Baseline panels, ApoB, A1c, liver enzymes. Track it, do not guess.
get these before you start, you cannot go back for them later. Making the case below, and I expect to lose some of it in the comments. Added ApoB to the panel after a…
Reference range on my lab is 15–200 ng/mL. Mine came back 9. Haemoglobin was still just inside range, which is why nobody had caught it. Marker Month 0 Month 8 Range…
ApoB over LDL-C and i will keep saying it, and I am aware this is a minority view on this board. How to make a panel worth comparing, which is most of the value people…
ALT 34 → 19 in seven months, nothing else changed. Numbers below. Ask me the boring questions, they are the useful ones. Brought the whole set to my clinician rather…
Vendor-level purity averages over time, built from independent results rather than vendor claims. Transparent methodology, open dataset.
Browse resultseGFR dropped 8 points during rapid loss, should i worry. If this has been answered properly somewhere, link me and I will delete. The confounding problem, stated…
The title is the argument: ferritin 9. i was eating 1,100 calories and calling it discipline. Here is the rest of it. Reference intervals are typically the central 95%…
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…
A1c 9.1 → 5.4 over 14 months, full table inside, which sounds obvious until you try to state the evidence for it. Since the title puts numbers in the shop window: 14…
hs-CRP halved before the scale moved much, logged the same way every week so the comparison is at least internally fair. Compared two draws across two labs and spent a…
The title is the whole question — my TSH moved 0.4. is that anything — but here is why I am asking. Brought the whole set to my clinician rather than one flagged value.…
units differ by country, post your reference ranges or nobody can help, which sounds obvious until you try to state the evidence for it. Brought the whole set to my…
lipids got worse on paper while everything else got better. triglycerides explain it. It is the sort of thing everyone half-believes and nobody writes down. My A1c…
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…
47 weeks, 8kg, and ferritin was the hard part, logged the same way every week so the comparison is at least internally fair. Hard numbers: 47 weeks and 8kg. Anything…
week 67 check-in — 10kg down, muscle cramps manageable, one thing confusing me. Numbers below. Ask me the boring questions, they are the useful ones. Since the title…
Reference standards, analytical reagents and system-suitability material. If you are running your own method, start with a known.
Reference standardsproposal — a flair for ferritin posts. Disagreement welcome, but bring a concrete alternative wording. Different laboratories use different assay platforms with…
the ALT advice in here is 2 years out of date. Making the case below, and I expect to lose some of it in the comments. To save the first four comments: 2 years. My ApoB…
unpopular opinion: most of what gets said here about eGFR is guesswork. I have gone back and forth on this for months. How to make a panel worth comparing, which is…
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…
we are measuring A1c at the wrong time and calling it noise, and I am aware this is a minority view on this board. Compared two draws across two labs and spent a week…
tried A1c for 18 weeks. here is what happened, and I am aware this is a minority view on this board. 18 weeks. Those are measured, not estimated, and not rounded up in…
ferritin — 20 things I got wrong before I got it right, which sounds obvious until you try to state the evidence for it. Nobody here can interpret your panel and this…
the bloodwork thing finally clicked for me and I want to write it down. Not a hot take, just something I have not seen said plainly here. ApoB counts atherogenic…
The title is the argument: unpopular opinion: most of what gets said here about baseline labs are guesswork. Here is the rest of it. Reference intervals are typically…
am I the only one who found ferritin harder than the injections. I am not trying to be the "source?" guy. I would just like a source. Different laboratories use…
What to measure before you start, what to re-measure, and how to interpret movement without panicking. ApoB over LDL-C, HOMA-IR as a crude free tool, ALT and the fatty-liver story, eGFR noise during rapid loss, and the deficiencies that a 1,100-calorie appetite will hand you.
Independent HPLC and mass spec. The number you get is the number they found.
