Imaging Tests Magnetic resonance imaging (MRI) and ultrasound may help diagnose rheumatoid arthritis in the early stages of the disease. In addition, these imaging tests can help evaluate the amount of damage in the joints and the severity of the disease.
No blood test can definitively prove or rule out a diagnosis of rheumatoid arthritis, but several tests can show indications of the condition. Some of the main blood tests used include: erythrocyte sedimentation rate (ESR) – which can help assess levels of inflammation in the body.
RA is symmetrical, where a patient feels symptoms in the same spot on both sides of the body, often in the joints in the feet and hands. Osteoarthritis, in contrast, begins in an isolated joint, often in the knee, fingers, hands, spine and hips. While both sides may hurt, one side is more painful.
The main clinically useful biologic markers in patients with RA include rheumatoid factors (RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP).
Antibodies to citrullinated protein antigens (ACPAs) are highly specific for rheumatoid arthritis (RA) and are useful in the diagnosis of RA as well as the prediction of the course and outcomes of disease.

Lupus and Scleroderma
The autoimmune diseases systemic lupus erythematosus and scleroderma are two separate conditions but often present with joint involvement that mimics rheumatoid arthritis. One key difference between arthritis and lupus or scleroderma is the source of joint pain and deformity.
Rheumatoid arthritis can be difficult to diagnose in its early stages because the early signs and symptoms mimic those of many other diseases. There is no one blood test or physical finding to confirm the diagnosis. During the physical exam, your doctor will check your joints for swelling, redness and warmth.
The symptoms of rheumatoid arthritis often develop gradually over several weeks, but some cases can progress quickly over a number of days. The symptoms vary from person to person. They can come and go, and may change over time.
Stage I: Synovitis
During stage I, you may start having mild symptoms, including joint pain and joint stiffness. Most commonly, this affects the hands and fingers, as well as the ankles and knees. The immune system has begun attacking the joint tissue, causing the synovial membrane to swell and become inflamed.
Methotrexate is usually the first medicine given for rheumatoid arthritis, often with another DMARD and a short course of steroids (corticosteroids) to relieve any pain. These may be combined with biological treatments.
At-home rheumatoid factor (RF) testing: At-home rheumatoid factor testing detects levels of rheumatoid factor in the blood. Testing kits allow patients to obtain a sample of blood using a finger stick. Once a sample of blood is collected in a test vial, it's sent to a laboratory for analysis.
You can get rheumatoid arthritis (RA) at any age, but it's most likely to show up between ages 30 and 50. When it starts between ages 60 and 65, it's called elderly-onset RA or late-onset RA. Elderly-onset RA is different from RA that starts in earlier years.
People with rheumatoid arthritis typically have several permanently inflamed joints. The inflammation inside the body can lead to general physical weakness, drowsiness and exhaustion. This feeling of extreme tiredness is also called "fatigue." Some people find this to be the worst symptom of the disease.
The symptoms of rheumatoid arthritis often develop gradually over several weeks, but some cases can progress quickly over a number of days. The symptoms vary from person to person. They may come and go, or change over time. You may experience flares when your condition deteriorates and your symptoms become worse.
In MS, attacks on the myelin sheath cause damage that disrupts brain and spinal cord connections and leads to a wide range of symptoms. On the other hand, RA is characterized by joint pain, swelling, and stiffness. RA can also affect the body's organs, including the skin, eyes, heart, and lungs.
Rheumatoid arthritis (RA) is recognized as the most disabling type of arthritis.
For decades, X-rays were used to help detect rheumatoid arthritis (RA) and monitor for worsening bone damage. In the early stages of RA, however, X-rays may appear normal although the disease is active, making the films useful as a baseline but not much help in getting a timely diagnosis and treatment.
No single blood test can reliably diagnose RA. Some healthy people test positive for anti-CCPs, while others who have RA have negative test results. Blood tests are just one of several factors, including a medical history, physical exam and X-rays, that help doctors diagnose the disease.
