quick context i left out of the post to keep it short:

last year i donated blood 3 times, after the 3rd one my ferritin dropped so low to anemic levels... not dangerous but low enough that i actually wanted to watch it recover instead of just hoping it would. problem was my results were scattered everywhere - one clinic portal, a pdf from another. different labs, different units, couldnt line any of it up. after building initial system i was also curious to include all my lab reports from years ago to have even more medical context in one place.

ferritin's back to normal now, slow climb but it worked, history documented :)

happy to answer anything if curious, please also share your experience about tracking biomarkers
