The Differences Between Lupus and Rheumatoid Arthritis

RA includes both lab tests and imaging tests

Other tests that must be performed to diagnose RA include lab tests and imaging tests. If the lab tests show that the person has an antibody called anti-cyclic citrullinated peptide in their blood, it means that they could have RA. If these tests also find a protein called rheumatoid factor, there is at least an 80% chance that the patient is suffering from RA or another inflammatory disease.

Imaging tests can usually pinpoint damage to the person’s joints as a result of their condition, though this can only be seen in later stages of the disease.
