This paper aims to research about the effects of radiating a sample containing the platelet population of the human blood system (ages ranging 18 to 35 years) with low power lasers (wavelengths 632 nm and 532 nm) for a given time. The proposed methodology consists on exposing samples to both radiations. Two more samples, a male and a female, are not exposed, thus working as control groups and allowing quantitative comparisons with the exposed samples. The results showed that after radiating for 30 minutes with the green laser (532 nm), the platelet population from the male sample increased 0.5% while the one from the female sample increased 4.5%; after radiating for 60 minutes, the male sample showed an increase of 3.5% and the female 1.4%. After radiating with the red laser (632 nm) for 30 minutes, the male sample revealed an increase of 7.9%; after radiating for 60 minutes, the male sample presented an increase of 0.7 and the female 5.5%. In conclusion, the experiments demonstrated that 532 nm and 632 nm laser radiation increase platelet numbers in human blood cells.
