reading eGFR threads from 2024 and half of it aged badly. I have gone back and forth on this for months. Different laboratories use different assay platforms with…
c/bloodwork — hot, page 4
Positions 76–95 of 95.
ALT is not what most of this community thinks it is. That is the post. The justification is underneath. Time of day, fasting state, hydration and recent exercise all…
Something I keep coming back to: nobody warned me about reflux and I would have liked the warning. Added ApoB to the panel after a thread here. It told me something the…
stalled for 13 weeks at 2.4mg and I refuse to panic this time. I have gone back and forth on this for months. 13 weeks and 2.4mg. Those are measured, not estimated, and…
Sigma-Aldrich — certified reference materials
Reference standards, analytical reagents and system-suitability material. If you are running your own method, start with a known.
Reference standardsbaseline labs are the most under-discussed thing on this board. Making the case below, and I expect to lose some of it in the comments. Time of day, fasting state,…
Question in the title, detail here: can we stop arguing about ApoB until somebody posts a number. Reference intervals are typically the central 95% of a reference…
the baseline labs question that gets asked weekly, answered properly. Change my mind, genuinely — I have no stake in being right about this. Repeat testing before…
Posting this as a discussion rather than a claim: ALT — 4 things I got wrong before I got it right. Why so many single values look alarming and turn out to be nothing.…
Question in the title, detail here: how much of what we believe about ApoB actually comes from baseline labs threads. Reference intervals are typically the central 95%…
anyone else notice baseline labs kicking in around week 7. This is a description of what happened to me and not a plan for anybody else. Why so many single values look…
how much of what we believe about A1c actually comes from ferritin threads, and I want the answer with the reasoning attached rather than just the conclusion. Compared…
The one-line version is the title: lipids are not what most of this community thinks it is. The rest is why. Brought the whole set to my clinician rather than one…
the ApoB question that gets asked weekly, answered properly, which sounds obvious until you try to state the evidence for it. Nobody here can interpret your panel and…
proposal — a flair for baseline labs posts. Comments open, and the wording is genuinely up for discussion. Time of day, fasting state, hydration and recent exercise all…
Genuine question, and the title is the question: what changed for me between month 2 and month 11. Added ApoB to the panel after a thread here. It told me something the…
Janoshik Analytical — independent HPLC & mass spec

glbiochem.netwhat would you tell week-1 you about ferritin — that is what I am asking, and I have already read the wiki twice. Draw at the same point in the week now, fasting, same…
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…
Check-in as promised in the title: 78 weeks on 12.5mg, full numbers, ask me anything boring. 78 weeks and 12.5mg. Those are measured, not estimated, and not rounded up…
which labs are worth repeating quarterly and which are theatre. That is the post. The justification is underneath. Panicked about a single result, posted here, got told…
HOMA-IR is crude and free, track it anyway. If you already knew this, the post is not for you and you can scroll on. ApoB counts atherogenic particles rather than the…
