A change of 0.6 G/dl (either up or down) is totally insignificant, and should be regarded as within the bounds of what we all seek, ie STABILITY. CAA limits are very sensibly placed at 13 - 18 G/dl and
99 % of healthy adult males will fall in this range. For obvious enough reasons, some females will have slightly lower levels.
What we measure is a concentration, not an absolute amount of haemoglobin, so the figure can even be affected by how well or how poorly hydrated you are at the time of the finger prick !
