Description The determination of hematological values is used to obtain knowledge about the health conditions of animal species. The big-headed Amazon River turtles, (Peltocephalus dumerilianus)are considered one of the least known testudine species concerning their biology and health status. Herein, we determined the hematological and plasma biochemical parameters of 17 (eight males and nine females) adult P. dumerilianusto provide reference interval values for clinically healthy individuals. We collected the blood samples by puncturing the femoral vein using long heparinized hypodermic syringes. Sexual dimorphism for individuals was determined by external observation of the shape of the plastron. The average values obtained for the ten hematological and biochemical parameters analyzed were red blood cell count = 0.32 million µL-1; hematocrit = 20.6 %; hemoglobin = 8.5 g dL-1; mean corpuscular volume = 681.6 fL; mean corpuscular hemoglobin = 267.8 pg; mean corpuscular hemoglobin concentration = 41.9 g dL-1; glucose = 80.6 mg dL-1, total protein = 4.1 g dL-1, triglycerides = 388.9 mg dL-1, and total cholesterol = 79.3 mg dL-1.  Despite the sexual dimorphism evidenced for the species, there was no significant statistical difference between males and females for both hematological and biochemical parameters analyzed herein. Based on these results, the population is considered healthy, with parameter values coinciding with previously reported reference ranges for testudines species in the region. The results obtained in this study can be used for assessing the health status of other Amazonian turtle populations, especially in actions aimed at cultivation strategies, management, and species conservation.
La determinación de valores hematológicos se ha utilizado para conocer las condiciones sanitarias de algunas especies animales. La tortuga cabezona del río Amazonas, Peltocephalus dumerilianus, se considera una de las especies testudines menos conocidas en relación a su biología y estado de salud. Aquí, determinamos los parámetros bioquímicos hematológicos y plasmáticos de 17 adultos (ocho machos y nueve hembras) de P. dumerilianus con el fin de proporcionar valores de intervalo de referencia sobre los individuos clínicamente sanos. Recolectamos las muestras de sangre perforando la vena femoral con jeringas hipodérmicas largas heparinizadas. El dimorfismo sexual de los individuos se determinó mediante la observación externa de la forma del plastrón. Los valores medios obtenidos para los diez parámetros hematológicos y bioquímicos analizados fueron: recuento de glóbulos rojos = 0,32 millones µL-1; hematocrito = 20,6 %; hemoglobina = 8,5 g dL-1; volumen corpuscular medio = 681,6 fL; hemoglobina corpuscular media = 267,8 pg; concentración media de hemoglobina corpuscular = 41,9 g dL-1; glucosa = 80,6 mg dL-1, proteína total = 4,1 g dL-1, triglicéridos = 388,9 mg dL-1y colesterol total = 79,3 mg dL-1. A pesar del dimorfismo sexual evidente para la especie, no hubo diferencia estadística significativa entre machos y hembras para los parámetros hematológicos y bioquímicos analizados aquí. Con base en estos resultados, la población se considera saludable y los valores de los parámetros coinciden con los rangos de referencia reportados previamente de las especies de testudines en la región. Los resultados obtenidos en este estudio pueden utilizarse en la evaluación del estado de salud de otras poblaciones de tortugas amazónicas, considerando especialmente aquellas acciones dirigidas al manejo, conservación y estrategias de cultivo de la especie.
