Donath-Landsteiner testing was positive for biphasic hemolysin with hemolysis occurring at 37C after incubation at 4C confirming the diagnosis of paroxysmal cold hemoglobinuria. Patients diagnosed with CNS leukemia group A received MTX and those with anterior mediastinal mass group B were exposed to radiotherapy.

All patients immediately started the remission induction phase consisting of PRD VCR and asparaginase ASP. Erythrocyte rosette E-rosette formation assay has been successfully used to measure the CMI response produced due to different bacterial and viral vaccine. A new test termed the human allogeneic rosette test HART is reported for the detection of small amounts of erythrocyte autoantibodies.

If the rosette test is positive follow-up testing is done to quantitate the FMH eg a Kleihauer-Betke acid elution test or flow cytometry. Similarly for another rosette-mediating PfEMP1 variant IT4var60 site-directed mutagenesis studies of recombinant proteins showed that mutations that disrupt heparin binding are distinct from mutations that disrupt erythrocyte binding indicating that heparin-like molecules are not the main host rosetting receptor in this case Angeletti et al Reference Angeletti Sandalova. CD35 on uninfected erythrocytes.

Indeed a defunct laboratory test for rosette formation between patient erythrocytes and sheep monocytes the monocyte monolayer assay. In one prior report neutrophil-erythrocyte rosette formation was IgG-mediated but temperature-dependent 6 and in another the rosettes turned out to be an artifact of EDTA tube collection that was not reproducible with. An extensive infectious workup was negative including for syphilis.
