Blood Count options at IDEXX Reference Laboratories provide diagnostic flexibility
By M. Alexis Seguin, DVM, MS, DACVIM
All blood counts performed at IDEXX Reference Laboratories utilize the most advanced hematology technology available. Fluorescent laser flow cytometry methods and veterinaryspecific algorithms make it possible to provide automated blood count results with an extremely high level of accuracy in our patients.
Our IDEXX blood counts are also the most comprehensive and include the following:
- Reticulocyte count, regardless of the presence of anemia. A reticulocyte count on anemic patients helps to classify the anemia as regenerative or nonregenerative. In nonanemic animals, a persistent reticulocytosis may indicate compensated occult blood loss, underlying hemolytic disease or other chronic diseases. Early identification and management of the underlying disease process is important for a good clinical outcome in these patients.
- Reticulocyte hemoglobin, a measure of the quality of the developing red blood cells in canines and felines. The reticulocyte hemoglobin measures iron availability in developing red blood cells. A decrease in reticulocyte hemoglobin can be seen with chronic blood loss, inflammation and liver disease mostly in anemic patients. We will inform you once available!
Flexible, easy-to-understand options
IDEXX Reference Laboratories offers next to the well-known canine and feline routine profiles with a Large Blood Count, new profile combinations with a Premium Blood Count. All routine hematology/chemistry profiles are also available in both standard and premium versions, allowing you to select the best option depending on your patient’s needs.
Large Blood Count typically used for preventive care screening
The large blood count option is available for canine, feline, and equine patients. This option provides an automated blood count, including hemogram with reticulocytes (for canine and feline), five-part differential, and platelets. Our large blood count option is recommended when performing routine preanesthetic or preventive care screening on clinically healthy animals. For these patients, the large blood count is an appropriate and cost-effective option.
Premium Blood Count recommended for sick-patient diagnostics
The premium blood count is the option recommended for sick canine and feline patients. It includes the same components as a large blood count. Additionally, a microscopic assessment of the blood smear is always conducted and is more thorough than a standard evaluation (e.g. examination for microorganisms). A clinical pathologist is consulted should results be significantly abnormal.
When viewing IDEXX test results in VetConnect PLUS, access differential diagnoses instantly (including those for reticulocyte and reticulocyte hemoglobin1), helping you interpret and act on any results that are abnormal for your patient.
Options for abnormal Large Blood Count results
The Large Blood Count is generally an excellent and economical choice when performing preventive care screening on a clinically normal animal. Sometimes, however, a patient who appears outwardly healthy may in fact have abnormal blood count or chemistry results. A positive tick/vector screen may also be an indication to evaluate a blood smear in an outwardly healthy animal.
IDEXX Reference Laboratories also offers a microscopic differentiation, test code DIFFPR. This additional request allows you an evaluation of the blood smear by a technician on your previously submitted standard Large Blood Count.
