the baseline labs thing finally clicked for me and I want to write it down
Long-ish post, sorry. tl;dr at the bottom. I have been tracking bloodwork against eGFR for 39 weeks because I could not find anyone who had. The correlation is weaker than I expected, which is itself mildly interesting given how confidently people link the two in here. Caveats up front: one person, one lab, one…
Ferritin tanked from 13 to 35. Small appetite, reduced iron intake, nobody was testing it until I asked.
Strongly agree. ALT is where you catch the liver story early.
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
A1c moves slowly, quarterly is plenty
This is the "correlation is mechanism" thing again. You changed three variables at once.
HOMA-IR is crude but free and useful for tracking
This is correct. ApoB is the better marker.
post reference ranges with your numbers, units differ by country and lab
Not convinced. The evidence does not support that reading.
