CBC shows slightly low hemoglobin , low MCV but high RBC hgb 12.1 (13.2-17.1), mcv 64.4 (80-100), mch 20.1 (27-33), rbc 6.03 (4.2-5.8) Not necessarily looking for a diagnosis given the lack of detail but, rather, an explanation on how you can have lots of red blood cells but low hemoglobin -- what is the process there? Thank you!
