Additional Manufacturer Narrative

Siemens has completed the investigation.The definitive root-cause for the low thb could not be determined.Based on the investigation this rp500 system appeared stable and functioning as expected.Data did not suggest anything unusual about the co-ox behavior of this patient or that hemodialysis impacted the thb result.The reported thb results appear valid.For an accurate measurement of thb, thorough mixing and multi-directional rotating of the red blood cells immediately before analysis is required.This is particularly important for blood samples of lower hematocrit (red blood cells) as the cells more quickly settle out, falling out of homogeneity.Pre-analytical sample condition(s) is most likely a primary contributor to the observed discordant thb values.Cause of this event is unknown.
