What does ESR stand for?

Estimated Serum Rate
Excessive Serum Recovery
Emergency Support Role
Erythrocyte Sedimentation Rate

The correct answer is: Erythrocyte Sedimentation Rate

The correct answer is Erythrocyte Sedimentation Rate, which is a common laboratory test used to assess inflammation in the body. It measures how quickly red blood cells settle at the bottom of a test tube in a specified period. A higher rate can indicate the presence of inflammatory diseases, infections, or conditions that might require further investigation. This term is well-recognized in the medical field, particularly in relation to diagnosing and monitoring autoimmune disorders, infections, and some types of cancer. The other choices do not match the established medical terminology relevant to laboratory testing and have no recognized meaning in the context of phlebotomy or clinical laboratory practices.
