Hemoglobin (Hb) is an oxygen binding protein found in red blood cells and is vital for gas (oxygen and cardon dioxide) transport in the circulatory system. The typical value of hemoglobin varies from species to species and even between breeds (Brenten et al 2016).
Regardless of the actual physiological hemoglobin concentration, red cell mass, and thus oxygen-carrying capacity must remain constant over time in healthy animals. Mature red cells have a finite life span (again, this varies species to species) and their production and destruction must be carefully balanced, or disease ensues.
Hemo Vet allows a veterinarian to quickly assess the hemoglobin concentration of any subject in the clinic or in the field and enable rapid diagnosis of a particular disease state along with other clinical symptoms and initiate treatment.
The following list provides a brief overview of a number of such studies.
