Rheumatology Profile - basic
Basic rheumatic tests are a laboratory panel used for the detection of inflammatory and autoimmune processes in the body and for early diagnosis of rheumatologic diseases. The panel helps assess inflammatory activity and detect connective tissue disorders even in early or mild stages.

- suspected rheumatoid arthritis
- persistent muscle or joint pain of unknown origin

Contraindications
There are no absolute contraindications. The test may be temporarily postponed in case of:
- acute infectious diseases
- severe exacerbation of chronic conditions (as decided by a physician)
Procedure
The test is performed on an outpatient basis and involves venous blood sampling. No special in-clinic preparation is required beyond standard blood test guidelines. Results are provided with medical interpretation.
