Q. What is the appropriate way to measure or identify microcytosis or macrocytosis? Read answer.
Q. A six-year-old female with B-cell acute lymphoblastic leukemia and Rh-negative blood is being treated with myeloablative chemotherapy to achieve durable remission or as a bridge to stem cell transplantation, during which supportive transfusions will include repeated platelet transfusions over many weeks. Clinicians are concerned that the patient could become alloimmunized to the D antigen, which, in turn, could affect her ability to eventually bear children.
Apheresis platelets contain a small but finite amount of RBC contaminants, which are not usually quantitated. An optimal strategy to prevent anti-D alloimmunization is to use Rh-negative platelets, but they are often in short supply and cannot be ordered stat in a timely enough manner to ensure every platelet transfusion episode is Rh-negative. We considered using Rh immune globulin (RhIg). However, we recognize that commercial RhIg is designed to prevent D alloimmunization in the setting of obstetric fetal-maternal bleeding.
Is there an optimal dose for RhIg or suggested timing of administration to prevent anti-D alloimmunization in this setting? Read answer.

December 2022—To safely and effectively extend the process of conducting point-of-care testing to staff from various hospital departments is no easy feat. That’s why four full-time employees at Children’s Hospital Los Angeles oversee POC testing, relying heavily on middleware, analytics, and exception-management tools.

December 2022—The Food and Drug Administration has approved the Ventana FOLR1 (FOLR1-2.1) RxDx Assay, the first immunohistochemistry companion diagnostic test to aid in identifying epithelial ovarian cancer patients who are eligible for targeted treatment with Elahere (mirvetuximab soravtansine-gynx). Elahere is a first-in-class antibody-drug conjugate therapy developed by ImmunoGen and approved under the FDA’s accelerated approval program for the treatment of FRα-positive platinum-resistant ovarian cancer.
