One key is to look for L (low) and H (high) labels next to the various blood counts.
A blood count report typically shows a "normal range" for each count, and L or H indicate that the test result was lower than the normal range or higher than the normal range. This lets you see at a glance which counts are too low or too high, and you can then look at the range to see just how far off the number is.
Each treatment center has its own idea of what "normal" means, so what's "barely within range" on one lab's report might be "slightly out of range" on another lab's report.
