Аннотация
OBJECTIVE: The Choosing Wisely initiative recommended cessation of folate measurement, suggesting folate supplementation in macrocytic anemia. This study reviewed the need for continued blood folate testing at a large SafetyNet county teaching hospital.
METHODS: Red blood cell (RBC) folate, vitamin B12, iron, ferritin, and hemoglobin results were obtained for utilization review.
RESULTS: Of the 593 RBC folate results, 69 (11.7%) were deficient and 30 (5%) had high values. Collectively, 369 (73.9%) had normal vitamin B12 levels, 342 (70%) had low hemoglobin, 184 (62.5) had normal and 57 (19.4%) had low ferritin, 122 (38.2%) had normal and 188 (59%) had low iron levels. A total of 41 (12%) had normal folate, low ferritin, low hemoglobin, and low iron, suggestive of iron deficiency anemia. There were 11 patients who exhibited low folate, low or normal ferritin, low hemoglobin, and low iron levels, suggesting combined folate and iron deficiency anemias.
CONCLUSION: This study highlights the need for institutions to assess the applicability of national recommendations to their local population.
