IDEXX VetTest® Dry-Slide Technology

Ensuring accuracy by minimising the effects of interfering substances.

As you know, drawing a clean sample from a pet is not an easy task, especially when animals are ill or stressed.

• Samples from patients who have recently eaten may be lipemic (fatty serum).

• Samples from sick patients may be icteric (jaundice).

• Samples from a patient that struggles during the exam may be haemolytic (red-tinged serum).

The following diagram shows how VetTest dry-slide chemistry slides are designed with a unique filtering layer to minimize the effects of these interfering substances.

Patient sample is applied to the top of the spreading layer.

Spreading layer: Sample is distributed evenly

Filtering layer: Filters out substances that interfere with results
Reagent layer: Reagent reacts with sample

Indicator layer: Reacted sample collects for spectral analysis
Support layer: Optical interface

The layered dry-slide design filters out substances that can interfere with results, providing greater accuracy.

Blood samples containing these interfering substances can effect results, and are more common than you may think. In fact, a recent study showed that as many as 75% of blood samples in veterinary medicine can be affected by interfering substances.* That’s why it is essential for your chemistry analyser to provide accurate results—even when samples are compromised.

Over 50 million patients have been tested to date using the IDEXX VetTest, making this technology the most preferred, proven chemistry method when veterinary teams want uncompromising accuracy for the best patient care.
