Medical Device Recall: ACL TOP Coagulation Analyzers for Sample Misidentification
Instrumentation Laboratory is recalling ACL TOP coagulation analyzers due to potential sample misidentification that could result in incorrect test results and alter patient management decisions.
The agency’s classification
FDA (Devices): Class II
Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.
This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work
What this means for you
Our assessment, not the agency’s: severity 3/5 (High).
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 recall of an in vitro diagnostic device presenting a risk-of-harm hazard (sample misidentification leading to incorrect test results and altered patient management). No illnesses or injuries have been reported. Per the rubric, this meets the High (3) criterion for risk-of-harm products where injury has not yet been reported.
Plain-English summary
Instrumentation Laboratory is recalling certain models of the ACL TOP Family 50 Series in vitro diagnostic devices used for coagulation and hemostasis testing. The recalled models include the ACL TOP 550 CTS, ACL TOP 750 CTS, ACL TOP 350 CTS, ACL TOP 750, ACL TOP 750 LAS, and ACL TOP 970 CL, affecting approximately 2,068 kits distributed in the US and 6,270 units distributed outside the US.
The recall was initiated because sample misidentification could occur under specific conditions. When a sample is misidentified, the device may produce an incorrectly assigned test result, which could lead to altered patient management based on inaccurate coagulation or hemostasis findings.
The affected devices are distributed in the United States and internationally to Canada, Finland, Ireland, Lithuania, Malta, Qatar, and Sweden. Healthcare facilities and clinical laboratories using these devices should verify whether they possess affected units by model number and serial number range as detailed in the FDA recall notice.
Persons using these devices should contact Instrumentation Laboratory with questions about affected units. The FDA has provided updated information including affected serial number ranges for each model to assist in identification.
