It's mostly normal results, with a considerable amount of protein and calcium. And for its presence in the document itself, I believe it is meant to evoke a certain degree of plausibility. A blood analysis is something I'd do to this SCP, and I'm a medic by training. :O
Otherwise, while it is very similar to actual blood analysis doc, it's not necessary to the article… but it doesn't drag much.
Otherwise… I have to re-read it and give it a time. Let it sink in. I'm not sure about it, it's certainly good, and much much better than the previous one, but iffy at some points.
