Using NBA, the limit of detection of DNA was estimated to be about 20 ng, which is sensitive enough for most school investigations.
There are many approaches used to calculate the limit of detection; therefore, the laboratory should define its approach for determining a limit of detection.
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.
We established a protocol for the testing of HCV-infected individuals; this protocol's initial analysis was a quantitative reverse transcriptase polymerase chain reaction (RT-PCR) HCV determination, and only when this test's result was below the limit of detection was the qualitative RT-PCR assay performed.
Confidence intervals for the precision profile, limits of quantification, and limit of detection are based on the 95% confidence interval limits for pooled standard deviation.
