+1 to mike_mod. Especially the point about "I have cleaned up a few off-topic posts..." — I have seen the same in my own experience with Inter-lab variability in.

OP here — wow, did not expect this much response! Thank you all for the thoughtful replies on Inter-lab variability in.

To answer Dr.GastroMayo: I get my labs done through Quest every 3 months.

Quick update: my latest labs came back even better. Thanks again for the evidence-based discussion — this is exactly why I posted in a science-based community. 🙏
