This finding is important, because patient management that uses cutoffs at either the reported 99th percentile or higher concentrations may have been minimally affected; however, clinicians who use other algorithms for rapid rule-out of myocardial infarction, such as using the limit of detection for rule-out, could have missed individuals with these subsequent lots of hs-cTnT reagents (3).
5(a) (the peak counting rate was taken at a deadtime of 20 %), and estimating a = 1, the values in Table 3 are predicted for concentration limit of detection, [C.
In order to save both physician and patient time as well as to accomplish the joint tasks of quantifying HCV (when possible) and using the lowest limit of detection, simultaneous requests for both quantitative and qualitative HCV tests were common.
5 log10 reduction in HCV RNA was observed in patients receiving VX-950 and peg-IFN; 6 of 8 patients had viral levels below the limit of quantitation (30 IU/mL) at 14 days, and 4 of 8 also achieved viral levels below the limit of detection (10 IU/mL).
The lower limit of detection for the instrument is 10 picograms at a signal to noise ratio of 3 to [1.
The data show rapid reduction of circulating free IgE levels to below the limit of detection in 90% of XmAb7195 treated subjects that had detectable free IgE pre-dose, including those at the lowest dose evaluated of 0.
Turnkey intensified VGA-to-UHD camera engine with video recording and still image capture with limit of detection to single photon counting levels
Alternatively, a false positive may be defined as a result indicating that a drug is present even when a confirmatory method with a lower limit of detection for all compounds present indicates the compounds in question are undetectable.
