Blood spot is ideal for measuring hormones and other analytes such as insulin, blood lipids, Vitamin D, thyroid hormones, and elements like lead and magnesium. It offers distinct advantages over serum because it eliminates the need for a blood draw – saving patients time and money.
ZRT developed the science for accurately measuring hormones in dried blood spot and is currently one of the only labs to offer this method commercially.
ZRT’s convenient blood spot collection eliminates blood draw needles, blood draw fees and the need to see a phlebotomist. Patients can collect their sample at home at the time that suits them. Research also shows that blood spot is more accurate than serum for measuring blood hormone levels in patients supplementing topically.
