Hi Sue,
At diagnosis, my paraproteins were 31 at diagnosis, but they have been ‘undetectable’ for a long time now. However, paraprotein tests are not that sensitive.
A more sensitive tests relates to the type of MM. There are two types of “light chains” in everyone’s blood, called kappa and lambda. In myeloma, one of those two is – for most patients but not all – there in huge quantities.
In my case, for example, my kappa light chain was something like 4500 at diagnosis but now in remission it is around 30.That is a much more healthy level. The ratio of kappa to lambda is often used as a fairly sensitive test of myeloma levels.
