Hello, Wellcome to HCM
EFW means Estimated metal weight of baby which is nearly 2.6 kg. It is normal for a baby of 36 weeks.
The above mentioned report is a normal report.
There is nothing in the report to worry about.
The report tells that the condition of the baby as well as the external enlivenment for the baby is good.
