What is the expected DNA yield from 2.5 ml of blood when using the QIAsymphony, QIAcube, and salting-out precipitation method?

Yield of genomic DNA varies depending on the white blood cell count of the patient blood sample, the extraction method, and the elution volume. However, DNA yield typically ranges between 16–135 µg/ml whole blood. Specifically, DNA yields from magnetic bead-based extraction on the QIAsymphony ranges between 16.9–51.7 µg/ml whole blood, from silica membrane-based extraction on the QIAcube 17.1–45.8 µg/ml whole blood, and from salting-out precipitation 4.9–53.7 µg/ml whole blood.
