Oof, you don't go down to zero platelets without something gone seriously off the rails.
Seems like it got caught right in time, but wishing for the best in the follow-up.
This being said, a problem with blood tests is that a layperson won't know right off the bat if a value outside of the normal range is ok or a life-threatening issue.
I understand it might introduce a lot of complexity for labs and that there's some level of "big picture analysis" involved that will require some human intervention, but even just a color-coded line for WBC/RBC, hemoglobin and platelets could already go a long way, as OP's case demonstrates.
It's complete enough, yes. I played it up until the "main quest" was done (building a TC machine).
It took approx. 20 hours and I loved it in a very similar way as the blog post author describes Nand2Tetris, so I'll have to look this one up too.
I was cleaning up some stuff on an old but still pretty important prod server and not paying enough attention on that day.
Turns out in retrospect that accidentally deleting ~/.ssh/authorized_keys on the main user account was not a good idea.
As the panic was starting to sink in, I managed to find out that an unprivileged user account was still available for SSH login.
Once I got a hold of it, I then tried my hand at running several privilege escalation exploits... until one of them worked (what a relief) and I could finally restore proper SSH access on the main user account.
It was both a proud and a pretty embarrassing moment.
For comparison purposes, tuition fees in a French public engineering school were around 700€/$800 per year when I was there about a decade ago, and I wouldn't expect this to have changed much.
Or if you're on Linux (Debian/Ubuntu), switch to one of the default virtual terminals with Ctrl-Alt-F1 (and Ctrl-Alt-F7 to switch back to your X server console on my machine) to experience the delight of low latency keyboard-to-screen typing.
