The heparin concentration is approximately 15 USP (US Pharmacopeia) units of heparin per milliliter of blood. The USP is not equivalent to the International Units (IU). The IU is 6.4% greater than the USP.

Prior to April 1, 2010, the heparin concentration is approximately 15 USP (US Pharmacopeia) units of heparin per milliliter of blood. The USP is not equivalent to the International Units (IU). The IU is 6.4% greater than the USP. As of April 1, 2010, if a sodium or lithium heparin tube has a capital N superscript alphabetic character following the word Heparin (i.e.HeparinN), the USP and IU are equivalent. You will also see a numerical change in the number of USP Activity Units as a result of the harmonization to the WHO International Standard. Please refer to the BD electronic catalog for details on the specific product that you are interested in. There are no changes in the design or clinical performance of the BD Vacutainer® Tubes with Lithium Heparin or Sodium Heparin Additives. This is a labeling change only.
