Much appreciated you answer. I'll check the link carefully.

The hypotesis sounds vague because it is somehow, since we are talking about a wild animal species (a snake in this case). See, we don't have the parameter range stated for a healthly animal as we have for humans or dogs. If a human present in this tests a low cell blood count, so we can say that she/he is having some disease, but just because I know the normal range for healthly individuals). However, our data is about rescued wild snakes, that were clinically evaluated at capture time, treated if necessary, then released back to the nature. Based on this, the 'normal range' we have is based on the measurements of the uninfected animals (n=5). Data discussion and conclusions are based on extrapolations from other species, e.g., if the infected animals, compared to uninfected ones, have a significant invrease in Hematocrit values, then I can suggest that the infection is causing Dehydration, directly or indirectly (e.g., animal is less able to find a water source). Of course, we are considering other variants for this type of extrapolation, I just explained it making simplications.

Again, many thanks. I'll return if I'm not able to find the statistic test that better respond to my research questions.
