What do the green and red bars mean?
Much like the bars that indicate the level of "signal" on a modern cell phone, SignalRAYTM uses colored bars to indicate normal and abnormal signals.
Green symbolizes a normal signal.
Red symbolizes an abnormal signal.
The number of bars (2 or 4) represents the probability of normality/abnormality in each result.
