Background: Magnetic field is now recognized by the 21 st 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, rat and little on human showed that magnetic fields induced changes in hematological parameters in these organisms. Purpose: To assess the effect of pulsed magnetic field on platelets count and coagulation process in healthy subjects. Methods: Thirty-one participants divided into two groups, a study group (A) (23 subjects), and a control group (B) (8 subjects). Their ages ranged from 25-40 years. They were selected from the staff members working at the police authority hospital El-Agouza. They were free from any health problems and not previously treated by magnetic field. Group (A) 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) didn'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 INR. Results: showed that group A that received pulsed magnetic field had significant increase of platelets count and significant reduction of INR, while the other group had no significant difference in both oh them. Conclusion: Pulsed magnetic field increases platelets count and decreases coagulation.
