someone be having a leg amputated?

Unless the patient has an infection or other health issue which needs to be monitored, there aren't any.

● "What lab tests are performed after an amputation of a leg?"

After my leg was amputated (below the knee) in June 2015, most or all of the testing was done on the spot - blood pressure, blood sugar level, pulse rate - and several times a day. Those DID vary enormously for several days, and there were nights when the nurses were worried enough to test one or more of them every 2 hours - which did NOT give me time to get enough sleep!

I don't actually remember ANY sample being taken away to be checked in the hospital's laboratory AFTER the surgery, but some of the blood samples drawn were probably after the surgery. My biggest concern was that they were running out of places to insert the needle of the IV drip feed which, I think, was an antibiotic plus saline. From wrist to elbow on both arms I had tender spots for some time!

Whether other testing was done after the calf muscle was attached to my shin bone, I don't know. The surgery began at about 🕛 midnight, and I woke at about breakfast 🕢 time but, because they'd needed to transfuse 2 litres/4¼ pints of blood into me (which is just under half of what an adult male contains), I wasn't allowed to return to the ward until lunch time, so had breakfast & morning coffee in the BORing observation room.
