REFERENCE CALCULATIONS
Anticoagulant
in Product
The concentration of anticoagulant in a platelet or plasma product is a function
of the Anticoagulation Ratio (“AC Ratio”) and Donor Hematocrit.
Table 7-1 gives
the concentration of anticoagulant in the collected plasma or platelet product.
To determine the total volume of anticoagulant in a plasma or platelet product
use the following procedure:
• Determine the concentration of anticoagulant in the product from Table
7-1.
• The total volume of anticoagulant in collected products can be calculat-
ed by multiplying the concentration of anticoagulant in the plasma by
the volume of the product:
