ESR Value: What Does the Sedimentation Rate Say About Your Health?
The ESR value (erythrocyte sedimentation rate) measures how quickly your red blood cells settle to the bottom of a tube. A higher sedimentation rate may indicate inflammation or infection somewhere in your body. The ESR value typically increases slightly with age. Your doctor can distinguish between a normal age-related change and a value that needs attention. The information on this page is intended as general information and is not a substitute for professional medical advice. Always discuss your results with a doctor.
What It Measures
This test measures the concentration of phylloquinone (vitamin K1) in your blood. It helps assess your vitamin K status and coagulation capacity.
Why It Matters
Vitamin K1 is critical for proper blood clotting and may play a role in bone health. Low levels can be associated with excessive bleeding and may affect bone mineral density. Consult your healthcare provider for personalised interpretation.
When to Test
Testing may be recommended if you bruise easily, experience unexplained bleeding, take blood-thinning medication, or have conditions affecting fat absorption.

Lifestyle Tips
