The average is 3,900-10,000. Lymphocytes are part of your immune system and are released if there is an infection that needs to be "fought" off. So therefore, if your count is higher than 10,000 you probably have some kind of infection that your body is fighting off. If it is excessively high (say the 100,000 range) it is possible that you may have leukemia (cancer of the white blood cells). I'm sure your doctor would have told you if it was extremely high - so most likely you just have an infection.
MCH (Mean Corpuscular Hemoglobin) Level:
The average is 32-36%. This measures the amount of hemoglobin in your blood (hemoglobin is what transports oxygen to your tissues). High levels are not a problem unless you have a certain genetic disorder which causes excessive amounts and too many red blood cells to be produced. You would already know if you had this problem. Most likely it is just the norm for you. Just to let you know, health care providers generally do not look at this number as any kind of indicator of anything - your hemoglobin and hematocrit are the numbers that are reviewed mostly when it comes to how your blood is functioning.
