“…One hundred and twenty-three clinically healthy Holstein cows were randomly enrolled from different dairy farms in the Aegean region of Turkey. The distribution of the study cows within one month postpartum days (PPD) was n = 29 (calving day), n = 29 (PPD 1), n = 12 (PPD 2), n = 15 (PPD 3), n = 7 (PPD 4-5), n = 10 (PPD 6-7), n = 7 (PPD 8-10), n = 5 (PPD 11-16), n = 4 (PPD [17][18][19] and n = 5 (PPD [22][23][24][25][26][27]. Thirty-five of the 123 cows were primiparous (PRP), and the rest (n = 88) were multiparous (MUL).…”

“…Inappropriate nutrition is one of the main causes of metabolic disorders in ruminants (such as acidosis), leading to performance losses in dairy herds (11,12,23). Blood gas analysers need to be validated and compared with pioneer blood gas analysers that have been validated for precision and accuracy, as has been done for the GEM Premier 3000 (4,10,22,24,26). On the other hand, even a small deviation between the measured values can lead to significant differences despite a high correlation, which can be important for the emergency treatment of patients (29).…”

A point-of-care blood gas analyser, Edan i15 Vet (EDAN), was compared with a benchtop blood gas analyser, GEM Premier 3000 (GEM). GEM and EDAN were used to analyse whole blood from 123 lactating Holsteins within one month of calving for blood gases, electrolytes, hematocrit and hemoglobin. EDAN and GEM showed significant linear correlations for blood gases, electrolytes, Hct and Hb. The 95% confidence intervals (CI) of intercept in Passing-Bablok regressions included zero in pCO2, bicarbonate, TCO2, BE ecf, BE B, hematocrit, and pH, but not for Na+, K+, pO2 and sO2. The CI of the slope included 1.0 for Na+, K+, pCO2, bicarbonate, TCO2, BE ecf, BE B, hematocrit, and pH, but not for pO2, sO2, and hemoglobin. The Bland-Altman plots between EDAN and GEM showed a bias of 1.4% for Na+, 2.4% for K+, –1.6% for pCO2, 3.0% for pO2, –5.3% for bicarbonate, 2.8% for SO2, –7.3% for TCO2, 10.4% for Hct, 21.2% for Hb, –25.1% for BE B and –38.5% for BE ecf. The biases in the analysis of certain estimated parameters were much higher (> 5%) than for measured parameters except for Hct. Parity did not correlate with blood gas parameters but blood pH correlated negatively with K+, pCO2 and positively with pO2, TCO2, sO2, bicarbonate, BE ecf and BE B. The postpartum time correlated positively with pCO2, TCO2, BE and bicarbonate and negatively with Hct and Hb values. Reference values (2.5-97.5% quartiles) were determined for each parameter. Conclusively, EDAN can be used interchangeably with GEM for the analysis of blood pH, K+, pCO2 and HCO3 – as they show acceptable moderate agreement. However, they did not agree for other parameters such as TCO2, BE ecf, BE B, Hb, Hct, sO2, Na+, and pO2, therefore, reference values for each parameter were set for GEM and EDAN.

“…We thank Dr. Cembrowski for his useful comments 1 on the accuracy of the GEMÒ Premier TM 4000 blood glucose analyzer (Instrumentation Laboratory Company, Bedford, MA, USA), which appears to depend on the hour of the day. 2 We admit that we were unaware of such intra-day changes in accuracy. Assuming that the older GEMÒ Premier TM 3000 used in our study also shows imprecision in the early morning as suggested by Dr. Cembrowski, this may indeed be another potential limitation of our study.…”
