According to Trehan, a detailed health bulletin would be released in the evening once Hazare's blood report comes in.

"The reports of his blood test will come in the evening but his health is a matter of concern and the effects of fasting on his body will have to be monitored closely," said Trehan.

"He is being examined every two hours," he added.
