General Practitioner Questions Blood levels

What type of test is this?

I have an evaluation I privately am paying for. They ordered a 5+Etg+Crt-Scr . I am deathly afraid of needles so I just wanted to know if this is a blood test or a urinalysis so I know how to prepare.

Blood for allergy
According to my quick search, the 5+Etg+Crt-Scr is a urine test for drug and alchohol traces in your body. Why are you doing this?
