Erythrocyte concentrates are filtered over a leukocyte-removing filter in order to eliminate most of the leukocyte content.
Volume: the filtering process causes a loss of 47.4 ml.
Erythrocytes: 84% of the initial erythrocyte content is recovered.
Leukocytes: the final leukocyte content varies between 0.5 x 105 and 4.4 x 105.
Collapsible plastic bags.
By labels stating: name of centre, type of product, ABO group and Rh (D) factor, unit number, date of extraction, expiry date, results of completed analysis, type of anticoagulant, and instructions for storage and administration.

The process of filtering erythrocyte concentrates, if performed in a closed circuit, does not affect the shelf life. If the process is not performed in a closed circuit, the expiration date is 24 hours after filtering.
Erythrocyte concentrates may be fractionated into subunits.
