What could a high sed rate indicate? i am 16 years old and have a sed rate of 89. hemoglobin are also very small and are not the correct shape.

High ESR: May indicate unspecific inflammation.In connection with low hemoglobin, you should have further investigation to make right diagnosis.

Non specific test: Decades ago Dr Mason Guest realized that red cells in a tube would fall at an accelerated rate when they were coated with proteins created by inflammation. That evolved into the sed rate, erythrocyte sedimentation rate. It is often high during chronic infections, or inflammation from any cause. By itself it is a simple indicator like fever.
