Apheresis can be used to collect 2 red blood cell products from a single donor ("2RBC") provided the donor meets certain clinical criteria.
Number of RBC products collected: 2
Minimum hematocrit: >= 40%
(1) for males: >= 5 feet, 1 inch (61 inches)
(2) for females: >= 5 feet, 5 inch (65 inches)
Absolute RBC Volume in mL per Product
< 150 lbs
150 - 174 lbs
>= 175 lbs
< 130 lbs
130 - 149 lbs
• The RBC volume is the total RBC volume. The volume that can be collected can be estimated from the desired hematocrit for the product:
volume of blood product in mL =
= (absolute RBC volume in mL) / (desired hematocrit for product)
