Abstract There is often a demand for statistics to evaluate and improve different analytical methods. This is especially important in forensic DNA analysis, facing a wide variety of items and substrates, from which samples are collected. For LT DNA analysis it is valuable to have data showing what kind of results that are received, readily divided into different categories of items. We have developed a database showing the success rates for different items. During the years 2008–2010 LT DNA results were collected in 417 cases, with a success rate of 38%. Corresponding success rate per sample in the different categories of items (i.e. knives, electronics and bombs, letters and envelopes) vary between 7% and 19%.
