False Positives / Negatives

Samples with strongly degraded bacterial DNA will give the result “no species identification possible”. To avoid false-positive results, a negative control (water) is always co-analysed with the samples.

With NGS all bacterial DNA amplicons that were successfully amplified from the sample DNA will be detected. Due to the high sensitivity of the method, sequences with low presence in the sequence pool or sequences with unexpected sequence lengths have to be removed from the data analysis during the bioinformatical workflow in order to exclude false-positives due to PCR and/or sequencing errors. Species with a fraction below 0.5 % of all assigned reads are not reported.
