Does the analysing laboratory make allowance for the probable 10% error in
sample volume or the dilution of the creatinine if using a ratio ?

Regarding acidified urines.
I use 60 mL of 1.5 M HCl instead of 15 mL of 6 M HCl. One could equally
well use 120 mL of 0.75 M HCl. In any case, the 1.5 M is much less
aggressive than the 6 M, and perhaps the larger volume makes clients more
aware of the need to be careful.
