To determine whether a smartphone obtained image can be used to extrapolate the packed cell volume of canine blood samples.

Prospective study of surplus blood obtained from clinical cases Setting University teaching hospital Interventions Blood samples were placed on filter paper and images were obtained with a smartphone in different environments. These results were then compared to the packed cell volume measurements on the same samples following the World Health Organisation guidelines.

69 samples were assessed and identified that smartphone images, obtained in a controlled environment, were able to predict the packed cell volume of the samples. This prediction was most accurate when assessing samples of a normal erythroid mass or polycythaemic samples.
The results of this study suggest that smartphone obtained images are indeed of use when correlated with canine packed cell volume. If this can be incorporated into a smartphone application, there would be scope to use this in low resource settings.
