When patients have hCT levels higher than the gender-specific upper limits, the underlying cause must be thoroughly investigated.
The most common approach of normalizing values by lab-specific upper limits of normal may be supplemented by normalization using the patient's baseline values.
The aims of this study were thus two-fold: first, to determine inter- and intra laboratory variation as expressed by the statistics of the ISO standard, among 10 veterinary laboratories in Northern Europe, and second, to compare the results from an individual laboratory with its own specific upper reference limit.
The Initiating Dialysis Early and Late trial had no specific upper age limit and included patients up to age 74 years (mean: 62 years).
26 However, to date contemporary assays have not had the sensitivity and precision to quantify troponin in more than 90% of healthy people and therefore were unable to determine sex specific upper reference limits.
More specifically, the authors are endorsing the report of the 2015 Dietary Guidelines Advisory Committee, of which I too am a fan, in which there is no specific reference to an upper limit for total dietary fat intake.
24 Where Emax models have been utilized for clinical QTc changes, the maximal activity level appears to be compound-specific rather than reaching a system-specific or physiological upper limit (for example, 20 ms for vernakalant 25 and 170 ms for N-acetylprocainamide 26).
Across-breed prediction is particularly challenging because, in addition to the possible occurrence of inconsistent LD between markers and QTL [ 5, 6], QTL may be breed-specific, which places an upper limit to the accuracy that can be reached in another breed.
To push myself further, I create a create a lower and upper limit (in daily hours).
In stem mass ranging in the order of 10 mg to 1 g (equivalent to 2.3 mm and 23 cm in Weymouth) that are encountered in INT determination experiments, there seems to be a threshold INT (upper limit or saturated value) specific to the stem of each blueberry cultivar.
