what would you tell week-1 you about A1c
what would you tell week-1 you about A1c. I am not trying to be the "source?" guy. I would just like a source.
Compared two draws across two labs and spent a week worrying before finding out the assays were different.
Took a baseline the week before starting purely because this board told me to. Best five minutes I have spent on this.
Draw at the same point in the week now, fasting, same lab. The noise dropped enormously once I standardised.
That is everything I have. The rest is opinion and I have tried to keep it out.
best — the order this archive was captured in
Different laboratories use different assay platforms with different calibration. Comparing across labs adds a systematic offset that is invisible on the report.
Different laboratories use different assay platforms with different calibration.
Agreed — and standardising the draw conditions is the cheapest improvement available.
ask whether the lab changed its assay between your two draws
Small fix — a reference interval is not a treatment target, and the post above uses them interchangeably.
baseline before you start is worth more than any later panel
I would not draw a line through two points, especially when the second was taken at a different time of day.

This is the sentence to read before anybody panics about a single value.
Brought the whole set to my clinician rather than one flagged value. Completely different conversation.
