NGS Familial HLH(Hemophagocytic Lymphohistiocytosis)

An NGS familial HLH test is advised by a doctor when HLH is diagnosed or suspected, especially in infants and young children, or with persistent fever, enlarged liver or spleen, low blood counts, and very high ferritin. It is also recommended for recurrent HLH, a family history of HLH, and screening potential sibling stem cell donors.

No special preparation or fasting is required for an NGS familial HLH test, as it analyzes DNA from a blood sample. Inform your doctor about any recent blood transfusion or stem cell transplant, as these can affect results. Share your family history, and consider genetic counseling before and after testing.

No, fasting is not required for an NGS familial HLH test. You can eat and drink normally before giving your sample, because the test analyzes your DNA, which is not affected by food or the time of day. Inform your doctor about any recent blood transfusion or stem cell transplant.
