It is possible to avoid issuing urine collection bottles containing acid if
the urine is acidified after collection. Ortho recommend for their Vitro
analysers that 2.0mL 6M HCl is added for every 100mL urine collected and
then well mixed. Alternatively add 400uL 6M HCl to a 20mL aliquot of urine
taken from a well mixed collection. The Vitros analysers correct for this
dilution of urine but for other methods it would be necessary to allow for
this in your calculations.
