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

Highlights from this day
- seven_five_sweet — ferritin and b12 fall quietly when you are barely eating. check them twice a year 15:12
- seven_five_sweet — what does homa-ir actually tell you that fasting insulin does not 15:59
- sgp_subq — fasting insulin came back higher than i expected, what does that actually mean 16:33
- dexa_or_bia — a small egfr dip is often dehydration. rehydrate and retest before you panic 17:17
- sgp_subq — if you only get one thing, get a fasting insulin. it is the one that becomes impossible later 18:13
ferritin is low, is that the drug or the not eating

quick one alt and ast coming down as you lose liver fat is common and is a good sign
egfr dropped a few points, dehydration or something real
if your glucose is in mg/dL the divisor is 405. if it is mmol/L it is 22.5
my alt has come down a lot since i started losing, is that expected
| 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 |
post the numbers
the FLOW result is why my nephrologist changed her position on this entirely
is a fasting insulin worth paying for privately if my gp will not do it

while im here get fasting insulin at baseline. you cannot go back and get it once you have started
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
retest it
🔥1💀4
i pay privately for fasting insulin because nobody will order it for me otherwise
baseline, three months, then twice a year is what i settled on
most of the lipid improvement in my panel tracked the weight, not the drug
anyone have before and after numbers they are willing to post
triglycerides halved. is that the weight or the compound
a single weird electrolyte is very often a handling artefact. retest before you worry

what does homa-ir actually tell you that fasting insulin does not
😂18📉1🧊15
crp is worth adding if you can, it moves in a useful direction on this
the most useful thing i did was get a full panel before i started. everything since has been comparable

fasting insulin came back higher than i expected, what does that actually mean
📈7😂14
homa-ir is fasting glucose times fasting insulin over a constant. the constant differs by unit system
a1c is a ninety day average. retesting at week six tells you almost nothing
is it too early to retest a1c at week 24
thyroid moving slightly is common enough that i would repeat it before doing anything
🔥6
is crp worth adding to the panel
nobody here is reading your bloods as a clinician. we are reading them as people who have had a lot of bloods
fast properly or do not bother. an eight hour fast and a twelve hour fast are different tests, for what its worth
a small egfr dip is often dehydration. rehydrate and retest before you panic

is there any point getting a1c if i am not diabetic
apob is the better marker and it is harder to get. i track both because i can only get one reliably, i could be wrong
nice a1c
not a chat question
get a baseline
quick one 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

fasting insulin
probably dehydration
update from 18 months ago: a1c down, apob unchanged, and i am genuinely annoyed about the apob, we shall see
see somebody
📈2
do you fast for the full 12 hours or is 8 enough
mine did the same
lab error maybe
quick one good numbers
fasting insulin
my b12 is borderline, supplementing or eating differently
my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all, ask me again in a month
thats a big move
⚠️2💀13
thats the 90 day thing
apob if you can
thats the 90 day thing
