CBC options at IDEXX Reference Laboratories provide diagnostic flexibility

By M. Alexis Seguin, DVM, MS, DACVIM

Accurate and comprehensive

All complete blood counts (CBCs) performed at IDEXX Reference Laboratories use the most advanced hematology technology available. Fluorescent laser flow cytometry methods and veterinaryspecific algorithms make it possible to provide automated CBC results with an extremely high level of accuracy.

IDEXX CBCs are also the most comprehensive. They are the only CBC to include both:

  • 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 or underlying hemolytic disease.
  • 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 blood loss or inflammation in anemic and nonanemic patients.

Flexible, easy-to-understand options

IDEXX Reference Laboratories offers the following CBC ordering options to give you the diagnostic flexibility you need to meet the individual needs of your patients.

IDEXX CBC typically used for preventive care screening

The IDEXX CBC is the appropriate and most cost-effective option for routine preanesthetic or preventive care screenings on clinically healthy animals. Available for canine, feline, and equine patients, this option provides an automated CBC, including hemogram, five-part differential, platelets, platelet indices, as well as (for canine and feline patients) reticulocyte count and reticulocyte hemoglobin.

IDEXX CBC-Select recommended for sick patient diagnostics

The IDEXX CBC-Select is the option recommended for sick patients. It includes the same components as the IDEXX CBC, as well as a blood film evaluation by a technician to evaluate for abnormal red and white blood cell morphology, blood parasites, unclassified cells, and immature cell lines. A clinical pathologist review is automatically included when results are markedly abnormal or when unclassified cells are seen based on specific established criteria.

CBC options from IDEXX Reference Laboratories

When viewing IDEXX test results in VetConnect PLUS, access differential diagnoses (including those for reticulocyte and reticulocyte hemoglobin) instantly, helping you interpret and act on any results that are abnormal for your patient.

Options for abnormal CBC results

The IDEXX CBC 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 CBC or chemistry results. A positive heartworm antigen or tick/vector screen may also be an indication to evaluate a blood film review in a clinically healthy animal.

IDEXX Reference Laboratories offers the CBC Blood Film Evaluation. This add-on (test code 3900) allows you to request an evaluation of the blood film by a technician on your previously submitted IDEXX CBC. See order options for more information.
