We most often judge the results of our medical tests from the doctor’s words. But medicine does not stand still, and “it’s better not to know anything!” - becomes an exclamation from a person from the past. Today, “knowing nothing” is still not possible, but you can properly organize your knowledge: find out not much for yourself, but enough to understand the attending physician. This book was written to help you first “decipher” the results of the most common medical tests, make their own assessment and simply be able to talk about themselves with a good, attentive doctor. The book is not a special medical reference book, but it is a convenient and useful tutorial for the average clinic patient.
