'Analyzes' is the third person conjugation in the present simple of the verb 'to analyze' (or 'analyse' as we Brits write it). It is not a plural noun. So: 'the scientist analyzes the data'. The plural of the noun 'analysis' is 'analyses'. Example: 'she reads the analyses'.
This doesn't make sense. As a Romanian speaker who wants to practice (I don't speak Romanian on a regular basis) I know this sentence to mean "what di my tests show?" as this is what we'd ask the doctor (among others) every time :) also the word analyzes is not a pkural noun...
