What does a low result mean?
A slow sedimentation rate is an entirely reassuring finding reflecting normal blood fluidity.
What does a high result mean?
A mildly increased rate is very common with advancing age, menstruation, pregnancy, or recovering from a virus.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Is this sedimentation rate standard for my age and gender?
- Does CRP confirm whether inflammation is currently active?
- Is a routine recheck in a few weeks suggested?
Do you have a full blood test report?
