Stall Side Blood Analyzers

In a recently published paper, two blood proteins, fibrinogen and serum amyloid (SAA), that signal inflammatory conditions (illness/injury), were evaluated with respect to their potential to

help veterinarians quickly assess the health status of a horse, especially those horses in training. The study looked at Thoroughbred horses in race training where a balance must exist between training to maximize performance with overtraining that can lead to injury and a compromised immune system. Often times, clinical symptoms of a health issue may only become apparent when the increased stress has occurred, so finding a way to determine these underlying problems before there is a significant health issue has become a priority. Most commonly, changes in the white blood cell count (WBC) in a blood sample, as well as the types of white cells that are there, have been used to monitor a horse’s health. Unfortunately, the WBC count can go up and down when the horse is challenged and can show wide variation in healthy horses, making interpretation sometimes difficult. Fibrinogen and SAA, however, seem to show promise in consistently detecting horses with an underlying inflammatory condition, due to some level of illness or injury, as their values tend to rise and fall together. The positive impact of this – these two proteins can identify those horses that are having an inflammatory response. Negative aspect – a test using these two proteins will not identify horses suffering from medical issues that do not cause an inflammatory response. Conclusion: that fibrinogen and SAA have “excellent potential as biomarkers” and are likely give more information about conditions that are relevant to horses in training than the WBC count.

Currently, there is a stall side blood analyzer (“Stable Lab”) on the market that uses this very technology to allow a veterinarian to identify a horse whose fibrinogen and SAA are elevated and to monitor the horse’s response to treatment. Cost of the hand held analyzer/supplies is around $50-$1000 to get started, so this may not be a piece of equipment that every veterinarian will be able to purchase, BUT THE TECHNOLOGY SURE IS EXCITING!!
