* The Centers for Disease Control and Prevention (CDC) has established a program to standardize and improve the measurement of steroid hormones, including E2 and T, using liquid chromatography-tandem MS (LC-MS/MS). In addition, the CDC has partnered to establish postmenopausal reference ranges for T and is developing reference intervals for E2. Minimizing some of the technical limitations of the current immunoassays and MS assays should provide better and more accurate assays for patient care.
* Equilibrium dialysis combined with a MS assay is...

Understanding Your Hormones
Estradiol (E2)
A form of estrogen produced from testosterone. Important for bone health, mood, and libido.
Too high can cause side effects; too low can affect well-being.
DHT
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth,
prostate health, and masculinization effects.
Free Testosterone
The biologically active form of testosterone not bound to proteins.
Directly available for cellular uptake and biological effects.
