DEVICES AND METHODS TO DETERMINE WHETHER TO CALIBRATE A LABORATORY ANALYZER

摘要

Generally discussed herein are systems, apparatuses, and methods that relate to detecting an error in a laboratory analyzer. A device may include an average of deltas (AoD) module to receive pairs of consecutive measurement values of an analyte of one or more patients, each pair of consecutive measurement values including a first measurement of an analyte obtained from a patient of the one or more patient at a first time and a second measurement of an analyte obtained from the patient at a second time after the first time, determine a time delta between each pair of consecutive measurement values, determine whether the time delta is within a specified time window, determine a measurement value deltas between each pair of consecutive measurement values that includes a time delta with the specified time window, and determine an AoD using the determined measurement value deltas.

1. A method comprising:
determining a time delta between consecutive measurements of an analyte made on a patient using a laboratory analyzer; determining whether the time delta is within a specified time window; determining a measurement value delta between the first and second measurements if the time delta is within the specified window; calculating an average of deltas, the average of deltas including a measurement value delta between the consecutive measurements; determining whether the average of deltas is within a specified range of acceptable average of delta values; and issuing an alert if the average of deltas is not within the specified range of acceptable average of delta values.
