Different tests require different volumes of blood. When you go into a Quest or Labcorp location and a phlebotomist conducts an intravenous (IV) blood draw, that oftentimes requires more blood than at-home testing kits that utilize different testing methodologies. Our lab partner, Tasso, uses a state-of-the-art device that requires less blood than a typical IV blood draw. You can read more information about their technology at https://www.tassoinc.com/
