How to perform laboratory testing for pericardial effusion

The examination of pericardial effusion mainly involves a series of diagnostic methods to determine the nature and cause of the effusion. 1. Echocardiography is a commonly used method for diagnosing pericardial effusion, enabling accurate assessment of the volume of effusion and observation of its dynamic changes. 2. Pericardial puncture is an important diagnostic technique that not only confirms the presence of effusion but also allows for biochemical, microbiological, and cytological analysis of the collected fluid sample, thereby determining the nature and potential cause of the effusion. 3. X-ray imaging and electrocardiography (ECG) can also provide supportive information for the diagnosis of pericardial effusion. 4. Routine tests such as complete blood count (CBC), urinalysis, erythrocyte sedimentation rate (ESR), and blood biochemistry are helpful in assessing the patient's general condition and provide a basis for formulating treatment plans. The examination of pericardial effusion is a comprehensive process that requires the integration of multiple diagnostic methods.
