A blood pressure medication may be started without any blood work potentially. It is mainly going to be determined as to your baseline blood pressure ...if average BP is above 135/85 ( seated / resting and Best to include outside doctor's office readings ) in doctors office a single mildly elevated reading such as 140 / 90 alone should not trigger a start of treatment

It is best and more thourough to include some blood work to look in particular at renal function ( BUN/ creatinine ) and electrolytes --- sodium, potassium , calcium , bicarbonate , chloride....

You will see some varied approaches that may include more early blood work in some cases but it is not the first priority ...

Using a diuretic would be more an indication to get baseline labs ...

Very high blood pressure would be more likely to prompt more extensive work up ...
