    ZRT Laboratory Announces New Iodine Test in Dried Urine

    FOR IMMEDIATE RELEASE – download pdf.

    Portland, Oregon, 12/20/2010 - Following a lengthy amount of research and development, ZRT Laboratory has introduced an innovative diagnostic test for measuring Iodine levels.  This important test will be done in dried urine, which is a new, totally non-invasive technology developed by ZRT Laboratory.

    Current scientific literature points to a significant amount of evidence that large numbers of the population may be deficient in Iodine.  This growing concern is important to address, as Iodine is pivotal to the normal function of the thyroid gland, in addition to the health and integrity of breast tissue.  In many instances, symptoms of hypothyroidism, fibrocystic breasts, fatigue and brain fog may actually be diagnosed as something other than Iodine deficiency, when in fact it could be the primary cause of these conditions.

    Until now, collection of a sample to test Iodine levels has required a 24-hour urine collection that includes utilizing a bulky container to store the sample. To overcome this inconvenience to a patient and practitioner, ZRT developed and refined Iodine testing in a dried urine collection.  This method takes just a few minutes to collect urine on a filter strip two times a day.  The specimen is then sent to ZRT for analysis of the Iodine content.  Iodine levels determined in extracts of urine dried on filter paper are quantitatively equivalent to measurements in wet urine. ZRT utilizes what is known as the Sandell-Kolthoff method for its calculations, which shows highly significant correlations with ICP-Mass Spectrometry.

    ZRT Laboratory participates in the CDC-sponsored EQUIP (Ensuring the Quality of Iodine Procedures) iodine standardization program, where multiple urine samples are tested for Iodine content and compared with values generated by ICP-MS at CDC and other laboratories performing iodine testing around the world (results available on request).
