Standard Tests

Saliva, blood spot and dried urine are used for the minimally-invasive hormone testing that is the hallmark of ZRT Laboratory.  The simplicity of sample collection and stability of samples in storage and transport have made these ideal for clinical use as well as research.  See the table below for a full list of our current test offerings.
