Hi Kaayla,
Welcome to the forum and sorry to hear about your situation.
Jim asked some good questions.
That is indeed a low hemoglobin level and that can sometimes be a symptom of multiple myeloma. In any case, I'm glad you are seeing a hematologist tomorrow. Has your anemia been explained earlier by any other medical conditions?
An M-spike by itself is not a good marker for determining whether you have multiple myeloma and what stage of myeloma you might have (which is why Jim asked about all these other markers). In fact, there are several different "flavors" of multiple myeloma and you can have myeloma and not even have an M-spike. Your hematologist will know which tests to run to narrow down the possibilities.
Before you see the hematologist, I might suggest reading through
this handbook so that you have a better idea of what the doc might be discussing with you with respect to the possibility of multiple myeloma.
If the hematologist suspects multiple myeloma, he/she will likely order most of the tests outlined in the Laboratory Tests section of
this pdf.
When you see the hematologist, I might suggest recording the appointment on a phone, or taking lots of notes or inviting a friend to listen to what he/she has to say. The first appointment or two with a hematologist can often overload a person with information that is hard to remember later.
Let us know how things turn out and good luck.
