Heater shaker module does not perform heating if the temperature is set below 40¿C for static incubation steps when running IVD protocol QIAamp¿ DSP DNA Mini Kit (cat. no. 61304), Protocol: Isolation of genomic DNA from Gram-positive bacteria (Script filename: Kt_name_Bacteria (Gram+) or rY'east_Enzymatic Lysis_ V2) which could potentially cause delayed or erroneous results depending on the downstream assay.
Class I - Dangerous
Insufficient welding leads to the heater cable becoming brittle and present with an error: ERROR 3481 HEATER UNABLE TO REACH TEMPERATURE; the instrument may stop, and the sample being processed will be lost
Class I - Dangerous
Faulty cartridges in the lot could result in false test results.
Class I - Dangerous
During the "Load tip racks and enzymes" step of the run set-up, the info screen indicates "minimal volume to be loaded", but the indicated volume is instead the exact volume that should be loaded. Misunderstanding the guidance may lead to over diluted, under diluted, or improperly lysed sample, which in turn could lead to false negative or false positive results.
Class I - Dangerous
Increased occurrence rate of false positive results, lead to a false positive sample result that could subsequently be incorrectly reported from the laboratory. A false positive result could lead to the risk of the patient being exposed to an inappropriate or suboptimal anti-cancer treatment and/or unnecessarily experiencing side effects
Class I - Dangerous
Increased occurrence rate of false positive results, lead to a false positive sample result that could subsequently be incorrectly reported from the laboratory. A false positive result could lead to the risk of the patient being exposed to an inappropriate or suboptimal anti-cancer treatment and/or unnecessarily experiencing side effects

A false positive result could lead to the risk of the patient being exposed to an inappropriate or suboptimal anti-cancer treatment and/or unnecessarily experiencing side effects
Class I - Dangerous
False positive or false negative G12C (12CYS) mutation result for the KRAS Mutation Status resulting from Flags/Warnings may invalidate the result for one or more individual mutation target of the kit.
Class I - Dangerous
False positive or false negative G12C (12CYS) mutation result for the KRAS Mutation Status resulting from Flags/Warnings may invalidate the result for one or more individual mutation target of the kit.
Class I - Dangerous
The firm identified sixteen (16) faulty cartridges in LOT 210209, which contain incorrect primer-probe mixes in the reaction chambers. If an affected cartridge is used, false-negative, false-positive, or both false-negative and false-positive results could occur.
Class I - Dangerous
QIAGEN has become aware of the potential for false positive results to occur with some patient samples.
Kit may generate false Q546R mutation positive results caused by nonspecific molecular interactions within the Q546R higher than previously observed and described within the Instructions For Use.
There is an increased rate of potential false positive results for the Influenza A (no subtype) target, which may lead to 1) inappropriate antiviral use, 2) erroneous or delayed differential diagnosis and missing of an alternative diagnosis.
Class I - Dangerous
There is a risk for a false mutation positive result in rare cases resulting from a fluorescence artefact. In these rare cases, the controls pass correctly, while a fluorescence artefact in the mutation assay causes an incorrect valid mutation positive result.
Class I - Dangerous
An image on the associated polybag contains an incorrect rinse time of 30 (thirty seconds). The correct rinse time is 1 (one) minute.
Class I - Dangerous
When using the Rotor-Gene Q with Software version 2.3.4 completing a LIMs export, the .csv file reports the calculated concentration result value as a logarithmic value, and could lead to a false negative result, which could lead to serious medical consequences such as the suspension or non-initiation of treatment
QIAsymphony software version 5.0.3 - Software issue incorreclty assigns the 2D bar code eluate ID to the sample within the results file. If 2D bar code eluate IDs are not checked against the sample ID prior to downstream application the incorrect tube may be selected and it could have the potential to lead to delayed results or incorrect patient reporting
Kit lots contain a small percentage of damaged Filter-Tips that are leaking when being used with the QIAsymphony SP/AS Instruments (REF 9001297 and 9001301)
The deparaffinization solution contains a contaminant, which leads to reduced lysis efficiency of the affected lot, resulting in significantly reduced yields and less sensitive downstream applications.
An issue with the power branching printed circuit board (PCB) on the instrument that has the potential to trigger a heater malfunction was discovered. If this failure were to occur, nucleic acid extractions could be compromised and extractions need to be repeated. This could cause a delay in obtaining results from downstream applications.
Potential for control line not appearing on the test strip
Class I - Dangerous
Potential for obtaining a false positive result due to the possibility of endotoxin presence.
