This is a clinical video with an excellent explanation of exactly what ESR is and why it’s important to pay attention to an elevated ESR reading. The ESR rate is a general measurement of the blood that can be used to gauge the overall blood health. Elevated ESR readings can indicate a systemic type of infection or disorder, and is used as a first level indicator that there is something wrong. It is non-specific, so there isn’t any indication of the part of the body that may be affected, and there are standards of average set for men, women, children and infants. Anyone that has concerns about an ESR level will find this video a great help in understanding why your medical provider would use an ESR reading.
