Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Western Blot is a more sensitive technique for detecting HIV antibodies than enzyme immunoassay?

No. Western Blot is historically used as a confirmatory test rather than a primary screening tool, and modern evidence shows it is less sensitive than enzyme immunoassays or nucleic acid testing, frequently resulting in indeterminate findings during acute infection.

The analysis

The claim states that Western Blot is more sensitive for detecting HIV antibodies than enzyme immunoassay. Standard medical knowledge and the provided literature (such as papers 0, 4, and 9) establish that enzyme immunoassays are used as sensitive screening tests, whereas Western blots are confirmatory tests that can be less sensitive and frequently yield indeterminate results during early seroconversion.
