[Question] New Zealand — has anyone got a straight answer on certificate of analysis
Long-ish post, sorry. tl;dr at the bottom. I have been tracking COA against eGFR for 33 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 assay, no…

Disagree on that part. 98.7% and 98.3% on the same vial is normal.
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
redact your own name, not the vendor's batch details
post the whole document, not the headline number
the counterion is part of the mass you paid for
Slight fix: the number was 97.6, not 97.4. Decimal point, but a fairly consequential one.
