Most MS monitoring tells you what’s already happened. The Octave MSDA Test reveals disease activity in real time, so you and your care team can move forward with clarity and confidence.
“I wish I knew what was happening with my MS between appointments.”
MRIs and check-ups are helpful, but they only show part of the picture. Between visits, you are left wondering: Is my treatment working? Is something changing that I cannot see yet?
The Octave MSDA Test fills that gap. One blood test gives you a clear number that shows your disease activity right now, so you and your care team can make decisions based on data, not guesswork.
Ask your doctor if the Octave MSDA is right for you.
You track your steps, sleep, heart rate.
Numbers help you understand your body and stay on top of your health. Now you can do the same for your MS: your MSDA Score. One number that shows your MS activity, right now.
The Octave MSDA Test is the first and only blood test that measures 18 biomarkers designed specifically for MS.
Using machine learning, we combine this data with your medical history, your symptoms and millions of data points across our database to produce a single score that helps you and your care team have better conversations and make confident decisions about your treatment.
What it is
An easy blood test that looks at 18 different markers linked to MS activity. No other test goes this deep, this simply.
What it shows
Your score reflects disease activity happening right now, even changes that have not shown up on an MRI yet.
Why it helps
When you have a number to point to, conversations with your care team become clearer. You can track changes and talk about what they mean together.
Your score is most useful when tracked over time. One number is a starting point. Several numbers show how your therapeutic decisions effect your MS over time.
1 - 4.0
Low
Low disease activity
4.5 - 7
Moderate
4.5x greater risk of lesion development
7.5 - 10
High
21x greater risk of lesion development
Three simple steps, from talking with your provider to getting your results.
1
Talk to your provider
Your provider orders the MSDA Test for you.
2
Get your blood drawn
Visit any of 7,000+ Quest Diagnostics locations nationwide for a simple blood draw. Results are typically ready in 5-7 business days.
3
Results to your care team
Your care team receives your score, which you can discuss together at your next visit. Many patients repeat the test every 3-6 months to track activity over time.
All insurance plans are accepted, and most patients pay $100 or less for the MSDA Test. The Octave Cares financial assistance program (FAP) offers additional support — including prompt-pay discounts, interest-free payment plans, and a dedicated patient support team.

As a clinician, researcher, advocate and MS patient, I live the challenges of managing MS. The MSDA Test has given me invaluable insights that helped me navigate my own disease while also providing tremendous peace of mind. The Octave MSDA Test is the compass to care that we have been seeking.
The MRI tells you what happened. The MSDA Test tells you what to ask next. Now I test quarterly and bring the results to my neurologist. That's the tool I never had before.
My MRI scans have been stable for two years. My body tells a different story. The Octave MSDA Test helped bridge that gap - turning what I felt but couldn't prove into data I could bring to my neurologist.
