Background: The present study aims to compare hemophilic patients’ fingerprint types with the normal people to help diagnose the disease, particularly new occurrences of the disease. Method: This case control study was conducted in 2012. Sixty two patients with hemophilia type A and 62 normal healthy people were selected. The type of fingerprint was determined by a forensic specialist who was kept unaware of the participants’ group. Using advanced Henry method, the main types of fingerprints were classified as arch, loop, whorl, as well as other types. Results: In the control group, loop type (65%) and in the case group the whorl type (34%) were the most frequent fingerprint type (p<0.001) and there was a significant difference of fingerprint in each finger between two groups. In addition, the average number of whorl type in the patients with mild disease was significantly higher and the average
number of arch and other types of fingerprints was significantly lower than patients with moderate or severe disease.
