The (b)(6) health services uses specimen gate® laboratory (sgl), a software product provided by (b)(4).Sgl contains a database and possesses functionality which enables laboratories to track specimens as they navigate through the laboratory with audit trails, security, and handling logic based on customer rules for qc, result-to-reference range analysis, result flagging, etc.Sgl is a class i medical device intended to store, retrieve, and process the data.The (b)(6) health services newborn screening laboratory uses the (b)(4) specimen gate® laboratory (sgl), version 2015.When the software is deployed, configurable settings are programmed based on the customer preferences.For instance, each laboratory enters their specific population based reference ranges that are used to evaluate if a patient's test results are normal, below or above the reference range and require further action such as repeat testing.In this incident, the results of a newborn dried blood spot sample tested on (b)(6) 2015 were determined as normal for citrulline analysis although the tested value for the analyte was above the established reference range cut-off.The cut-off was incorrect within the software due to a transposition of numbers upon entry.The cut-off was entered as 150 instead of the intended 105.This error was discovered before the patient results were reported.Due to the elevated citrulline measurement and per routine protocol, the sample was retested on (b)(6) 2015 and an accurate report was released on (b)(6) 2015.There was no impact to patient welfare and no delay in reporting.
