Additional information was added to d10, h3, h4, and h6.H10: two (2) devices were received for evaluation.A visual inspection was performed, and it was noted that there was yellowish discoloration in the micron low volume filter.All components were correctly placed and according to specifications.Additionally, functional testing was performed including pressure and clear passaged testing.During functional testing, there was no leak noted; however, a blockage was discovered in the micron low volume filter.The reported condition was verified.The cause of the reported condition could not be determined; however, a probable cause may have been a user error as the yellow discoloration resembled spherical particles suggestive of a mixture of amino acids which would be consistent with tpn solution residue, which also could block the filter.A batch review was conducted and there were no deviations found related to this reported condition during the manufacture of this lot.Should additional relevant information become available, a supplemental report will be submitted.
