“…Similar concentrations of these analytes have been previously reported for sea turtles (Innis et al 2009, Kelly et al 2015. The upward trend of the Ca:P ratio at Facility A and downward trend at Facility B in green turtles was likely associated with differences in dietary supplementation.…”

“…For tissue enzyme elevations at admission, considerations included effects from exertion, capture, and/or handling and transport. During rehabilitation, elevations were likely associated with growth of immature turtles and effects of confinement or problems that developed during captivity (Innis et al 2009, Anderson et al 2013, Petrosky et al 2015. Considering these confounding effects, statistically significant differences in these enzyme activities that were inconsistently observed at different time points during rehabilitation among OCs do not allow for relevant clinical conclusions with regard to adverse effects from oiling.…”

“…Increasing total solids, TP, and ALB during rehabilitation may reflect increased feeding after initial anorexia at admission or greater food availability while in captivity, effects of captive diet composition, or recovery of initially impaired liver function presumptively associated with anorexia, as observed by Innis et al (2009) in cold-stunned turtles during rehabilitation. Since acute inflammation may have been present at admission, hypoalbuminemia as part of an acute phase protein response may also have contributed to initially low concentrations.…”

During the BP Deepwater Horizon (DWH) oil spill in 2010, 319 live oiled sea turtles were rescued and admitted to rehabilitation centers for decontamination and veterinary care. Most turtles were small, surface-pelagic juveniles that were collected from oiled habitat distant from shore. Serial hematology, plasma biochemistry, and blood gas analyses were reviewed to characterize abnormalities relative to observed degree of oiling. Clinicopathological abnormalities upon admission indicated acute, nonspecific metabolic and osmoregulatory derangements that were attributable to a combination of events including stress, exertion, physical exhaustion, and dehydration related to oiling, capture, and transport. Specific toxicological effects reported in other taxa were not observed. Initial point-of-care blood data from one rescue center were evaluated using clinical assessment of physiological status for all turtles of all species with available data for pH, pCO 2 , sodium, and potassium. In addition, a prognostic model that was specifically developed for cold-stunned Kemp's ridley sea turtles Lepidochelys kempii was applied to oiled Kemp's ridley turtles from one center. Thirty-six percent of oiled turtles were identified as physiologically de ranged based on a clinical assessment of their physiological status, and 25% of oiled Kemp's ridley sea turtles exceeded the mortality risk threshold of the prognostic model. These results indicate that the physiological derangements in these animals were relatively severe and clinically relevant. Based on observations during the DWH spill, adverse physiological effects in sea turtles may be an important consequence of stress, exertion, physical exhaustion, and dehydration secondary to oiling, capture, and transport.

“…To determine the significance of alterations in biochemical and hematological values, it is essential to establish species-specific (or at least taxon-specific) normal values for parameters of interest. Reference intervals for certain chelonian species, including sea turtles [2], [5], [6], [8]–[10], [12], [15], [18], [19], [24], [33], [34], [39], [46], [60], have been widely investigated. Additionally, wild sea turtle blood gas values have been reported and analyzed [28], [55].…”

The green turtle, Chelonia mydas, is an endangered marine chelonian with a circum-global distribution. Reference blood parameter intervals have been published for some chelonian species, but baseline hematology, biochemical, and blood gas values are lacking from the Galapagos sea turtles. Analyses were done on blood samples drawn from 28 green turtles captured in two foraging locations on San Cristóbal Island (14 from each site). Of these turtles, 20 were immature and of unknown sex; the other eight were males (five mature, three immature). A portable blood analyzer (iSTAT) was used to obtain near immediate field results for pH, lactate, pO2, pCO2, HCO3 −, Hct, Hb, Na, K, iCa, and Glu. Parameter values affected by temperature were corrected in two ways: (1) with standard formulas; and (2) with auto-corrections made by the iSTAT. The two methods yielded clinically equivalent results. Standard laboratory hematology techniques were employed for the red and white blood cell counts and the hematocrit determination, which was also compared to the hematocrit values generated by the iSTAT. Of all blood analytes, only lactate concentrations were positively correlated with body size. All other values showed no significant difference between the two sample locations nor were they correlated with body size or internal temperature. For hematocrit count, the iSTAT blood analyzer yielded results indistinguishable from those obtained with high-speed centrifugation. The values reported in this study provide baseline data that may be useful in comparisons among populations and in detecting changes in health status among Galapagos sea turtles. The findings might also be helpful in future efforts to demonstrate associations between specific biochemical parameters and disease.

Hematologic and plasma biochemical findings in cold-stunned Kemp's ridley turtles: 176 cases (2001–2005)

Abstract: Cold-stunned Kemp's ridley turtles may be affected by electrolyte derangements, dehydration, and decreased renal function. Hematologic and plasma biochemical evaluation of such turtles provided useful clinical and prognostic information during the rehabilitation process.
