It can sometimes be useful in diagnosing some diseases, such as multiple myeloma, temporal arteritis, polymyalgia rheumatica, various auto-immune diseases, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease[2] and chronic kidney diseases. In many of these cases, the ESR may exceed 100 mm/hour.

It is commonly used for a differential diagnosis for Kawasaki's disease (from Takayasu's arteritis; which would have a markedly elevated ESR) and it may be increased in some chronic infective conditions like tuberculosis and infectiveendo carditis.
Stages in erythrocyte sedimentation:

There are 3 stages in erythrocyte sedimentation

1) Stage 1 : Rouleaux formation - First 10 minutes

2) Stage 2 : Sedimentation or settling stage - 40 mins

3) Stage 3 : Packing stage - 10 minutes (sedimentation slows and cells start to pack at the bottom of the tube)
Normal values

Note: mm/h. = millimeters per hour.

Westergren's original normal values (men 3 mm and women 7 mm)made no allowance for a person's age and in 1967 it was confirmed that ESR values tend to rise with age and to be generally higher in women. Values are increased in states of anemia, and in black populations.
Adults:-

The widely used rule calculating normal maximum ESR values in adults (98% confidence limit) is given by a formula devised in 1983:
