I am 27 years old. I am 5'5'' and weigh 130 lbs. I exercise regularly, eat relatively healthy and am a non-smoker. I don't have any medical issues and am not taking any medication, besides Yaz for birth control. I also take a number of vitamins, including a multi-vitamin, fish oil, folic acid, and calcium. I recently went to the doctor for a first appointment and had my blood and urine tested. I got the results back today, but am unsure how to interpret the results, besides the few that say "high" and "low". Those that are concerning to me are my neutrophil, which is low at 44, lymphocyte, which is high at 41, BUN, which is low at 5, AST, which is high at 59, and my cholesterol, which is an astounding 253. What do these numbers mean?
