If I work a night schedule, what's the best time to get my testosterone checked?

So, I'm going in for blood work soon and my doctor said I should go in first thing in the morning around 8 or 9am. My only concern is I work nights, so my "morning" is usually around 1pm. I told them this, but they said no, still come in for 8 or 9. I'm just wondering if this will affect my results because I'll basically be waking up right in the middle of my "night" when I get up to go in for the test. Let me know what y'all think. Thanks.
