<p>It is important to isolate autologous red blood cells (RBCs) from transfused RBCs in samples from recently transfused patients to ensure that accurate serologic results are obtained. Typically, this isolation can be performed using methods that separate patient reticulocytes from transfused, older donor RBCs. Patients with sickle cell disease (SCD), however, characteristically have RBCs with altered membrane and morphological features, causing their RBCs to take on a sickle-shape appearance different from the biconcave disc-shape appearance of “normal” RBCs. These characteristics enable the use of hypotonic saline solution to lyse normal RBCs while allowing “sickle cells” to remain intact. Because many patients with SCD undergo frequent transfusions to treat their condition, the use of hypotonic saline solution provides a rapid method to obtain autologous RBCs for serologic testing from this patient population using standard laboratory equipment and supplies. <italic><bold>Immunohematology</bold></italic> <bold>2018;34: 16–18.</bold></p>
