Why did my doctor order the Vectra DA test for me?
RA is an autoimmune disease that can affect people differently. People with RA often experience varying degrees of pain, inflammation, and rates of joint damage. Sometimes, your RA may be active even though you are feeling well and no signs of problems are readily apparent. To detect what’s going on underneath the surface, Vectra DA measures proteins involved in the processes that cause and control RA in your body, so you and your doctor get a more detailed, comprehensive picture of your disease.
How often should I get the Vectra DA test?
Vectra DA may be considered any time your doctor determines that it is medically necessary to assess disease activity. The frequency of the assessment may vary for each patient, and your doctor will suggest the testing schedule that’s right for you.
How is Vectra DA different from other blood tests used to monitor RA?
Other lab tests typically measure inflammation indirectly (like ESR) or measure 1 inflammatory protein (like CRP). The Vectra DA test is different - it measures 12 key proteins that represent multiple biological pathways and combines them into a single score (between 1 and 100) that classifies your RA into low, moderate, or high disease activity. This gives you and your doctor a more comprehensive understanding of the current state of your RA – all with a single number that can be tracked over time. Vectra DA was studied in patients with RA just like you so it is designed specifically for RA.
How much blood is required for a Vectra DA test?
When your doctor orders Vectra DA, a single test tube of blood will be collected in a laboratory either on-site at your doctor’s office or at a local lab. The blood sample will then be shipped to Crescendo for specialized processing in our lab.
What does it mean when my Vectra DA score doesn’t match my symptoms?
RA can sometimes be active even though you are feeling well and no signs of problems are readily apparent. You may also have some symptoms that are not driven by your RA inflammation. Certain medications, infections, or surgical procedures could also affect the biomarkers contained in Vectra DA. Your doctor will evaluate your Vectra DA score and medical history along with his/her overall clinical assessment to determine what is right for you.
How much will Vectra DA cost me?
Our goal is to ensure that cost is not a barrier for anyone with RA who wants a Vectra DA test. The amount for which you are responsible will vary depending on your health care plan and your ability to pay. Crescendo Bioscience offers comprehensive reimbursement services through its Crescendo Access and Reimbursement Essentials (CARE) program.
We will provide testing at no cost for RA patients who: (1) are US citizens or legal residents, (2) have a diagnosis of RA, (3) are uninsured or don’t have insurance that covers the test, and (4) meet household income requirements.
You can be prequalified over the phone by calling our CARE program reimbursement specialists at 1-877-RHEUMDX (1-877-743-8639) or you can download an application here

Can Vectra DA confirm my RA diagnosis?
Vectra DA is for people who have already been diagnosed with RA. Vectra DA assists your doctor’s judgment to help you manage your RA. It can provide a look at your disease at a single point in time and can also be used to track your disease activity over time, so you can assess your RA management plan. Vectra DA is not meant to diagnose RA.
Who can benefit from Vectra DA?
Vectra DA can be used in any adult who has been diagnosed with RA. The test is not intended to diagnose RA.
How is Vectra DA different from CRP testing?
Vectra DA simultaneously measures 12 biomarkers that are associated with RA disease activity and combines them into a single score (between 1 and 100) that classifies your RA into low, moderate, or high disease activity. In contrast, the CRP lab test assesses only a single biomarker.
How do I get the results of my Vectra DA test?
Your doctor will receive the Vectra DA test report approximately 5-7 calendar days after shipping your blood sample to Crescendo Bioscience. You can contact your doctor regarding your test report and discuss the results in the context of your other clinical assessments, or you can contact our customer service team at 1-877-743-8639 to obtain a copy of your test report.
The Vectra DA test does not replace your doctor's evaluation and is meant to be used along with your other clinical assessments.
