In the study of Völkel et al. (2008), using the identical analytical procedure and equipment as for biomonitoring samples, no deuterated BPA was detected in the urine of a male human subject who ingested deuterated BPA (dose, 60ng/kg bw), whereas trace amounts of non-deuterated BPA were found in these urine samples.
The histomorphometric reproducibility was estimated from double measurements done by the same person (HD) using identical equipment and set-up (intra-observer variation).
The latter data were available electronically for all workers at all plants, and the evaluation was performed using identical equipment at each location with routine and standardized training of technicians [ 27].
All study and control samples were then prepared in parallel using identical equipment and reagents.
Automated respiratory maneuvers were applied using identical equipment (Evita4Lab-system, Dräger Medical, Lübeck, Germany).
Experiments were performed in microgravity during parabolic flights, and compared to 1g on ground results using identical equipment and procedures in all cases.
In brief, a standardized protocol was implemented, using identical equipment [Basel-Sampler (BGI Inc., Waltham, MA, USA); Teflon filters] and a single weighing laboratory.
Cryoablation was performed under using the Cryo 6 equipment (Erbokryo-CS6 equipment, ERBE, Tübingen, Germany).
"The closeness of agreement of independent test results obtained using the same method on identical test items in the same laboratory by the same operator using the same equipment within short intervals of time".
This means results obtained with the same method on identical test items in the same laboratory by the same operator using the same equipment within a short interval of time [ 8].
