X-Linked Chronic Granulomatous Disease: Initial Presentation with Intracranial Hemorrhage from Vitamin K Deficiency in Infant

Figure 2

The DHR assay of the patient showed complete absence of DHR shift after granulocyte stimulation. The SI was 1.21 which was compatible with XL-CGD. The DHR assay of the patient’s mother showed bimodal distribution which was compatible with the XL-CGD carrier. The stimulation index (SI) was calculated by dividing the mean channel of fluorescence intensity in the stimulated cell over the mean channel of fluorescence intensity in the unstimulated cell.
