A potential positive bias in quality control (QC) and patient sample results in three lots of the Dimension Tacrolimus (TAC) Flex reagent cartridge.

During 3D acquisitions, lighter and darker patient images may be captured, which may result in less accurate 3D reconstruction. The variation of brightness is a result of a constant unregulated medium dose and the angular change of patient diameter caused by rotational acquisition. This may result in unintentional low-dose radiation exposure to a patient.

During patient examinations, the system may sporadically display a major increase of the x-ray dose applied to the patient. Despite the reported dose showing significantly higher, the actual applied x-ray dose levels are in accordance with the system settings and imaging conditions, as well as the applicable regulatory requirements.

A potential for depressed results for Atellica CH A1c_E when processing Atellica CH RCRP on the same analyzer. Customers processing A1c_E and RCRP on separate analyzers are not impacted by the recall. The frequency and magnitude of the negative bias and imprecision increase over time and are not consistent with the assay Instructions For Use (IFU). When this issue is present, Quality Control (QC) results demonstrate a negative trend and increased imprecision. The clinical impact of a negative (A1c_E) bias may lead to a delay in diagnosis for diabetes or lead to less-than-optimal treatment for existing diabetes.

Falsely depressed UAlb patient results may occur. Affected samples with any urine albumin concentration above the UAlb measuring interval >40.0 mg/dL may report values between 6.2 mg/dL and 40.0 mg/dL.

Ortho images acquired with preset automatic horizontal flip are not flipped and when acquiring single images, there is the possibility that an image of a previous patient may be processed.

A potential issue associated with LUMINOS Lotus Max and Luminos dRF Max systems with software version VF11 with bucky wall stand for mobile detectors and without ceiling stand .When switching quickly between organ programs (OGPs) the collimation may be incorrect.

There were instances where the operator table was sold together with a bus-installation kit. The operator table is not intended and not released for bus installations as it was designed for stationary operation only.

The barcode orientation on affected devices causes incorrect scanning order of tubes within the allergen holder wedge. When using an IMMULITE 2000 / IMMULITE 2000 XPi instrument in combination with a Zebra barcode scanner, the instrument will not correctly recognize the position of tubes within the allergen holder wedge.

There is a potential for an ice blockage to form or currently exist within the primary and/or the auxiliary venting paths of the magnet helium containment venting system. In the event of a quench when both venting paths are blocked, helium gas may be unable to escape through the designed venting paths, leading to a pressure build-up within the helium containment system. This pressure build-up could ultimately rupture the helium containment system, potentially resulting in a helium leak into the scanning room.

The potential for falsely depressed Intact PTH patient results at the low end of the assay range, less than or equal to 50 pg/mL (less than or equal to 5.3 pmol/L), when using specific lots identified by the firm on the IMMULITE 2000/IMMULITE 2000 XPi systems. The bias is observed in both serum and plasma samples.

Two malfunctions posing potential risk to patients were identified with Siemens Ysio Max, AXIOM Luminos dRF Max, Uroskop Omnia Max, and Luminos Agile Max systems with a specific set of serial numbers that will cause lost images due to an automatic Radiology Information System (RIS) worklist update, thus causing examinations to be repeated. Image label may also be displayed incorrectly after images
