Collection Timing Matters for Urine Testing

Posted by Ben White on

By Dr. Kate Placzek ZRT Laboratory Urine is rapidly becoming the preferred medium for neurotransmitter testing to ensure objective neurobiological assessment. This is because a) urine is the primary route of peripherally-produced neurotransmitter elimination; and b) it is non-invasive and cost-effective. This blog takes a look at how dried urine testing provides a superior advantage over standard liquid urine collection methods. Is a 24-hour collection necessary – or even desirable? The gold standard of neurotransmitter testing in urine involves an inconvenient and mildly embarrassing collection of liquid urine over a period of 24 hours into a jug. The awkwardness of...

Testing Methods and Safety

Posted by Ben White on

The current concern over the dangerous Ebola virus has heightened awareness about infections that can be transmitted via contact with body fluids. The last thing we want is to be exposed to body fluids from others infected with dangerous organisms and, ironically, a likely place to encounter such fluids is the phlebotomy station at the doctor’s office. How can exposure to other people who may be sickened with an infectious agent be minimized? One way to minimize exposure is to use at-home sample collection methods, a hallmark of ZRT lab testing, which ensure seclusion and don’t require samples to be...

Cortisol Hormone Testing in Saliva, Blood & Urine

Posted by Ben White on

Hormone Test Providers should be aware that three different body fluids – saliva, blood or urine – can be used to assess adrenal gland function, and should know each method’s advantages and disadvantages, when deciding how to test patients. Inadequate or excessive production or disrupted circadian patterns of cortisol synthesis by the adrenal glands in response to stressors can eventually lead to imbalances in blood glucose levels, impaired immune response, as well as a host of different hormonal imbalances, all of which are associated with multiple adverse conditions and symptoms.    Saliva   Cortisol is synthesized by the adrenal glands and released into the bloodstream in...
