Why do you need to take many small samples when taking a bloodtest? Why can’t they just take one and use small amounts from there?

I used to do IT work in a worldwide lab. In many cases its a second reference sample. In the case of a dire test result they will test with a second machine – in the case of a positive HIV test we would send the second tube to a independent lab for testing. Our system was highly automated and the machines would take a sample from the referenced tube to then further process. A single reference tube might be processed through several machines – each removing the desired amount to start processing.
