Hi Lamilu,
You know since I have MDS I don't know much about AA but here you will get the normal counts. Different labs can have a little different reference values but they are always written on the lablists:
http://www.lymphomation.org/CBC-blood-counts.htm
As you have understood hemoglobin, white blood cells (specially the neutrophils) and platelets are the most important counts.
A hemoglobin of 91 (or 9.1) is quite good - many patients manage well with that but your mother has heart problems that make her feel the low hemoglobin.
When her neutrophils are 0.4 she can easily get infections - if they have done the examinations like BMB she should at once have Neupogen or a similar drug for her white blood cells.
It is a problem with platelet transfusions because they never last long - hopefully the platelets will increase when she receives steroids.
Kind regards
