SWVs and variability are different depending on the depth and the frequency used. SWVs with a low frequency probe had a tendency to be higher at the same depth. To reduce variability of SWV, a high frequency probe is recommended for a depth of 2-3 cm, and a low frequency probe is recommended for a depth of 4-5 cm.

Sepsis patients demonstrated significant changes in routine and CPD items related to RBC, neutrophils, lymphocytes, and platelets when compared to NCs. Increase in CPD items NE-SFL and NE-WY, which may indicate neutrophil immaturity or activation, could be useful for the detection of sepsis patients, in conjunction with currently used surrogate sepsis biomarkers. However, these items did not efficiently contribute to the discrimination of sepsis severity or predict mortality.
