Hello, being investigated for pcos, have a raft of blood tests to take and I’ve managed to find the optimal time in cycle suggested for each except androstenedione, does anyone know what day of your cycle you’re supposed to test this and whether AM or PM is best? I can’t ask my gp as he just gave me all the tests on one blood test form and I had to point out to him that these hormone tests are supposed to be taken on different days of my cycle to get accurate results.
