The median CRP levels in the carcinoma, sarcoma and haematopoietic/lymphoreticular disease subgroups were 11.57 (range: 0.52‐313.3) mg/L, 27.56 (range: 1‐348) mg/L, and 11.9 (range: 0.5‐243) mg/L, respectively; the CRP level in the dog with the neuroendocrine tumour was 0.9 mg/L. This evidence concerns the gene CRP and neuroendocrine neoplasm.
