Is It Right To Call HR Regarding Status Of Interview

Hello All,
I was going through this forum from last week and i found really helpful answers to some of my questions.
I attended an Interview one week ago and the result is pending
The Interviewer said that HR will get back to me once they finalize.
Its been a week i did not get any call or mail.
what can be the right approach to call HR and ask regarding the status of Interview - is it through mail or call her on phone.
how should i start the conversation.
Help really appreciated.
Thanks
Hari

Hi,
They are not select u for that particular post. this is one thing.
or the HR forgot regarding that matter. First u mail to that respective person and then no reply to call directly..........
Best of Luck.
