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

Reason for recall

Bilateral L-Dex assessment software does not have the same level of sensitivity to help detect early signs of lymphedema as the unilateral arm L-Dex assessment, which could result in under-recognition of early lymphedema, which could result in delay in early intervention, and more aggressive intervention.

Device recalls are issued when a component, software or design fault could cause the device to fail or give wrong readings. Many are corrections applied in the field rather than physical returns.
