a small egfr dip is often dehydration. rehydrate and retest before you panic

Highlights from this day
- vial_ledger — coming back to this my potassium came back weird and the retest was normal, whats that about 15:27
- fasting_insulin — my alt has come down a lot since i started losing, is that expected 16:17
- lot_number_lou — thyroid moving slightly is common enough that i would repeat it before doing anything 16:23
- warsaw_vial — a1c is a ninety day average. retesting at week six tells you almost nothing 17:08
apob is the better marker and it is harder to get. i track both because i can only get one reliably
the FLOW result is why my nephrologist changed her position on this entirely, ymmv
fast properly or do not bother. an eight hour fast and a twelve hour fast are different tests
too early for a1c
how much does the lipid panel move just from losing weight
coming back to this my potassium came back weird and the retest was normal, whats that about
| 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 |
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

update from 11 months ago: a1c down, apob unchanged, and i am genuinely annoyed about the apob, we shall see

is a fasting insulin worth paying for privately if my gp will not do it
ferritin and b12 fall quietly when you are barely eating. check them twice a year
nobody here is reading your bloods as a clinician. we are reading them as people who have had a lot of bloods, ill dig out the number

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

my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all
is it too early to retest a1c at week 29
thyroid moving slightly is common enough that i would repeat it before doing anything
nice a1c
do you get bloods every 5 months or only when something changes
fasting insulin
what would make you stop and go and see somebody rather than post here

coming back after 20 months, what changed in your numbers
i had a potassium that came back high and the repeat was normal. the tube had been knocked about
the most useful thing i did was get a full panel before i started. everything since has been comparable, ask me again in a month
a1c is a ninety day average. retesting at week six tells you almost nothing

*week 15 not week 4
most of the lipid improvement in my panel tracked the weight, not the drug
lab error maybe
