Data
A cross-sectional study was performed including 604 BAL samples, from
clinical cases, submitted by referring veterinarians all over Denmark
during the period between 2016-2019, to the diagnostic service at the
University of Copenhagen. A questionnaire and further information were
provided from both the horse owner and referring veterinarian about the
horse, clinical symptoms and BAL procedure. Duplicate samples were
excluded from the analysis. Furthermore, data were excluded if another
BAL volume than 200-250 ml was used, if shipping had been delayed or if
the sample was of a non-diagnostic quality.
