To answer Dr.PulmRoch's question specifically:
From a clinical standpoint, Inter-lab variability in is well-supported by the literature.
The short answer: follow the standard titration protocol and reassess at 4-6 weeks.
The longer answer involves pharmacokinetic considerations around steady-state concentrations, which I am happy to elaborate on if helpful.
Just wanted to say — for anyone reading this Inter-lab variabilit thread who is feeling discouraged: it gets better. The first month are the hardest. Hang in there. 💪
OP here — wow, did not expect this much response! Thank you all for the thoughtful replies on Inter-lab variability in.
To answer PedsEndoPhilly: 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. 🙏
