Donor Criteria for Collection of 2 Red Blood Cell Products By Apheresis

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%

Minimum height:

(1) for males: >= 5 feet, 1 inch (61 inches)

(2) for females: >= 5 feet, 5 inch (65 inches)

Gender	Body Weight	Absolute RBC Volume in mL per Product
female	< 150 lbs	NA
female	150 - 174 lbs	180 mL
female	>= 175 lbs	200 mL
male	< 130 lbs	NA
male	130 - 149 lbs	180 mL
male	150 - 174 lbs	200 mL
male	>= 175 lbs	210 mL

where:

• 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)
