for the archive apob is the better marker and it is harder to get. i track both because i can only get one reliably

Highlights from this day
- apnoea_down_two — the FLOW result is why my nephrologist changed her position on this entirely 22:29
- new_here_nat — follow up an isolated lipase a bit over range with no symptoms is usually nothing. lipase with severe pain is not 22:36
- new_here_nat — get fasting insulin at baseline. you cannot go back and get it once you have started 22:37
follow up apob or ldl, which one are you all actually tracking
a small egfr dip is often dehydration. rehydrate and retest before you panic

right so update from 18 months ago: a1c down, apob unchanged, and i am genuinely annoyed about the apob
if you only get one thing, get a fasting insulin. it is the one that becomes impossible later

ferritin and b12 fall quietly when you are barely eating. check them twice a year

get fasting insulin at baseline. you cannot go back and get it once you have started
| 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 |
baseline, three months, then twice a year is what i settled on
crp is worth adding if you can, it moves in a useful direction on this
for the archive anyone have before and after numbers they are willing to post
sorry to jump in i pay privately for fasting insulin because nobody will order it for me otherwise
thyroid moving slightly is common enough that i would repeat it before doing anything
is it too early to retest a1c at week 26
i had a potassium that came back high and the repeat was normal. the tube had been knocked about
homa-ir is fasting glucose times fasting insulin over a constant. the constant differs by unit system

genuine question anyone had a result that turned out to be a lab error
thats a big move
thats the 90 day thing
is a fasting insulin worth paying for privately if my gp will not do it
good numbers
what should i get at baseline before i start

a single weird electrolyte is very often a handling artefact. retest before you worry
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
right so a1c is a ninety day average. retesting at week six tells you almost nothing

if your glucose is in mg/dL the divisor is 405. if it is mmol/L it is 22.5
get a baseline
