They passed tests for cancer markers to my grandmother, because they had already passed everything else, but they could not understand the causes of anemia, the tests came good, they dismissed cancer as the root cause, the result was 2 months after colonoscopy, cancer was found, 3 stages with metastases. And of course, the tests taken by another laboratory were off the scale. As many as 2 months were lost because of them! I don't recommend it to anyone.
