Heska Introduces the HemaTrue(TM) Veterinary Hematology Analyzer

LOVELAND, Colo., July 14 /PRNewswire-FirstCall/ -- Heska Corporation ("Heska"), a leading provider of advanced veterinary diagnostic and specialty veterinary products, announced the official introduction of its new HemaTrue(TM) Veterinary Hematology Analyzer today at the 144th Annual American Veterinary Medical Association (AVMA) Convention in Washington, DC. A significant upgrade to the company's CBC-Diff(TM) analyzer, the HemaTrue(TM) Veterinary Hematology Analyzer is the latest advancement in Heska's line of in-hospital veterinary instruments.

Like a complete blood count (CBC) analyzer in human medicine, the HemaTrue(TM) Veterinary Hematology Analyzer counts blood cells, enabling veterinarians to determine whether abnormalities exist. It also enables them to determine whether more detailed tests are indicated. By providing reference lab-quality hematology results in just 55 seconds, veterinarians and their staff members are able to determine treatment options and discuss them with the pet owner right away.

"Having confidence in test results gives veterinarians confidence in their treatment decisions," says Dr. Julie Gamble of Gamble Pet Clinic. "With the HemaTrue(TM) analyzer, Heska has once again demonstrated its commitment to introducing industry leading advancements that give veterinarians the tools they need to practice better medicine."

In-hospital hematology testing is valuable in emergency situations, routine medical exams, and for use with geriatric patients. It also provides peace of mind and added convenience to pet owners by eliminating the need to wait for hematology results to come back from the lab.

In keeping with its "Smarter, Together" promise, Heska's HemaTrue(TM) analyzer provides veterinarians fast, accurate, repeatable, reference-lab quality results for prompt treatment decisions. The HemaTrue(TM) Veterinary Hematology Analyzer is a state-of-the-art, streamlined design that takes up less space in veterinary hospitals and features multiple enhancements for unprecedented ease of use and uncompromised precision and accuracy.

Heska will provide live demonstrations of the new HemaTrue(TM) analyzer at booth 308/310 at the AVMA Convention which begins July 14, 2007.

The HemaTrue(TM) analyzer comes with a three-year warranty and 24/7 Emergency Technical Support.
