Of course…you explain what's 'international'…
... if alcohol were a solid in room temperature
... Alcohol is indeed liquid at room temperature, but alcohol in water is a solution. Solute is expressed by its mass (volume of some solutes may vary a lot with temperature, pressure). Alcohol is also a substance chemically active in the human system, a drug/medicament (as well as an energy fuel for cell metabolism). Since a human person is not a bottle of drink (there, the volume tells everything you need to now) maybe, in many countries doctors do consider it as a drug rather than as a liquid, because concentrations of all chemically active molecules (drugs, medicaments) is always referred to by their mass amount.
Going a bit overboard with the emoticons there?
Perhaps you can give me a cite that liquids in solution in other liquids are always expressed in mass-per-unit-volume measures. I'll enjoy waiting for that.... (PS: what about the changing volumes of the solvent with temperature or pressure? Doesn't this mean (per your "argument") that concentrations should in fact be given in mass-per-unit-mass? Oops!)
Oh, and while you're at it, perhaps you can explain why liquid medicines (morphine, cyclizine etc) are given in volume form. That seems to be in conflict with your "argument".
… “massive and fundamentally important difference”… you magnify properties of a TMB test which you maybe pompously call “proper” (because of the “two stages” ! ), you say I “obviously didn’t study science beyond a very basic level…”
… and then you write… “the peroxide catalyser” . (!)
You go on explaining repeating that peroxide is the catalyser.It is an oxidant. Hemoglobine is the catalyser.
It's already very clear that you don't understand the science here regarding the TMB test. Who knows, perhaps you DO now at least understand that the two-part TMB test is necessarily far higher specificity than the Hemastix test. If you do, it's interesting that you hide any acknowledgement about that behind further attacks on small inconsequential matters. Interesting indeed.
Oh, and I realise you may have googled some scientific literature that mentions "peroxide" and "oxidant" in the same sentence, and that you may have got excited because you thought you'd "caught me out". Well, bad luck. Peroxide is indeed the oxidant, but its role in this TMB test is also to act as the catalyser of the reaction with the iron. And (oops) Haemoglobin (or "hemoglobin" in the US, but most definitely never "hemoglobine") is the catalyst, not the catalyser. That you don't know the difference between these two terms tells me all I need to know.
Who'd have thought it? Two "epic fail" attempts at arguments within 24 hours!
