Which outcome should a nurse anticipate will happen when a patient's first ELISA result is positive?

A. Another blood sample must be obtained for testing: To ensure accuracy and rule out laboratory error or false positives, the ELISA test is typically repeated using the same blood sample (or a new one depending on facility protocol) before moving to confirmatory testing. B. A Western blot test is performed on the same sample: Standard protocol for HIV testing dictates that a positive ELISA (screening) must be confirmed with a more specific test, like the Western Blot or IFA, to verify the diagnosis. C. The test is repeated in 6 to 8 months: This would delay diagnosis unnecessarily. While the "window period" is a factor in initial negative tests, a positive result requires immediate follow-up confirmation. D. The diagnosis of AIDS is confirmed: A positive ELISA only indicates the presence of HIV antibodies; it does not diagnose AIDS, which is the advanced stage of HIV infection.
