PNH in AA and RA-MDS
Who to Test for PNH: Aplastic Anemia and RA-Myelodysplastic Syndrome
Aplastic Anemia (AA)
Approximately 70% of patients with AA have PNH cells*1:
- The number of PNH cells may increase rapidly and unpredictably over time2,3
- In patients with AA, the presence of PNH cells can positively impact response to immunosuppressive therapy1,4
Refractory Anemia Myelodysplastic Syndrome
Patients With Myelodysplastic Syndromes (MDS) Should Be Tested for PNH, as Recommended by NCCN Guidelines5

Select MDS subgroups are more likely to present with a PNH granulocyte clone1
- Interim analysis shows that 17% of patients with refractory anemia-MDS (RA-MDS) have PNH granulocyte clones, as identified by high-sensitivity flow cytometry*1
*0.01% PNH cell threshold.

The most sensitive and informative test to diagnose PNH.

Treatment options for PNH include monoclonal antibodies, bone marrow transplantation, and palliative therapies.
