2nd aliquot (pH 9): Transfer 4 mL urine to the sodium carbonate tube. Mix well, then freeze.
3rd aliquot: Transfer 4 mL urine to an unpreserved tube. Mix well, then freeze.
4th aliquot: Transfer 4 mL urine to an unpreserved tube. Mix well, then freeze.
If collection kit is unavailable, transport four 4 mL unadjusted aliquots of urine.
