WebRNA contamination can sometimes be detected by agarose gel analysis with routine ethidium bromide staining, although not quantified effectively. RNA bands appear faint and smeary and are only detected in amounts ≥25–30 ng (0.5:1 RNA:DNA ratio). ... such that dsDNA can be accurately quantified in the presence of equimolar concentrations of ... WebMar 12, 2012 · The LOD may be equivalent to the lower LOQ or it may be lower than the lower LOQ. In the latter situation, the test may detect CMV DNA, but the value cannot be accurately quantified. In these cases, the laboratory could report the result as “detected but below the LOQ”; some laboratories report this as “low positive.”
