Figure 5. Low interference in biological samples.
To determine whether PEA was affected by interference, three known interfering substances were spiked in plasma and measured by 96-plex PEA. No interference was seen with plasma containing (A) bilirubin or (B) intralipid, while a few assays showed increased signal in plasma containing (C) hemolysate, most likely due to actual analytes leaking out from the disrupted blood cells.
