Table 2. Hematology and plasma biochemical parameters that exhibited significant variation between the fall (October and November) and summer (May through September) sampling periods in juvenile loggerhead sea turtles (Caretta caretta) sampled in Core Sound, North Carolina, USA.
| Parameter | Fall Median | Summer Median | P-value |
|---|---|---|---|
| Estimated white blood cell count (X 109/L) | 10 | 9 | < 0.0001 |
| Heterophils (X 109/L) | 6.4 | 4.1 | < 0.0001 |
| Monocytes (X 109/L) | 2.8 | 1.0 | 0.0001 |
| Total protein (g/L) | 37 | 33 | 0.0020 |
| Globulin (g/L) | 26 | 22 | 0.0040 |
| Blood urea nitrogen (mmol/L) | 34 | 24 | 0.0001 |
| Packed cell volume (%) | 29 | 31 | 0.0003 |
| Chloride (mmol/L) | 114 | 116 | 0.0300 |
Only blood urea nitrogen differences met criteria for partitioning by season for reference intervals.
