Spirometry is a lung function test that measures how much air you can inhale and exhale, and how quickly you can do it.

Wear loose clothing, avoid heavy meals or intense exercise before the test, and follow any specific instructions from your doctor.

No, spirometry is non-invasive and painless. You will be asked to breathe into a device, which may feel slightly uncomfortable but is not painful.

The test itself takes about 15-30 minutes. Results are usually available immediately or within a few hours.

The frequency depends on your health conditions and doctor’s recommendations. It may be performed regularly for ongoing monitoring or as needed for diagnosis.

The test helps diagnose rheumatoid arthritis by detecting specific antibodies associated with the condition.

A blood sample is collected and analyzed to measure the levels of anti-CCP antibodies.

No special preparation is required. You can eat and drink normally before the test.

Results are typically available within a few hours to 24 hours after the sample is processed.

Elevated levels suggest a higher likelihood of rheumatoid arthritis, but further clinical evaluation is needed for a definitive diagnosis.

Recovery time varies, but most patients stay in the hospital for a few days and gradually return to normal activities within weeks.
