Evaluation of three methods for measurement of hemoglobin and calculated hemoglobin variables with the ADVIA 120 and ADVIA 2120 systems in goats.
The present study investigated 3 methods of hemoglobin (Hb) determination in goats using the ADVIA 120 and ADVIA 2120 systems. Ethylenediaminetetraacetic acid anticoagulated caprine blood samples (n = 40 goats) were subjected to Hb determination via the cyanmethemoglobin methods in both instruments and a novel, cyanide-free, colorimetric method with the ADVIA 2120. Statistical analysis of the data included a linear regression, Passing-Bablok regression, and Bland-Altman diagram. ⋯ However, imprecision was higher compared to colorimetric methods. Excellent to fair agreement was evident for all calculated erythrocyte and Hb variables. Because of the excellent correlation between the ADVIA 120 and ADVIA 2120, the cyanide-free method of Hb determination could be used with caprine blood specimens; however, the proportional bias must be considered.

An 11-year-old, neutered, male Golden Retriever cross dog was euthanized following a history of recurrent pericardial effusions. At necropsy, blood-tinged pericardial and intrathoracic effusions were seen along with numerous firm to hard plaque-like masses that studded the epicardial, pericardial, mediastinal, and costal pleural surfaces. Within the right thorax, the lesions coalesced into a large mass that occupied most of the cavity. ⋯ Transmission electron microscopy corroborated the presence of intracytoplasmic vacuoles and demonstrated prominent intercellular junctional complexes and apically located microvilli. These findings are consistent with a lipid-rich variant of mesothelioma. To the authors' knowledge, this is the first report of a lipid-rich mesothelioma in a dog.
