The Iodide QFA 1500 is an instrument that precisely measures iodide concentrations in body fluids. The instrument can be used to measure iodine in body fluids for many physiological purposes and has significance depending on the application. The analyzer will very accurately report iodide residuals to give the practitioner:
Iodine in saliva as an indirect measurement of the interstitial iodine concentration level.
Iodine in whole blood as an indirect measurement of the sodium/iodine symporter efficiency.
Iodine in urine as an indicator of the body’s iodine sufficiency.
The reason practitioners care about iodine residuals is the thyroid’s need for iodine to produce the hormones T4 eventually T3 that regulate metabolism. Because of the lack of iodine in the western diet, many people are hypothyroid and exhibit many of the symptoms of this condition. Measuring iodine does not diagnose hypothyroidism, that is the practitioner’s expertise, but does measure iodine supplementation progress.
