[Discussion] can we stop arguing about eGFR until somebody posts a number
can we stop arguing about eGFR until somebody posts a number. If this has been answered properly somewhere, link me and I will delete.
Draw at the same point in the week now, fasting, same lab. The noise dropped enormously once I standardised.
Added ApoB to the panel after a thread here. It told me something the standard lipid panel had been hiding.
Compared two draws across two labs and spent a week worrying before finding out the assays were different.
Research-use-only material is not approved for human use and nothing here should be read as a recommendation to use it.
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.
Same view — ApoB if you add one thing. It answers a question the standard panel only gestures at.
Brought the whole set to my clinician rather than one flagged value. Completely different conversation.
one measurement is a point, two is a line, three is a trend
hydration status moves a surprising number of markers
What did the repeat show?
Careful — that is a question for whoever ordered the panel, and nobody in this thread can answer it responsibly.
Have you taken this to whoever ordered it?
Left up. It is a question about how to compare panels, not a request for interpretation.
Left up.
This is the sentence to read before anybody panics about a single value.
My hs-CRP moved and I spent a fortnight convinced I knew why. The repeat six weeks later was back in range and I had changed nothing.
baseline before you start is worth more than any later panel
bring the numbers to someone qualified to read them
Substantial weight loss independently moves lipids, liver enzymes and several other markers. Attributing a change to a compound while losing weight is confounded by design.
ask whether the lab changed its assay between your two draws
