No. it is not necessary to fast before an ESR (erythrocyte Sedimentation Rate) test
No it is not necesary to fast for an ESR blood test.
No From personal experience, I would say no. I have RA and I had to have a ton of blood work and none of the times did I have to fast first. That being said, I would check with your doctor who ordered the labs to be sure, because new tests develop and the requirements for different tests may vary. I am in the same boat and have never been requested to fast before having tests.
For the blood sample, the patient should be fasting (nothing to eat or drink) for at least eight hours before the test

If you must test for cholesterol or glucose, you will. Otherwise, no.
You should fast before a blood drawing because the test being conducted is to measure your natural bodies elements. Foods might alter the composition of your blood.
You should check with your Doctors office to see if you should fast before this test. Each test is different and it is better to be safe than sorry.
