Hi @patsing78, I don't think there is any clear cut test to diagnose RA. Here's some information I found on Mayo Clinic's site — "How can a doctor tell if you have rheumatoid arthritis? — 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." — Rheumatoid arthritis – Diagnosis and treatment: https://www.mayoclinic.org/diseases-conditions/rheumatoid-arthritis/diagnosis-treatment/drc-20353653

Here's some other information that speaks to the difficulty diagnosing RA.

You mentioned needing to know as it relates to further COVID vaccine injections. Here's an article from Mayo Clinic that discusses vaccines and their importance for those with RA, including the COVID vaccines.

Have you started any treatment or medications for RA?

John is correct there is no 100% definitive test for RA. However there are suggestive tests: RA factor Antinuclear antibodies, erythroycte sed rate, Compliment level. These lab values + the clinical presentation of the patient can give a relatively certain diagnosis.
