Details pertinent to reference interval determination can be provided by the AHL Clinical Pathology Technical Supervisor.

*Note:  Horses in training may have significantly higher hemoglobin, hematocrit, and RBC parameters.  A study of 419 clinically well Standardbreds, Thoroughbreds and Quarter Horses in training resulted in the following reference intervals:  hemoglobin 127-188 g/L, hematocrit 0.38-0.55 L/L, and RBC 8.0-11.8 X10 12/L (central 95% intervals).
