Mean platelet volume values for sepsis and control groups was 10.07/8.731 femtoliter (fL) (p=0.000), and 9.45/8.731 fL (p=0.000) for SIRS and control groups. In the group of sepsis patients, the MPV was found to be at cut-off 8.915, sensitivity 71\%, and specificity 63.9\%. In the group of patients with SIRS, MPV was found to be at cut-off 8.85, sensitivity 69.6\%, and specificity 62.5\%. For the MPV/PLT values, the specificity and sensitivity were found to be insignificant.Conclusion: This study shows that although there was no significant reduction in the PLT values between the sepsis and SIRS patients, the MPV and MPV/PLT ratio values were found to have significant differences. However, the specificity and sensitivity of the values were not reliable standard to be used as a test.}, issn = {0379-5284}, URL = {https://smj.org.sa/content/36/10/1186}, eprint = {https://smj.org.sa/content/36/10/1186.full.pdf}, journal = {Saudi Medical Journal} }
