ABSTRACT
Objective: To find the diagnostic accuracy of red cell distribution width in iron deficiency anemia, taking serum ferritin as gold standard among pregnant Pakistani women.
Study Design: A descriptive cross-sectional study
Place and Duration of Study: This study was conducted at the Department of Obstetrics & Gynaecology, Allied Hospital, Faisalabad from April to October 2021.
Methods: A descriptive cross-sectional validation study was carried out at Department of Obstetrics & Gynaecology, Allied Hospital, Faisalabad to determine the diagnostic accuracy of RDW in IDA, taking serum ferritin as gold standard.
Results: In 115 RDW positive patients, 100 (True Positive) had iron deficiency anemia and 12 (False Positive) had no iron deficiency anemia on serum ferritin levels. Among, 88 RDW negative patients, 15 (False Negative) had iron deficiency anemia on serum ferritin levels whereas 73 (True Negative) had no iron deficiency anemia on serum ferritin levels. Overall sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of red cell distribution width in iron deficiency anemia, taking serum ferritin as gold standard was 86.96%, 85.88%, 89.29% 82.95% and 86.50% respectively.
Conclusion: This study concluded that diagnostic accuracy of RDW in diagnosing IDA in pregnant women is very low.
