31 y.o.with excessive hair loss,acne,and oily skin

Patient: I’m 31 years old female, I’ve been battling acne since I was a teenager, now my acne is less severe, but my face is extremely oily, my sebaceous glands are hyperactive, but what is bothering me is the hair loss, my hair is so thin and fragile, I also have excessive body hair, my MC is regular, I truly believe I have some endocrine disease.My question is what hormonal tests I should take ?Thanks
