Stool antigen tests play a critical role in the nursing field for several reasons: - Quick Diagnosis: These tests provide rapid results, often within hours, allowing for timely diagnosis and treatment. - Non-Invasive: Unlike endoscopic procedures or blood tests, stool antigen tests are non-invasive, reducing patient discomfort and risk. - Accuracy: These tests are highly sensitive and specific, making them reliable for detecting various pathogens. - Monitoring Treatment: Nurses can use these tests to monitor the effectiveness of ongoing treatment, especially for infections like H. pylori.
