Why can’t a single blood test show you all the information you need instead of having to take multiple tests for different markers?

I don’t quite understand – I’m assuming that the poster and all the replies explaining “why” are in the US? And it’s maybe a US specific problem where they can bill more money if they draw more times?
I lived in the UK, and I was seriously ill for a couple of days with what turned out (later) to be food poisoning. Part of the documentation provided to me later after I left hospital was a variety of metrics about various blood markers. There were about 25 markers on the sheet, and they only took my blood twice in the time I was in hospital.
So it’s definitely possible to test for multiple blood markers (examples in mine were things like cholesterol, various levels of different types of blood cells, calcium, glucose, sodium, potassium etc.)
