How do you write transfer letter to a special unit in the hospital?

Using a standard business letter format (link below), state your request and any specifications as your first paragraph, 'I am writing to request...'

Use the second paragraph to explain the reasons (s) for the request, keeping it short and to the point. Mention or list anything that may be attached to support your request.

Start the third paragraph with any important dates or time frame, if applicable; next provide the information necessary for them to contact you; and the last sentence is used to thank them for their time or their action.

That's all you need.
