Blood Spot Testing

Blood Spot is the future of blood testing and is a convenient form of health and wellness testing.  The development and application of blood spot testing allows monitoring of hormone levels, cardiometabolic markers and Vitamin D.  The convenient collection of blood from a tiny nick of the finger, allows for flexibility of testing at the right time of day, month or following hormone therapy.  Blood Spot testing provides results on par with those from serum tests but without the cost and inconvenience of conventional blood draws, making it beneficial for both patient and practitioner.
