The Erythrocyte Sedimentation Rate (ESR or Sed Rate) measures how quickly red blood cells settle at the bottom of a test tube. Faster-than-normal settling often indicates inflammation in the body. While it doesn't pinpoint the cause, it's a useful general marker for infections, autoimmune diseases, and inflammatory conditions.
Blood health testing evaluates your blood cells, clotting factors, and oxygen-carrying capacity to detect anemia, infection, bleeding disorders, and other hematologic conditions.
Anyone investigating unexplained fatigue, frequent infections, bruising, or as part of a routine health check.
