Getting a Vectra DA Test

How can I get Vectra® DA?

Follow these simple steps to get your Vectra DA test:

  • Step 1: Your doctor orders a Vectra DA test for you.
  • Step 2: One tube of blood is collected at your doctor’s office, a local lab, or your home by a certified professional. Talk to your doctor about having it drawn at the same time as your other lab tests.
  • Step 3: Your blood sample is sent to our lab to conduct the Vectra DA test.
  • Step 4: Your doctor receives your Vectra DA test report in approximately 5-7 calendar days.
  • Step 5: Your doctor can share results from the Vectra DA test with you, helping you both assess your RA disease activity and facilitating a discussion about the treatment plan for your rheumatoid arthritis.

If you have an infection, such as the flu, or have had a recent vaccination, please let your doctor know before having blood drawn for your Vectra DA score.


How often should I get Vectra DA?

  • How often you get Vectra DA depends on your unique situation. You and your doctor should decide this together.
  • An initial Vectra DA score can be taken at any point following your diagnosis with rheumatoid arthritis. This initial test serves as your “baseline” score. Future scores can then be compared to determine any change in your RA disease activity.
  • Many doctors and patients assess rheumatoid arthritis disease activity with Vectra DA to obtain a baseline before making a change in treatment. Then a few months afterwards they can use Vectra DA again to measure the impact that changing treatment had on your RA disease activity.
  • Your doctor may ask you to have your blood drawn for the test a couple of weeks before your visit so you can discuss the results together.
