Ro sings sign is referred rebound…so it is RLQ pain after testing for rebound tenderness in the LLQ…not direct tenderness in the LLQ causing RLQ pain…

When you talk about elevated numbers can you PLEASE always tell us what's normal??? Here's what I found on Google: The normal range of the percentage of neutrophils is between 45% and 70%,  A normal (absolute) neutrophil count is between 2500 and 7500 neutrophils per microliter of blood.
