comment on anyone else notice resistance training kicking in around week 92 in c/glp1muscle · 16 points · 8 months ago
losing weight slower does not automatically preserve more lean mass
comment on dead space is the most under-discussed thing on this board in c/reconstitution · 12 points · 8 months ago
a U-100 syringe reads 100 units to the millilitre, every time
comment on test results — 21 things I got wrong before I got it right in c/labresults · 31 points · 9 months ago
Split one vial between Janoshik and VendorInvestigate. The two numbers were within half a point of each other and I stopped worrying about which lab to trust.
comment on [Question] below spec — what am I missing here in c/labresults · 95 points · 10 months ago
I would not post that as a finding. It is a single result and the template asks you to say so.
comment on mg/mL is the most under-discussed thing on this board in c/reconstitution · 396 points · 10 months ago
Right — the volume you add is the only variable you control here, and the cake does not change it meaningfully.
comment on batch is the most under-discussed thing on this board in c/labresults · 173 points · 10 months ago
Careful with the trend claim. Four results over two years is a very sparse series to draw a line through.
comment on [Discussion] the test results advice in here is 2 years out of date in c/labresults · 46 points · 11 months ago
Inter-lab variance on this assay runs roughly a point either way, driven mostly by gradient and integration. Two results inside that band agree; they do not disagree quietly.
comment on genuine question about MASH that I am slightly embarrassed to ask in c/survodutide · -27 points · 1 year ago
Which endpoint — histological response, fibrosis improvement, or fat fraction?
comment on [Question] how do you actually verify bacteriostatic water in c/reconstitution · 1 points · 1 year ago
units are a volume on a U-100 syringe, not a dose
comment on the copay thing finally clicked for me and I want to write it down in c/insurancefights · 43 points · 1 year ago
Prior authorisation criteria are republished each plan year. A criterion that blocked you in one year may not exist in the next, so a denial is worth retesting after the turnover.
comment on the dead space question that gets asked weekly, answered properly in c/reconstitution · 6 points · 1 year ago
The arithmetic in full: concentration is mass over volume, so 15mg into 3mL gives 5mg/mL. A U-100 syringe is graduated at 100 units per millilitre, so 0.75mg is 0.75 divided by 5 millilitres, which is 15 units.
comment on three years of MASH threads, summarised so you do not have to read them in c/survodutide · -9 points · 1 year ago
Right, and the trial titration was slow for reasons that are visible in the tolerability tables.
comment on resistance training — 15 things I got wrong before I got it right in c/glp1muscle · 8 points · 1 year ago
Agreed on the error margin. Quoting a DEXA to one decimal implies a precision the method does not have.

Internal appeals are decided by the plan.
Adding the underused one — external review. Independent, binding where it applies, and hardly anybody gets that far.
comment on reading below spec threads from 2024 and half of it aged badly in c/labresults · 31 points · 1 year ago
Yes — date of analysis, because a result from two years ago describes a different manufacturing month.
comment on reading below spec threads from 2024 and half of it aged badly in c/labresults · 37 points · 1 year ago
the log is cumulative, that is the whole value of it
comment on genuine question about dual agonist that I am slightly embarrassed to ask in c/survodutide · 1 points · 1 year ago
fibrosis improvement without worsening steatohepatitis is the phrase to learn
comment on the bacteriostatic water question that gets asked weekly, answered properly in c/reconstitution · 25 points · 1 year ago
aim the stream at the glass wall, not at the cake
comment on units are the most under-discussed thing on this board in c/reconstitution · 25 points · 1 year ago
Correction: that gives 100 units, not what you have written. 15mg into 3mL is 5mg/mL and the division follows from there.
comment on help me understand PeptideMeter, I have read the wiki twice in c/labresults · 148 points · 1 year ago
Sent a vial in specifically to check a supplier’s claim after a good experience. It matched. Boring result, worth logging.
comment on help me understand PeptideMeter, I have read the wiki twice in c/labresults · 126 points · 1 year ago
Split one vial between VendorInvestigate and Medutest. The two numbers were within half a point of each other and I stopped worrying about which lab to trust.

results without method are gossip with decimals
comment on someone explain mg/mL to me like I have not read a paper in years in c/reconstitution · 9 points · 1 year ago
That only works if the fill weight is exactly the label weight, and it usually is not exactly anything.
comment on hepatic fat — 19 things I got wrong before I got it right in c/survodutide · 21 points · 1 year ago
Nothing containing this compound is approved anywhere. Research-use-only material is not approved for human use.
comment on [Discussion] New Zealand is doing more work than we give it credit for in c/glp1aus · 36 points · 1 year ago
ask the pharmacy to check the wholesaler rather than guessing
comment on reading resistance training threads from 2024 and half of it aged badly in c/glp1muscle · 33 points · 1 year ago
strength retention is a decent proxy and it is free
comment on [Meta] the Janoshik rule is doing its job and people should stop complaining in c/labresults · 241 points · 1 year ago
Inter-lab variance on this assay runs roughly a point either way, driven mostly by gradient and integration. Two results inside that band agree; they do not disagree quietly.
comment on how much of what we believe about appeal actually comes from step therapy threads in c/insurancefights · 48 points · 1 year ago
ask for the denial reason in writing, always
comment on [Meta] the Medutest rule is doing its job and people should stop complaining in c/labresults · 124 points · 1 year ago
If the report gives a mass spectrum as well as UV purity, say so. Identity and relative quantity are separate claims and the log tracks both.
comment on [Discussion] the denial advice in here is 3 years out of date in c/insurancefights · 3 points · 1 year ago
Disagree with the tone strategy. Anger has never moved a determination; matching the criterion has.
comment on [Discussion] can we stop arguing about reconstitution until somebody posts a number in c/reconstitution · 1 points · 1 year ago
Show the arithmetic — where did the unit figure come from?
comment on [Discussion] the PBS advice in here is 3 years out of date in c/glp1aus · -6 points · 1 year ago
Australia and New Zealand have different regulators, different funding bodies and different arrangements. An answer for one is not evidence about the other.
comment on do test results actually matter or is it forum lore at this point in c/labresults · 108 points · 1 year ago
the log is cumulative, that is the whole value of it
comment on Medutest — 8 things I got wrong before I got it right in c/labresults · 1 points · 1 year ago
The template is vendor, compound, batch, service, claim, result, and who paid. Every one of those fields exists because a result missing it has been argued about here before.
comment on [Discussion] the below spec advice in here is 2 years out of date in c/labresults · 31 points · 2 years ago
three lots beats three tests on one lot
comment on [Discussion] the purity advice in here is 2 years out of date in c/labresults · 119 points · 2 years ago
split a vial across two services once and you will never argue about ground truth again
comment on how much of what we believe about Australia actually comes from New Zealand threads in c/glp1aus · 0 points · 2 years ago
Small fix — that is the New Zealand arrangement, and the question is about Australia.
comment on unpopular opinion: most of what gets said here about denial is guesswork in c/insurancefights · 135 points · 2 years ago
Yes. Written, always, even when they tell you a phone call is sufficient.
comment on [Question] how do you actually verify insulin syringe in c/reconstitution · 7 points · 2 years ago
Yes, and the dead-space point is worth repeating: it is small, it is real, and it is the same for every draw.
