What tests are included in a Basic Diagnostic Test for assessing gastrointestinal health?

A Basic Diagnostic Test for assessing gastrointestinal health typically includes evaluations of blood, urine, and stool samples. Blood tests are essential in identifying various conditions, such as infections, liver function, and nutritional deficiencies. Urine tests can provide insights into kidney function and metabolic disorders, while stool tests are crucial for diagnosing infections, gastrointestinal bleeding, and other digestive issues. This comprehensive approach helps healthcare professionals paint a clearer picture of a patient's gastrointestinal health and guide further investigations if necessary.

In contrast, the other options involve combinations of tests that may not cover the same foundational aspects of gastrointestinal assessment. For instance, while x-rays and CT scans are valuable imaging techniques, they are not part of a basic diagnostic workup but serve more specialized purposes. Similarly, ultrasound can provide useful insights but does not contribute directly to the standard evaluation through stool and urine analysis.
