I can understand your concern.
Since you say that you are healthy, I'm assuming you are not suffering from any medical illness be it genetic or acquired.
You can go to a general physician and get your blood pressure checked out but I do not feel that you might require any blood tests.
Have a healthy diet, exercise daily and drink lots of water daily ,you will be healthy.
In conclusion- no harm in getting your blood pressure checked out on a regular basis but until any abnormality is detected, no blood tests required.

Send more details like height, weight, job, parental medical issues, any past medical issues....will decide suitable test package...but general basic health package with thyroid is advised for having screening of the various body functions though there are no symptoms....
