Recent recalls

• 2024-12-20Open, ClassifiedComponent design/selection

  Access hsTnI Reagent, REF B52699, Immunoassay Method, Troponin Subunit. For the quantitative determination of cardiac troponin I (cTnI) levels in human serum and plasma.

  Beckman Coulter, Inc. is recalling their Access hsTnI assay, a medical device by correction. The reason for the recall is: high troponin antigen (>55,000 pg/mL) can contaminate an analyzers probe and cause inter-assay carryover due to insufficient washing. The contamination can cause a falsely elevated Access hsTnI result in subsequent sample(s) which can impact patient care (potentially but not limited to unnecessary coronary imaging or diagnostic catheterization) if the result is near the medical decision points.

• 2023-07-07Open, ClassifiedNonconforming Material/Component

  Quidel Triage Cardiac Panel: REF: 97000HS, 97021HS (Troponin I), 97022HS (CK-MB and Troponin I), 97000HSEU, 97000HSEUJP, 97000HZ01, 97000QIL. Lots T13664 - T14045.

  Raw material issue may cause cardiac panel products to have an average of 30% troponin signal reduction across measurement range 0.05 ng/mL to 30 ng/mL, QC testing won't detect anomaly, so an alternate method is recommended, if unavailable, use recommendations to mitigate potential patient impact, which could be missed/delayed myocardial infarction diagnosis.

  Dimension LTNI -In vitro diagnostic test intended to quantitively measure cardiac troponin-I levels in human serum and heparinized plasma to aid in the diagnosis of myocardial infarction. Siemens Material Number (SMN)/REF (Catalog Number): 10444896/RF521

  Positive bias with Lithium Heparin plasma samples from individuals that are expected to be below the 99th percentile of 0.07 ng/mL [0.07 g/L], may lead to inappropriate intervention for myocardial infarction

  ADVIA Centaur Tni-Ultra Assay; SMN 10317708 - 100 tests and SMN 10317709 -500 tests Product Usage: For in vitro diagnostic use in the quantitative determination of cardiac troponin I (cTnl) in serum, heparinized plasma, or EDTA plasma using the ADVIA Centaur/ADVIA Centaur XP/ADVIA Centaur XPT/ADVIA Centaur CP systems. Cardiac troponin I determinations aid in the diagnosis of acute myocardial infarction and in the risk stratification of patients with non-ST segment elevation acute coronary syndromes with respect to relative risk of mortality, myocardial infarction (MI) or increased probability of ischemic events requiring urgent revascularization procedures.

  System-to-system bias between the Tni-Ultra assay on the ADVIA Centaur CP and ADVIA Centaur/ADVIA Centaur XP/ADVIA Centaur XPT systems.
