Event Description

There was an allegation of questionable results from coaguchek inrange meter compared to a laboratory result using the stago method.The meter result was 6.2 inr.The laboratory result was 4.7 inr.The results were taken less than 3 hours apart.The patient¿s therapeutic range is 2.5 - 3.5 inr.

Manufacturer Narrative

The meter serial number is (b)(6).The product has not been received at this time and is not expected to be returned.If the product is returned in the future, a follow-up report will be submitted.On a regular basis, coaguchek strips of lots currently valid in the market are tested as part of routine retention testing and results have passed the internal inspection.Section e3: occupation is patient/consumer.

Manufacturer Narrative

Section b6 was updated.Per product labeling: coaguchek uses human recombinant thromboplastin.Therefore, the comparability to other human recombinant thromboplastins is best, whereas higher deviations can occur with other thromboplastins.However, those higher differences between thromboplastins of different (rabbit, bovine-based) origins are not a coaguchek-specific issue.Similar differences can be observed when a human recombinant thromboplastin-based laboratory method is compared against several other (rabbit, bovine-based) laboratory methods.The investigation did not identify a product problem.
