Background: Magnetic field is now recognized by the 21st century medicine as real physical entities that promise the healing of various health problems. In the last few decades, various studies refer to biological effect of magnetic field exposure have been in progress. Most of studies carried out on mice, rabbits and little on human showed that magnetic fields induced changes in hematological parameters in these organisms. Purpose: To investigate the effect of pulsed magnetic field on platelets count and coagulation process in healthy subjects. Methods: Forty- three healthy subjects divided into two groups, a study group (A) consists of (23 subjects) 11 females and 12 males, and a control group (B) consists of (20 subjects) 10 females and 10 males. Their ages ranged from 25-40 years. They were selected randomly from the staff members working at department of physical therapy of police authority hospital El-Agouza. They were free from any health problems and not previously treated by magnetic field. Group (A) (Study group) received magnetic field for 12 sessions successively over one month by the rate of 3 sessions per week, with low frequency (10 HZ), low intensity (10 G) and for 20 minutes, While Group (B) (control group) didn{u2019}t be exposed to magnetic field just placement in the device as a placebo. The subjects were evaluated pre and post exposure for both platelet count and international normalized ratio (INR). Results: Time-by-group statistically significant effects (mixed design MANOVS) of platelet count and INR were found for the 2 groups. The effect of the tested group on platelets count revealed that there was a significant differences of the mean values of the "post" treatment between both groups and this significant increase in favor to study group. Considering the effect of the tested group on INR revealed that there were a significant differences of the mean values of the "post" treatment between both groups and this significant reduction in favor to the study group. Conclusion: The findings of the study revealed that there was a significant effect of pulsed magnetic field on platelets count and coagulation process in healthy subjects
