For example, measurement values for a serology test could be \"detected\", \"not detected\", \"inconclusive\", or \"test not done\". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code \"error\" could be used when the measurement was not completed. Because of these options, use-case agreements are required to interpret general observations for exceptional values.",
