When to Get Tested?
When your doctor thinks that you have symptoms of a hormone imbalance, abnormal vaginal bleeding, unusual and/or early sex organ development (female), or when your doctor wants to monitor the health of your placenta and fetus during pregnancy
Sample Required?
A blood sample drawn from a vein in your arm, a 24-hour urine sample, or (in some cases) a fresh saliva sample
