  • Practitioner and patient names

Acceptable specimens:

  • Whole blood collected in proprietary vacutainer tubes (white top) from properly prepared patient (see required test preparation instructions) and drawn with 19 gauge needed, provided.

  • Send 4 tubes for all panels except All Inclusive, which requires 8 tubes. Contact EAB Client Services for guidance if a full specimen can’t be collected.
  • Tubes should be fully filled. Partially filled tubes will not have the proper ratio of blood to additive.
