The recommendations are based on 14 questions encompassing all steps of the process: indication for the test, blood sampling (timing of blood collection, blood volume, tubes), transport to the laboratory, techniques applied, normal values, dose adjustment, and reporting the results.
Conditions of sampling, timing after graft flushing, and the technique of the graft flushing were well standardized as Fazakas and colleagues [ 8] proposed in order to avoid any bias in intensity of PCT peak after reperfusion.
These conflicting results may be because of the various techniques used, the biological samples analyzed, timing of sampling, and differences in subject selection.
The significance of the difference in sample timing at the two treatment time points should be clarified in the text.
SeHCAT testing, which integrates bile acid loss over a 7-day period, does not have these drawbacks of sample timing and processing, but clearly involves more time commitment from the patient to have two scans.
Karlsson et al. proposed alternative RUV models describing serially correlated errors (e.g., autocorrelation), which can arise from structural model misspecification, and time-dependent errors arising from inaccurate sample timing.
The receiver needs to determine at which time instants the incoming signal has to be sampled (timing synchronization).
where z v) is the time domain samples of the signal under test, t ∼ is the sample timing difference between the FFT processing window in relation to nominal timing of the ideal signal, f ∼ is the RF frequency offset, ϕ ∼ t, f is the phase response of the Tx chain and ã t, f) is the amplitude response of the Tx chain.
Similar patterns of sample timing were described for trauma patients.
Sample timing and key aspects of experimental technique were compared between sepsis and control subjects.
