Companies usually start a recall weeks before the FDA classifies and publishes it; the gap above is that lag.

Reason for recall

After running the calibration curve, the recovery of the IgM kit control results decrease demonstrating a reduction in accuracy within the same day; control results may be out of range one day after running the assay calibration curve. Samples have been shown to be similarly affected.

Potency and specification recalls happen when a batch tests outside its approved limits for strength, purity or dissolution, which can mean the dose delivered is higher or lower than labelled.
