What is Vectra DA?

Vectra DA is an advanced blood test that measures RA disease activity. Vectra DA is intended for adults who have been diagnosed with RA (it does not diagnose RA). Vectra DA can be used to measure the level of disease activity at a specific point in time and with repeat measurements to track changes in disease activity over time. Vectra DA generates a single score between 1 and 100 (lower is better) that represents the level of RA disease activity. The score classifies RA into low, moderate, and high disease activity. For more information about Vectra DA, click here.

Where can I get help in interpreting my Vectra DA results?

Is myVectra related to MyRA™?

The myVectra portal was created by Crescendo Bioscience, the same developer of MyRA. Crescendo Bioscience created the MyRA app because we believe that tools like MyRA and our blood test to measure RA disease activity (VectraDA) are important to help enable more effective management of patients with RA.

What is an unadjusted Vectra DA score?

Your new Vectra DA score has been adjusted based on your age, gender and body fat, factors that may impact your Vectra DA score. Your unadjusted score does not include this adjustment, allowing for a comparison between your scores before and after December 4, 2017.

Can I compare my new Vectra DA score with my earlier scores?

Your new Vectra DA score has been adjusted based on your age, gender and body fat, and is not directly comparable to your scores before December 4, 2017. You may, however, compare your unadjusted score with scores prior to December 4, 2017.

Will my new Vectra DA score change very much?

Most patients will have similar scores for both their new Vectra DA score and their unadjusted score. If your score changes substantially, ask your doctor for help interpreting your new Vectra DA score.

Where can I find all of my Vectra DA scores on the new Test Report?

Page 4 includes your complete history of Vectra DA scores. Scores before December 4, 2017 will include the word "unadjusted" in parentheses next to the score. If you have or have had different healthcare professionals order Vectra DA for you, you may not see all of your Vectra DA scores on your Test Report; however, they can all be found in your myVectra patient portal.

What does the grey dotted line mean on page 1 of the new Test Report?

The grey dotted line marks the transition date when Vectra DA scores have been adjusted based on your age, gender and body fat. There is also an unadjusted Vectra DA score, allowing for a comparison between your scores before and after December 4, 2017.
