A member asked:

Why do reference ranges of lab tests vary so much? not just a few points, but sometimes one source will give an upper limit 2-3 times that of another.

A doctor has provided 1 answer

Method and units: The reference ranges of lab results vary by the method of testing and units of reporting, in addition to other factors. If there is a specific test you have in mind, please provide specifics. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
