Poor cfDNA Binding from Inadequate Incubation

Cell-free DNA yield is suboptimal despite proper bead addition and reagent preparation. A significant portion of DNA may remain unbound in the supernatant during the binding step.

DNA Loss from Bead Removal During Supernatant Transfer

Variable or reduced cfDNA yields across samples. Beads may be visible in wash supernatants or final eluate, or yield decreases progressively through the protocol.
