What's this test for?

This test is ideal if you're experiencing persistent joint pain, morning stiffness that lasts more than 30 minutes, or swelling in your hands, wrists, or other joints. It helps identify rheumatoid arthritis, an autoimmune condition where your immune system mistakenly attacks your joints, causing inflammation and damage. Many people use this test when they suspect their symptoms might be RA but want concrete answers before starting treatment.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your inflammation markers and antibody levels mean for your joint health. These notes include personalized recommendations like anti-inflammatory dietary changes, supplement suggestions for joint support, or whether you should follow up with a rheumatologist. You'll also get the standard lab report and can track your inflammation markers over time using our trends feature to see how your interventions are working.

What's included in this test?

This panel measures Rheumatoid Factor (RF), ANA Screen (Antinuclear Antibodies), C-Reactive Protein (CRP), Sedimentation Rate, Complete Blood Count (CBC with Differential), and Comprehensive Metabolic Panel (CMP including liver and kidney function tests). This comprehensive panel measures Rheumatoid Factor (RF) and ANA antibodies to detect autoimmune activity that attacks your joints. It checks inflammatory markers like CRP and sedimentation rate to assess how much inflammation is present in your body. The Complete Blood Count and Metabolic Panel provide a complete picture of your overall health, kidney function, and liver function, which is important for monitoring RA and potential treatment side effects.

How should I prepare for this test?

You should fast for 12 hours before your blood draw, which means no food or beverages except water during that time. This ensures accurate results for the metabolic markers included in the panel. Estimated turnaround for results is 4 business days, though if confirmation testing is required, it may take a bit longer.

When will I get my results?

Results are typically available within 4 business days after your blood sample is collected. If any of the tests require confirmation or additional analysis, the turnaround time may be extended slightly. You'll be notified as soon as your results are ready to view in your account.

Who should consider getting this test?

This test is important for anyone experiencing unexplained joint pain, stiffness, or swelling, especially if it affects both sides of the body symmetrically. It's also valuable for people with a family history of rheumatoid arthritis or other autoimmune diseases, those who notice their symptoms are worse in the morning, or anyone whose doctor suspects RA based on physical examination.

What symptoms indicate I may need this test?

Common symptoms include persistent joint pain and swelling, especially in the hands, wrists, knees, or feet. Morning stiffness lasting 30 minutes or longer, fatigue that doesn't improve with rest, and symmetrical joint involvement (affecting the same joints on both sides of your body) are key indicators. Some people also experience low-grade fever, loss of appetite, or firm lumps under the skin near affected joints.

How can I naturally support joint health with rheumatoid arthritis?

Focus on an anti-inflammatory diet rich in omega-3 fatty acids from fish, walnuts, and flaxseeds, and include plenty of colorful fruits and vegetables. Regular low-impact exercise like swimming, walking, or yoga helps maintain joint flexibility and reduces stiffness. Getting adequate sleep, managing stress, and maintaining a healthy weight can significantly reduce inflammation and joint pain.

What is Rheumatoid Factor and why does it matter?

Rheumatoid Factor (RF) is an antibody produced by your immune system that can attack healthy joint tissue. About 70-80% of people with rheumatoid arthritis test positive for RF, making it a key diagnostic marker. However, some people with RA test negative, and some healthy people test positive, which is why doctors use it alongside other tests and clinical symptoms to make a diagnosis.

What does a high sedimentation rate mean?

A high sedimentation rate (sed rate) indicates inflammation somewhere in your body. In the context of rheumatoid arthritis, it shows that your immune system is actively causing inflammation in your joints or other tissues. Tracking this marker over time helps determine if RA is getting worse, improving, or how well treatments are controlling the inflammation.
