I asked because I added up the kappa and lambda values ​​and it was the same as the paraprotein value. There are laboratories that do not measure M protein. According to the answer, separate M protein values ​​should also be looked at.

No, M protein is not simply the sum of kappa and lambda paraproteins. M protein, also known as myeloma protein, monoclonal protein, M spike, or paraprotein, is produced by abnormal plasma cells. These proteins are monoclonal immunoglobulins, meaning they are identical antibodies produced by cloned abnormal plasma cells.

No, M protein is not simply the sum of kappa and lambda paraproteins. M protein, also known as myeloma protein, monoclonal protein, M spike, or paraprotein, is produced by abnormal plasma cells. These proteins are monoclonal immunoglobulins, meaning they are identical antibodies produced by cloned abnormal plasma cells.

Here are some key points about M protein:

- M Protein: Made by abnormal plasma cells.
- Types of Heavy Chains: IgG, IgA, IgM, IgD, and IgE.
- Diagnosis: High levels of M protein in blood or urine can indicate multiple myeloma or other plasma cell tumors.
- Tests: Serum protein electrophoresis (SPEP) measures M proteins in blood samples.
