CBP, ESR, Serum Iron, TIBC and identified RBC Morphology : Microcytic- Hypochromic smear seen, Anisocytosis-Poikilocytosis. What test covers etiology?

See your doctor. Hypochromic microcitic anemia is most likely due to iron deficiency, but if there is significant poikilocytosis other causes are possible. Your doc may want to send you to a hematologist if the etiology is unclear. Good luck. .
