A facility reported on 02sep2022 that a rule (user facility programmed logic) written caused a result to be released with the opposite value and comment than was expected.For example, a high microalbumin result was reported with a comment stating that the ratio could not be calculated because of a low result.The facility had written rules for test results above and below the analytical measurement range (amr) based upon the associated instrument error codes.According to the site, these rules functioned as intended prior to an instrument management server update.After the server update, the facility noted that the error code being used was being triggered for both high and low results, causing the rule to fire inappropriately.
