Basically, when you get your results, if you see your levels on the left and the standard ranges on the right, those ranges are usually broken down by specific cycle phases. So, I guess you just look for the value that matches your current phase to find your baseline.
At least, that’s how my lab reports looked, and neither of my doctors actually told me specifically when I should go in.
I suppose you can test any time if it isn't an emergency; it's pretty easy enough to adjust the math. But some hormones are only at their baseline for about three to five days, so it might be easier to catch if they're elevated during that window. Honestly, nobody wants to deal with the headache of recalculating everything, and some tests are just more reliable that way. Every hormone fluctuates throughout the cycle—they aren't constant. They rise and fall naturally. It just depends on what you're trying to catch and when. Your OB-GYN probably knows best what they want to see.
I had to go during that three-to-five-day window myself. I think it was for FSH, LH, and androgens, though I'm not entirely sure.
