Blood Spot Testing

Blood Spot Testing
Blood Spot testing is the future of blood testing. The process requires only blood from a nearly painless finger prick and several tests can be run from a single sample. Blood spot testing provides results on a par with those from serum tests but without the cost and inconvenience of conventional blood drawing.  In addition, collection times can be optimized for fasting baseline hormone levels and assessment of HRT dosing and diurnal hormone testing.
