The blood bank tip geometry is optimized for even, reproducible drop delivery in ABO\/Rh typing, direct and indirect antiglobulin testing (DAT\/IAT), antibody identification panel reading, and compatibility crossmatch procedures. The ~40 µL drop volume is calibrated to the serum:cell ratios specified in standard blood bank tube method protocols (AABB Technical Manual, manufacturer reagent IFU), where over-delivery or under-delivery of a single drop shifts the effective serum:cell ratio enough to affect agglutination strength. At 500\/Bag sterile individually packed, this format provides the single-use contamination control required for patient-specific blood bank testing.\u003c\/p\u003e \u003ch2\u003eU.S. Manufacturing, Quality \u0026amp; Institutional Procurement\u003c\/h2\u003e \u003cp\u003eCaplugs® Evergreen products are manufactured in the United States under ISO 9001 quality management from FDA-compliant, food-contact-grade resins.
