Question on Blood Test.

Parents are going to blood and urine test me for sure tomorrow at a doctors. Last time i smoked was yesterday, I was wondering if im going to show up for the blood test as positive. Ill be using quick fix for the urine. Prefer advice from past experiences because most of the internet has different durations for passing.

and what specifically are they testing for in blood test? Just active THC or metabolites too? if both will i show up positive for either one

also are there cutoffs for the levels in blood? if so, what is it? and whats the procedure for blood testing? Do they use something similiar to a dip stick?
