Blood Spot testing is the future of blood testing. The process requires only whole capillary 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.

Tests offered in the Blood Spot Profiles include: 

• Thyroxine (T4), free
• Triiodothyronine (T3), free
• Thyroid Stimulating Hormone (TSH)
• Thyroid Peroxidase Antibodies (TPO)
• Testosterone, total
• Sex Hormone Binding Globulin (SHBG)
• Prostate Specific Antigen (PSA)
• Insulin-like Growth Factor (IGF-1)
• Estradiol (E2)
• Progesterone (Pg)
