The result of the study showed that 3mW laser irradiation of 5 mm spot diameter reduced the viscosity and increased the hydrogen ion concentration (pH) of irradiated blood and ringer solution samples as compared to the un irradiated control value and this change was obvious at 90 minutes of exposure. Thus, the effect of He-Ne laser irradiation depends on irradiation duration. Introduction:
