Final answer:
The final diagnosis for Elisa's diabetes can be determined through tests such as the glucose tolerance test, insulin tolerance test, and glucagon tolerance test. However, confirmatory tests are necessary to ensure accurate results.
Step-by-step explanation:
The final diagnosis for Elisa's diabetes can be determined through several tests. One test is the glucose tolerance test (GTT), which confirms the presence of diabetes mellitus based on the observation of hyperglycemia. If GTT is positive, additional tests such as the Insulin Tolerance Test (ITT) and Glucagon Tolerance Test (GuTT) can be performed to determine whether the diabetes is insulin-dependent or independent. Another test, the glucagon tolerance test, helps detect the type of diabetes based on the presence or absence of hyperglycemia or changes in blood glucose levels.
However, it's important to note that the diagnosis of diabetes cannot be solely based on a single test. False-positive results can occur and cross-reactivity with other antibodies may lead to inaccurate diagnoses. Therefore, confirmatory tests, such as an immunoblot or nucleic acid antigen test, are typically conducted to confirm the diagnosis.
