My wife had thyroid test. She booked an appointment and ask for thyroid profile test which cost 400rs. However on invoice they charged for thyroid panel test which is 550rs.. Both test give same result and have same components. Also they are charging 100rs as collection charges.. Which ideally should be null as they have policy to not charge if test cost is more than 200rs. Not sure how to stop these illegal lab charges.
