Critical Titer:
This is another rare antibody for sure. I could only find 2 articles that even mentioned anti-Zd when searched. Because of this, I have taken the liberty of uploading my copy of the full text of article 1 below. So far this antibody/antigen combo have only been found in 1 family. Anti-Zd is a warm reacting antibody that crosses the placenta [2]. Anti-Zd can cause HDN requiring an exchange transfusion [1].
