I'm not an expert on this so I would contact the facility where you had the test done to ask but I found this and think it might help you:
"The antral follicle count records the number of visible ovarian follicles (210 mm mean diameter) that are observed during transvaginal ultrasonography in the early follicular phase (cycle days 25). The number of antral follicles correlates with the quantity of remaining follicles and with the ovarian response during controlled ovarian stimulation, and good intercycle and interobserver reliability has been demonstrated (9, 17). A low antral follicle count is considered 36 total antral follicles and is associated with poor response to ovarian stimulation during IVF, but it does not reliably predict failure to conceive; in a meta-analysis, a low antral follicle count was a mean of 5.2 (2.11 standard deviation) total antral follicles (9). There are limited data on the predictive capacity of antral follicle count for IVF patients, so it should not be the sole criterion used to plan treatment (1). When antral follicle count was compared with age, basal FSH, basal estradiol, antimüllerian hormone, inhibin B, and ovarian volume, antral follicle count and antimüllerian hormone were the most significant predictors of poor response to ovarian stimulation but were not predictive of failure to conceive (17)."

Hope this helps! I would really encourage you to call where you had the test done!
