The resultant dispersal of relevant content makes it difficult for novices and experienced pathologists to faithfully apply the classification in routine diagnostic work and in clinical trials. The results show that all 22 slides (100 %) still have positive result which means the hemoglobin crystal still could be found in the contaminated bloodstain using Teichmann and Takayama test.
