[127906981]
The customer contacted a siemens customer care center (ccc) to report that a discordant, falsely low d-dimer result was obtained on a patient sample on a sysmex ca-1500 system using the innovance d-dimer reagent. The customer properly filled the sample, it was not lipemic, icteric or hemolyzed. Siemens determined that quality controls (qcs) were within expected ranges on the day of event. Siemens determined that inadequate mixing, centrifuging or other sample handling issues could be the contributing factors to the discordant result. Inadequate sample mixing can lead to erroneous results due to micro clots or latent fibrin formation in the plasma portion of the sample. The customer did not report issues with any other assays on this instrument. The cause of the discordant, falsely low d-dimer result is unknown. The reagent is performing according to specifications. No further evaluation of the device is required.

[127906982]
A discordant, falsely low d-dimer result was obtained on a patient sample when the sample was diluted and repeated on a sysmex ca-1500 system, using the innovance d-dimer reagent. When the sample was initially run, a higher d-dimer result was obtained on the patient sample. The discordant result was reported to the physician(s) and recalled before the physician(s) saw the result. The sample was repeated multiple times on the same system under different sample ids, resulting higher. The repeat result of 4. 09 was reported, as the correct result, to the physician(s). There are no known reports of patient intervention or adverse health consequences due to the discordant, falsely low d-dimer result.
