Your WBC count looks fine. Nothing to suggest a bacterial infection there. Your hematocrit is on the higher side, but entirely within the normal limits at my hospital (normal hematocrit 41-53). In people who have elevated 'crits, there are often very normal reasons for them to be elevated. For example, smokers often have elevated hematocrits. Without geeking out too much, your red blood cells (RBC's) carry oxygen. We usually measure RBC's kind of indirectly by measuring hematocrit and hemoglobin. If you are a smoker, you will often be replacing some of that oxygen that you inhale with tobacco smoke. Your body compensates by increasing the number of RBC's available to carry oxygen.
Looking at your lab panel you've listed, it doesn't really support you being significantly dehydrated. Your chemistry panel is much more useful in helping determine if someone is dehydrated.
If you have been having a lot of diarrhea and vomiting, you can get dehydrated, but it doesn't sound like you've had much of that. Looking at the numbers you've posted, I really don't see too much that jumps out at me as being abnormal. BUT, if you are feeling unwell, go to a doctor!
