We already have had our Cholinesterase Specimen Exchange Scheme running for some time, but we are now opening this up for a much wider range of analytes across a range of matrices including Salivary Cortisol, Salivary Cortisone, Salivary Testosterone, Salivary 17-OH Progesterone and Serum Prednisolone.

This is a true community collective product. You have to contribute your own Specimens to become part of the service but all the data is presented in our familiar house-style with occasional added commentaries for that extra value added component.
