This Health Page has a list of blood tests that are often ordered.
Asking the first question about MS can soon turn into something that feels like you've opened Pandora's Box. There are so many variables with MS that it truly can be an overwhelming task.
Are you looking for testing info only or symptoms as well? There is an MS Tracker on MedHelp that could help some with monitoring symptoms. The last I looked at it there wasn't much about labs on there.
If you are finding interesting tidbits to investigate along the way your best bet might be to bookmark those discussions on your computer's favorite list. You could also copy and paste the URL address into Word (or whatever composition program your computer has) along with a very brief reminder of the subject it addresses. Otherwise - you probably have to have paper and pencil handy to take notes or write down topic "titles" to search for at a later time.
We might be able to offer more help if you can include more details of what you are trying to do. Just keep in mind that the info you collect is to help you get a clear idea of your personal health history. Seldom would you want to present everything you gather to a doctor! You'll need to gather and then condense. Sounds like soup! I must be hungry.....
I feel for you as the place you are navigating on this journey is extremely time consuming. Prepare for family/friends (maybe even doctors) to proclaim you are obsessed with "being sick". They can't understand. That's just how it is. But we do so don't hesitate to ask your questions.
