Like is stated above... they will be looking for a sample that's at least 3\4 of an inch long. Bash, if you have chest hair I would shave it so that they will be forced to take it from your armpits. Now that sample... unless you shave or trim regularly it will be at least 1 inch long giving you a longer cleaner sample for the test.
