Interpretation
The difference between
two consecutive
measurements exceeds
4 SD. This may
indicate an inconsisten-
cy in your procedure or

SD range on the same
side of the mean. A
trend or shift is indica-
ted. Patient results
should be considered
unreliable until the
problem is remedied.
Ten consecutive
measurements are on
the same side of the
mean. A trend or shift
is indicated. Patient

sidered unreliable until
