An ESR (erythrocyte sedimentation rate) level of 21 mm/h can be indicative of inflammation or infection in the body. Common causes include autoimmune diseases like rheumatoid Arthritis or lupus, chronic infections, or even certain cancers. Other factors such as anemia or pregnancy can also elevate ESR levels. However, it’s important to interpret ESR results in conjunction with other clinical findings and tests for an accurate diagnosis.
