Following analysis of the tests performed on stains on paper, we found that false negatives were detected using tetramethylbenzidine with low-concentration blood samples (1:400000), whereas o-tolidine and leucomalachite green produced the same with samples that were slightly more concentrated (1:200000) and phenolphthalein gave false negatives in samples concentrated at 1:2000.
