Green turtle, Chelonia mydas, Hematology, Reference values, Blood


The hematological reference ranges of sixty wild, apparently health, juvenile green sea turtles (Chelonia mydas) from the Fernando de Noronha Archipelago, Pernambuco State, Brazil, were determined between the months of July and September of 2003. The obtained results were: Packed cell volume 21,4-36,6 %; erythrocytes count 0,244-0,554 x10(6)/µl; Hemoglobin 5,9-14,0 g/dl; Mean Corpuscular Volume 500,4-986,1 fl; Mean Corpuscular Hemoglobin 144,0-367,1 pg; Mean Corpuscular Hemoglobin Concentration 23,7-45,1 g/dl; Total leucocytes count 1178,8-8259,6 /µl; Monocytes 15,4-1494,3 /µl; Lymphocytes 221,1-1924,8 /µl; Heterophils 621,5-4317,8 /µl; Eosinophils 96,1-1831,0 /µl; Basophils 0,0-45,3 /µl; Trombocytes 9513,2-36316,5 /µl. The comparison between the obtained results and literature data reinforce the need to establish hematological counts for specific agglomerations on different geographic and climate conditions, size classes, age, and methodologies. Because of these influences, the values should not be extrapolated to other C. mydas agglomerations and should be used carefully for the clinical evaluation of individuals under other conditions.
