ESR stands for erythrocyte sedimentation rate, which is a blood test that measures how quickly red blood cells settle at the bottom of a test tube. A high ESR value usually indicates the presence of inflammation in the body.
An ESR value of 90 is considered extremely high and may indicate a serious underlying medical condition. However, it is important to note that an elevated ESR value alone does not provide a definitive diagnosis and additional testing and evaluation by a healthcare professional is necessary.
Possible causes of a high ESR value include infections, autoimmune diseases, cancers, and chronic inflammatory conditions. Your healthcare provider will need to evaluate your medical history, perform a physical examination, and order additional tests to determine the underlying cause of your elevated ESR.
It is important to follow up with your healthcare provider and undergo any recommended tests or treatments to address any underlying medical conditions.
