my A1c moved and I cannot work out whether ice pack is why
Quick one. Canada here.
data logger works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.
Specifics: the route I used took 16 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.
Happy to answer questions from anyone in the same jurisdiction.
best — the order this archive was captured in
This is correct. Dry powder is way more robust than liquid.
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
Peak temperature and how long at that temperature?
lyophilised powder is far more forgiving than reconstituted solution
The gel pack lasted 13 hours in a courier van, then liquid. Powder itself fine, the cold chain mostly died in transit.
time-at-temperature integral is the dose, not just peak temperature
The gel pack lasted 13 hours in a courier van, then liquid.
Disagree on that part. 97.4% and 97.6% on the same vial is normal.
lane reports need origin, destination, carrier, and actual transit days
This is correct. Dry powder is way more robust than liquid.
This is the "correlation is mechanism" thing again. You changed three variables at once.
Strongly agree. Peak temperature is not the whole story.
Strongly agree.
Adding to this: stability is doing more work than the comment implies.
Strongly agree.
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
customs clearance often breaks the cold chain, factor that in
The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.
Customs clearance took 7 days. Package sat unrefrigerated during that. Powder tested clean after, reconstituted solution probably would not have.
data logger is the standard, gut feeling is not
France to France: 6 days with WXT and 39 days with HJ. Same route, different carriers, variance is real.
a warm courier van is a bigger problem for a mixed vial than for dry powder
Denmark to Denmark takes 12 days on average, variance is 14 days
