SD, standard deviation; RBC, red blood cell; HGB, hemoglobin; HCT, hematocrit; MCV, mean corpuscular volume; MCH, mean corpuscular hemoglobin; MCHC, mean corpuscular hemoglobin concentration; WBC, white blood cell; LYM, lymphocytes; MON, monocytes; NEU, neutrophils; EOS, eosinophils; BAS, basophils; PLT, platelets; MPV, mean platelet volume. Mann-Whitney U-test for nonnormally distributed parameters was done between trimesters: All hematological parameters showed significant differences between first, second, and third trimester. P < 0.05 was considered as statistically significant. Comparison between trimesters of pregnancy: Comparing the three groups two by two using a post-hoc test shows that there is a statistically significant difference between the three groups taken two by two |
