It depends on the testing method. You have to ask your testing center.
Latest advanced testing methods needs a period of 60 days.
That is the Control group.

The group that is exposed to the variable being tested in an experiment is called the experimental group. This group is compared to the control group, which is not exposed to the variable, in order to determine the effect of the variable on the outcome being measured.
This is known as the experimental group.
This is known as the experimental group.
Experiments typically involve:1) Experimental group: the group of subjects exposed to the variable being tested.2) Control group: should be as identical as possible to the experimental group, but is deliberately not exposed to the experimental variable - this provides a baseline measure from which the effect of the variable can be determined.

No they do not, i have gotten prescribed many controlled substances without being tested
The group in an experiment that is exposed to the factor being tested is called the experimental group. This group is subjected to the treatment or intervention being studied to observe its effects, while the control group is used as a baseline for comparison. Comparing results between the experimental and control groups helps researchers determine the impact of the factor being tested.

A test group in biology refers to the group being experimented on or tested in a study. It is the group that is exposed to the variable being tested, allowing researchers to compare its outcomes to those of the control group, which is not exposed to the variable. This experimental design helps researchers determine the effect of the variable being studied.
