A 30-minute smartphone call exposure significantly prolonged collagen-epinephrine aggregation and increased mean platelet volume in citrated blood.

Plain English Summary

Summary written for general audiences

Researchers collected two sequential citrated blood samples from 16 healthy volunteers and exposed one sample to a smartphone call for 30 minutes at 900 MHz. Exposure significantly prolonged collagen-epinephrine aggregation by a median of 10% and increased mean platelet volume by a median of 5%. Collagen-adenosine diphosphate aggregation and platelet count did not change.

Why This Matters

The study aimed to assess the acute effects of radiofrequency waves emitted by a commercial smartphone on platelet function. The second sample was placed in another plastic rack isolated from radiofrequency wave sources for the same period. Platelet function was evaluated using the platelet function analyser-100 (PFA-100). The authors concluded that smartphone radiofrequency waves induce significant perturbation of platelet structure and function. They cautioned that blood products containing platelets should be kept far away from mobile phones and smartphones throughout the production pipeline and storage period.

This study demonstrates that smartphone radiofrequency waves induce significant perturbation of platelet structure and function, thus providing further support to concerns regarding excessive use of mobile phones. Caution should also be taken with regards to blood products containing platelets, which should be kept far away from mobile phones and smartphones throughout the production pipeline and storage period.
