Where is the M-spike in my lab results?

by Shari on Fri May 01, 2015 1:55 pm

I have been recently diagnosed with multiple myeloma and find myself easily confused with the terminology of the disease. So I was wondering if anyone can help me make sense of my numbers?

My family and I have set up a schedule that if everything goes as planned or scheduled, I should be having a plasma transplant around July of 2015. How do I read or recognize a "M-spike"?

Shari,

Your M-spike isn't included in these reports. You need to look at your Serum Protein Electrophoresis (SPEP) test results to get that value. It may be listed in a separate notation on the SPEP report as an "M-spike", "paraprotein" "monoclonal protein", or "M-protein" value (they are all the same thing). Alternatively, it may be listed as a value labelled as "Abnormal Protein Band 1" (or something similar to that) in the SPEP report.

Hi again Mulitbilly, I just cut and pasted my test result numbers and I see both M-protein and abnormal protein elect...... so which do I read to know if I have a M-spike (what does the M-spike mean anyway)?? Really curious to make sense of this multiple myeloma (multiple myeloma).
TOTAL PROTEIN 6.0 - 8.0 g/dL 8.3
ALBUMIN 3.40 - 4.90 g/dL 3.45
ALPHA-1-GLOBULIN, ELECTROPHORESIS 0.17 - 0.50 g/dL 0.27
ALPHA-2-GLOBULIN, ELECTROPHORESIS 0.55 - 1.00 g/dL 0.58
BETA GLOBULIN, ELECTROPHORESIS 0.65 - 1.10 g/dL 3.70
GAMMA GLOBULIN, ELECTROPHORESIS 0.70 - 1.60 g/dL 0.30
M-PROTEIN, SERUM 0.00 - 0.00 g/dL 2.77
PROTEIN ELECTROPHORESIS RESULT, SERUM Abnormal

Your M-spike = the M-protein level of 2.77 g/dL.

If you were able to look at the actual graph that the labs use to detect and measure an M-spike, you would find that there is actually a "spike" in your SPEP graph that is caused by the monoclonal (unhealthy/cancerous) immunoglobulin in your blood. Hence the name "M-spike" ("M" = monoclonal)

See this link to see what this spike looks like.

http://www.myelomapennstate.net/Contents/12b-Lab.htm

In your case, this unhealthy/monoclonal immmunoglobulin is specifically IgA immmunoglobulin (immunoglobulin is just a fancy word for a kind on antibody in your blood).

Remember that your IgA reading was high (3600 mg/dL) on your other test results, right? This is because you have both normal/healthy IgA immunoglobulins in your blood PLUS unhealthy/monoclonal versions of your IgA due to your multiple myeloma. The IgA value in your lab result includes both the healthy and monoclonal versions of the IgA levels and that is why your IgA level is elevated so much.

Not to confuse matters too much, but measuring IgA-type M-spikes with an SPEP has its challenges and is often inaccurate...so your doctor will clearly be looking at all of your lab values to help track the disease.

Hope this helps.

I have a copy of my hus­band's SPEP and his IgG is normal, his M is < 4, but his IgA is the one elevated. Thus our PCP told us it looks like IgA myeloma, but I do not see an actual number referring to an M spike on the report. There is no graph included. Thanks.
