Monitoring presence and level of background DNA in forensic DNA laboratory environments can be used to control work routines and cleaning procedures and to follow changes in these, as well as being an indicator for increased/decreased contamination risk. Previous monitoring routines as sampling and interpretation have not been standardised, making it difficult to compare between different sampling events and observe potential trends. Factor analysis was used to generate a simple graphical classification model for unbiased ranking of electropherograms, which can be modified according to user's need, taking into account number of detected alleles, markers and peak height. |
