Evaluation and establishment of reference intervals using the i-STAT1 blood chemistry analyzer in turkeys.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In veterinary medicine, point-of-care testing techniques have become popular, since they provide immediate results and only small amounts of blood are needed. The handheld i-STAT1 blood analyzer is used by poultry researchers and veterinarians; however, no studies have evaluated the accuracy of this analyzer determined reference intervals in turkey blood. The objectives of this study were to 1) investigate the effect of storage time on turkey blood analytes, 2) compare the results obtained by the i-STAT1 analyzer to those obtained by the GEM Premier 3000, a conventional laboratory analyzer, and 3) establish reference intervals for blood gases and chemistry analytes in growing turkeys using the i-Stat. For the first and second objectives, we used the CG8+ i-STAT1 cartridges to test blood from 30 healthy turkeys in triplicate and once with the conventional analyzer. To establish the reference intervals, we tested a total 330 blood samples from healthy turkeys from 6 independent flocks during a 3-yr period. Blood samples were then divided into brooder (<1 wk) and growing (1-12 wk of age). Friedman's test demonstrated significant time-dependent changes in blood gas analytes, but not for electrolytes. Bland-Altman analysis revealed that there was agreement between the i-STAT1 and the GEM Premier 300 for most of the analytes. However, Passing-Bablok regression analysis identified constant and proportional biases in the measurement of multiple analytes. Tukey's test revealed significant differences in the whole blood analytes between the means of brooding and growing birds. The data presented in the present study provide a basis for measuring and interpreting blood analytes in the brooding and growing stages of the turkey lifecycle, offering a new approach to health monitoring in growing turkeys.
