Highlights from this day

salt_bridge — this is the list people here work from. it is not a prescription and your clinician may not order all of it 06:41
salt_bridge — and what each one is actually for 07:36
sage_sources — *mg/dL glucose and micro-units per ml insulin. if your lab reports mmol/L it is a different divisor 08:40
tenpence — and if anything comes back out of range, that is a conversation with whoever ordered it, not with us 08:45
bea_reconstitutes — my own baseline with the identifiers blacked out, so you know what you will be handed 09:37

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

what would make you stop and go and see somebody rather than post here
i pay privately for fasting insulin because nobody will order it for me otherwise

my alt has come down a lot since i started losing, is that expected

Assay note: WWB lot A-2601 reported at 99.4% of label content.

two_three_lifts 05:44

probably dehydration

is it too early to retest a1c at week 2
my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all

genuine question coming back after 1 months, what changed in your numbers

group_buy_gwen 05:48

is a fasting insulin worth paying for privately if my gp will not do it

⚠️14😂18

month_six_me 05:53

fasting insulin

month_six_me 06:10

genuine question i pay privately for fasting insulin because nobody will order it for me otherwise

group_buy_gwen 06:11

an isolated lipase a bit over range with no symptoms is usually nothing. lipase with severe pain is not

[edited]

a1c is a ninety day average. retesting at week six tells you almost nothing

month_six_me 06:13

anyone had a result that turned out to be a lab error

juno_joins 06:15

starting in two weeks. what should i get tested first

bea_reconstitutes 06:16

before, not after. that is the whole point of the word baseline

salt_bridgelab06:41

this is the list people here work from. it is not a prescription and your clinician may not order all of it

CMP / U+E + LFTs      - sodium, potassium, creatinine, eGFR, ALT, AST, ALP, bilirubin
lipids, fasting       - total, LDL-C, HDL, triglycerides, and apoB if you can get it
HbA1c                 - the three month average
fasting glucose       - same draw as the insulin
fasting insulin       - so you can compute HOMA-IR
CBC / FBC             - haemoglobin, platelets, white cells
TSH (+ free T4)       - because fatigue in month four needs a starting point
ferritin, B12, folate - your intake is about to drop

juno_joins 06:42

that is a lot of tubes

sage_sources 06:43

it is one draw

bea_reconstitutes 06:44

and it is the only chance you will ever get to know what you looked like before

juno_joins 06:45

can i just get the cheap panel

salt_bridgelab06:47

you can. the two you will regret skipping are fasting insulin and apoB

everyone measures A1c and nobody measures insulin, and insulin is the one that moves first

sage_sources 06:49

mine halved before my A1c had shifted at all

👀6

juno_joins 06:50

why does A1c lag

salt_bridgelab06:51

it is glycated haemoglobin. red cells live around 120 days, so the number is a weighted average — skewed to the last month but not only the last month

so leave three months between draws or you are measuring the same blood twice

bea_reconstitutes 06:55

people retest at week six, see nothing, and panic. that is the whole trap

juno_joins 07:15

ok so bloods now, then three months

bea_reconstitutes 07:33

three months for A1c and lipids. insulin you can look at sooner if you are curious

VialBotbot07:34

reminder set — @juno_joins baseline retest window opens 2026-11-02 (12 weeks). i will nudge this channel.

juno_joins 07:35

the bot is keeping my diary for me now. excellent

salt_bridgelab07:36

and what each one is actually for

Marker	Why it is on the list	What people watch
HbA1c	glycaemic average	direction over 3+ months, never week to week
fasting insulin	earliest mover	falls well before A1c does
HOMA-IR	insulin x glucose, over a constant	trend only, and only from a fasting draw
apoB	atherogenic particle count	can stay high while LDL-C looks fine
ALT	liver fat proxy in this population	usually drifts down as visceral fat goes
eGFR	renal function estimate	a small early dip is not automatically bad
ferritin / B12	intake dependent	where fatigue and hair questions start
