Example of array data, the SLE-key® rule-out test, that might be used to predict likelihood of an accurate systemic lupus erythematosus (SLE) diagnosis. Samples of known classification, SLE (blue) or non-SLE (red) are shown. An unknown sample in such a system would be tested to generate a score that in turn would be plotted on this curve (shown as “X”). Samples lower than a validated threshold (blue line) would have a low likelihood of an SLE diagnosis. Such data could be useful for triaging ANA-positive patients referred for rheumatology consultation (see references [62, 63])
