Less likely: Where do you live that you're using SI units? Always ask for lab's normal reference range for particular test result b/c different ways of measuring can lead to different results. In fact, there are at least 3 different ways to measure testosterone. Given that your T is most likely at low end of normal, you're slim w/o acne &amp; have regular menses, your hirsutism is unlikely to be due to PCOS.

Check out reference ranges: http://www.healthline.com/health/low-testosterone/testosterone-levels-by-age#Adolescence3 & http://www.mayomedicallaboratories.com/test-catalog/Clinical+and+Interpretive/83686. Then use http://www.globalrph.com/conv_si.htm to convert to SI units. I hope you don't mind me poking about SI units. We're Luddites when it comes to units of measure.
