Conclusionsīased upon this comparative prospective survey, all in-clinic and laboratory DAT techniques produced similar results when performed by trained personnel and can therefore be recommended for detection of antibody-coated erythrocytes and immunohematological diagnosis. Of the sample from 12 DAT+ dogs collected during treatment, 10 remained DAT+ when tested 1–24 weeks after initial assessment. Clinical follow-up was available for 42 dogs. There was good correlation between spherocytosis and DAT results from the six DAT techniques, but the correlation with autoagglutination was only fair.
Among the DAT+ samples, 57% had agglutination, 87% had spherocytosis, and 45% had both. Macroscopic agglutination in tubes or on slides was observed in 48 samples after 1:1 and 1:4 blood to saline dilution, but only persisted in four samples after washing. DAT+ dogs were more severely anemic and more likely to have erythroid regeneration compared to DAT- dogs. Notably, DAT results were comparable and consistent across all evaluated methods regardless of antiglobulin and temperature used. Among the 126 samples submitted for DAT 67 were positive by a DAT utilizing microtiter plates with goat anti-dog antiglobulin DAT at 22☌. Samples from healthy dogs yielded negative results with all immunodiagnostic tests. Samples were also subjected to different DATs: a gel minitube and an immunochromatographic strip kit used in clinics neutral gel column cards, microtiter plates (at 4°, 22°, and 37☌), capillary tubes, and flow cytometry used in laboratories. Material and methodsĪnticoagulated blood samples from 126 dogs suspected of having IMHA submitted to a diagnostic veterinary laboratory for a routine direct antiglobulin test (DAT) and from 28 healthy control dogs were evaluated for spherocytosis and autoagglutination before and after three saline washes. As data on the performance of immunohematological tests was lacking, we undertook a comparative analysis. Discard the other two parts of the ejaculate if not required for any diagnostic tests.A 2019 ACVIM consensus statement on diagnostics for immune-mediated hemolytic anemia (IMHA) in dogs made testing recommendations. After collection, remove tube containing the second “Sperm Rich” fraction of the ejaculate from the blue funnel.Take sample to the laboratory for sperm evaluation and semen processing. At the end of spermatic ejaculation, when active contraction of the prostate is observed (contraction of the perineal region), use the third white funnel to collect the final fraction of the ejaculate (transparent prostatic fluid) which is usually high in volume. At the end of passive production of the first fraction, often when thrusting stops and the dog begins rotating, the “Sperm Rich” fraction is actively produced, quickly change to the blue funnel to collect the desired sample (normally cloudy). Avoid touching the penis with the funnel. When the stud dog begins his penile erection, position red funnel close to the tip of the penis to collect the first fraction of the ejaculate (normally transparent).

It also helps to identify penis problems like vesicles, lesions, bleeding and inflammation during full erection. Mixing fractions will adversely affect the quality of collection semen.The funnels allow better visualisation of the different fractions of the ejaculate, making separation easy.
