Update to you ladies--found a lab in Yuen Long (near where I live) they also has a branch in Tuen Mun--

It is the 健生 X-ray and health test center. They test for FSH, LH, Prolactin and Progesterone levels in a package for $1180 HKD (I think I remember the quote correctly). They are open Mon-Sat, 8 am to 6 pm. In Yuen Long they are on the Yuen Long Main Street 162-168, 3rd floor, E and can be reached at 2476-8583. Their weekday receptionist speaks English well--is young and friendly. No prescription needed and they offer a full range of tests including health screenings for travel abroad, full body checkups, MRI etc. These places are all around in HK, it seems--no appointment needed--walk in, tell them what you need tested--show your ID and pay. Just wanted to update for those who may need the same thing. This is exactly what I need because my doctor in the States will just read the results and we'll go from there. Thanks so much for your input as well!
