The coefficient (limit) of repeatability demonstrated that 95% of the differences measured for skin displacement and pressure were less than 6%and94%4% of their respective means.
The set targets for concentrations lower than 100 μg L−1 were standard deviation of repeatability (sr) below 10% and limit of repeatability (r) below 28%, while for concentrations higher than 100 μg L−1, sr below 7% and r below 20%.
The obtained limit of quantification, repeatability, and measurement uncertainty were satisfactory.
Besides the methodological aspects, the obtained analytical results and relevant performance characteristics (e.g. measuring range, limit of detection, repeatability, reproducibility, trueness, and expanded uncertainty of measurement) are determined and discussed.
We used a conservative cut-off of CT<27 to score individuals as 'positive' or 'detected' for the calculation of prevalence; this equates to a CT of 35 36 on the ABI 7900 and is near the upper limit of reliable repeatability on the ABI instrument.
A few performance parameters, including linearity, limits of detection (LODs), repeatability and recovery, were investigated using samples with unknown levels of volatile components.
Confidence in 3D multi-segment foot models has been limited by a lack of repeatability data, particularly in older populations that may display unique functional foot characteristics.
In such cases, method validation could be limited to the determination of repeatability, linearity and specificity.
In addition, helical multi-detector row CT exposes the patient to a substantial radiation dose, which limits the repeatability of the procedure [ 6].
Analytical performances, such as limits of detection and quantification, repeatability of the over-all procedure and accuracy, by analysing GBW-08571, DORM-2, DOLT-3 and TORT-2 certified reference materials, were finally assessed.
