The relationship between RBC indices and platelet count with thyroid hormones. There were significant correlations between Hb, Hct, MCH, and MCHC with T3 in hypothyroidism. The significant correlations between RBC indices, platelet count, MCV, and RDW with T3 was not observed (A, D, G, J, M, P and S). There were significant correlations between Hb and Hct with T4, and also the significant correlations between the counts of RBCs and platelets, as well as MCH, MCHC, MCV, and RDW with T4 was not observed (B, E, H, K, N, Q, and T). We revealed significant correlations between Hb, Hct, MCH, and TSH. The significant correlations between RBC, MCV, MCHC, RDW, and platelet count with TSH was not observed (C, F, I, L, O, R and U)
