Specializes in Endocrinology

Most women gave detectable testosterone if measured properly with a sensitive test. Comes from adrenal mostly. Not related to Vit D unless a high dose interferes with assay. Also taking biotin will lower some and increase other ENDO tests so tell your Dr everything you are taking.ALWAYS.

lab values can vary in this range. Why are you taking high dose vit D? If you eat a healthy diet you do not need any 'high dose 'supplements as they can cause hypervitaminosis.
