Highlights from this day
- monoisotopic — my b12 is borderline, supplementing or eating differently 11:29
- appetite_back — my potassium came back weird and the retest was normal, whats that about 13:29
- amsterdam_aliquot — ok so do you fast for the full 12 hours or is 8 enough 14:23
- apob_over_ldl — do you get bloods every 6 months or only when something changes 15:32
- manila_meniscus — a1c is a ninety day average. retesting at week six tells you almost nothing 17:39
is a fasting insulin worth paying for privately if my gp will not do it
my b12 is borderline, supplementing or eating differently

thats the 90 day thing
post the numbers
👍3😂3👀5
fasting insulin
how much does the lipid panel move just from losing weight
lab error maybe
alt and ast coming down as you lose liver fat is common and is a good sign, i think
is there any point getting a1c if i am not diabetic
what would make you stop and go and see somebody rather than post here
🧪3🔥1
genuine question my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all
is it too early to retest a1c at week 2
not a chat question
thyroid moving slightly is common enough that i would repeat it before doing anything
see somebody
homa-ir is fasting glucose times fasting insulin over a constant. the constant differs by unit system
⚠️4
a single weird electrolyte is very often a handling artefact. retest before you worry
my potassium came back weird and the retest was normal, whats that about

update on the earlier thing i pay privately for fasting insulin because nobody will order it for me otherwise
if a result frightens you, that is a conversation with a clinician. we will help you read it, we will not tell you it is fine
if your glucose is in mg/dL the divisor is 405. if it is mmol/L it is 22.5
fast properly or do not bother. an eight hour fast and a twelve hour fast are different tests
if you only get one thing, get a fasting insulin. it is the one that becomes impossible later
thats normal
| Test | Why now |
|---|---|
| Fasting insulin | impossible to get a true baseline afterwards |
| Full lipid panel with apoB | the comparison is the whole point |
| HbA1c | 90-day average, so it lags your start |
| CMP + CBC | cheap, and the reference for everything after |
| Ferritin, B12, TSH | these fall quietly on a low intake |
ok so do you fast for the full 12 hours or is 8 enough
❤️1🎉3💀3
anyone had a result that turned out to be a lab error
⚠️2😂2
right so crp is worth adding if you can, it moves in a useful direction on this
anyone have before and after numbers they are willing to post
update from 8 months ago: a1c down, apob unchanged, and i am genuinely annoyed about the apob
the FLOW result is why my nephrologist changed her position on this entirely
good numbers
get fasting insulin at baseline. you cannot go back and get it once you have started
retest it
do you get bloods every 6 months or only when something changes
probably dehydration
a small egfr dip is often dehydration. rehydrate and retest before you panic
apob or ldl, which one are you all actually tracking
an isolated lipase a bit over range with no symptoms is usually nothing. lipase with severe pain is not
what should i get at baseline before i start
baseline, three months, then twice a year is what i settled on
while im here most of the lipid improvement in my panel tracked the weight, not the drug
too early for a1c
the FLOW result is why my nephrologist changed her position on this entirely
a1c is a ninety day average. retesting at week six tells you almost nothing

i had a potassium that came back high and the repeat was normal. the tube had been knocked about
mine did the same

nobody here is reading your bloods as a clinician. we are reading them as people who have had a lot of bloods, your mileage will differ
