Dose Calibrator Software Bug May Cause Incorrect Isotope Measurements

AtomLab 500Plus Dose Calibrator software versions 2.0.00–2.0.08 contain a bug that fails to remove dial settings when deleting custom isotopes, potentially causing incorrect dose calibrations and misadministration.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This is an FDA Class II medical device recall involving a risk-of-harm product where incorrect dose calibration and misadministration of radioactive material could occur. No illnesses or injuries have been reported in the source text, placing this in the 'risk-of-harm products where injury has not yet been reported' category per the rubric.

Plain-English summary

The FDA is recalling AtomLab 500Plus Dose Calibrator software versions 2.0.00 through 2.0.08 (Model 086-332), manufactured by Biodex Medical Systems, Inc. Approximately 429 units have been distributed nationwide and internationally.

The software contains a defect in its custom isotope deletion function. When a user deletes a previously entered custom isotope, the software removes the isotope entry but fails to delete the associated dial setting. This leaves other custom isotopes in the system with incorrect dial settings, which can lead to incorrect dose measurements and potential misadministration of radioactive doses.

The affected software is used in nuclear medicine departments and facilities that rely on the AtomLab 500Plus Dose Calibrator to measure and calibrate radioactive isotope doses for patient administration.

Users of affected software versions should verify their version and contact Biodex Medical Systems, Inc. to determine if an update or patch is available to correct this defect.
