Do you need to be fasting to check rheumatism?

Rheumatology usually requires fasting.

Many rheumatology-related tests require fasting. For example, some blood tests, such as erythrocyte sedimentation rate, C-reactive protein, rheumatoid factor, anti-cyclic citrulline antibody, etc., are important for the diagnosis of rheumatic diseases. If you eat, they may affect the accuracy of the test results, leading to misdiagnosis or missed diagnosis.

At the same time, fasting can more accurately reflect the basic state of the body. After eating, the body will produce a series of physiological changes, including fluctuations in blood sugar, lipids, etc., which may interfere with the judgment of rheumatology-related indicators.

In addition, some tests may also involve other tests such as liver function, which usually need to be performed on an empty stomach to ensure the reliability of the results.

Therefore, in order to ensure the quality and reliability of the test results, patients should be prepared strictly according to the requirements of the doctor.
