Blood Spot Testing

ANSWERS TO QUESTIONS ABOUT BLOOD SPOT TESTING

Blood Spot testing requires only a tiny amount of blood from a nearly painless finger prick—at home. You send the sample to the lab in a prepaid container and results can be sent to you or your doctor. Several tests can be run from a single sample. Blood spot testing provides results on a par with those from serum tests (the kind that requires a prescription from your doctor and a visit to a lab) but without the cost and inconvenience. In addition, collection times can be optimized for fasting baseline hormone levels, assessment of HRT dosing and diurnal hormone testing.
