Question

question 5 (mandatory) (20 points) listen which test is definitive for pernicious anemia? bone marrow biopsy serum ferritin mma schilling test

Explanation:

Pernicious anemia is caused by the body's inability to absorb vitamin B12 due to a lack of intrinsic - factor. The Schilling Test is used to assess vitamin B12 absorption and is definitive for diagnosing pernicious anemia. Bone marrow biopsy is more for overall marrow - related disorders, serum ferritin is for iron - status assessment, and MMA (methylmalonic acid) is a marker but not as definitive as the Schilling Test for pernicious anemia diagnosis.

Answer:

D. Schilling Test
