Received: September 9, 2019 Revised: October 7, 2019 Accepted: October 12, 2019 Abstract Occupational exposure to benzene from fuel oil in workshop motorcycle workshop causes several health effects, depending upon the level and duration of exposure.
Analysis of blood is important to access the status of workerAo health.
The study aimed to assess the gather basic information required for protecting workersAo health and improve working conditions in the works sites by investigating the ESR levels.

A comparative cross-sectional study of Erythrocyte Sedimentation Rate (ESR) is workers conducted at a workshop motorcycle a blood test that measures a Aused rateAy.
This The study subject involved 100 rate is depends on various factors, namely hemoglobin concentration, the ratio of workers exposed to fuel oil.
All worker plasma proteins, serum lipid concentration, require hematological parameters evaluation, and plasma pH.
It has been a widely used especially in ESR levels.
All workers were marker for inflammation and indicates asked to give informed consent.
