How To Test Iodine. The most useful test for our purposes is the urinary iodine to creatinine ratio. Please note that this is NOT the same as urinary iodine or 24-hour urinary iodine. The amount of iodine in our urine varies greatly. The readings are more helpful when we compare them against a kidney protein called creatinine.

The analyses by test method showed that among the studies which used the China Joint Raven's test, the intelligence level of children in the high iodine group was 0.86 points lower than in the control group (P>0.05).
China implemented universal salt iodization (USI) regulations to prevent IDDs in 1996, involving all 31 provinces of mainland China. In 2011, the standard of salt iodization concentration in China was adjusted to salt iodine content of 20–30 mg/kg, and provinces were allowed to choose salt iodization concentrations according to local conditions.
Urinary iodine concentrations for determining iodine status in populations Background An estimated 35% of the world's population has insufficient iodine intake (1) and continues to live at risk for iodine deficiency and associated iodine deficiency disorders. Iodine deficiency poses a threat throughout the life-
More than 90% of dietary iodine eventually appears in the urine. Thus, the urinary iodine concentration (UIC) is an excellent biomarker of recent iodine intake . The iodine status of the general population in China has been optimal in recent years, with an average UIC of 197 µg/L . In 2012, a new national decree (GB-26878-2011) for salt ...

Objective: To investigate the iodine nutrition status of the susceptible population after stop supplying iodized salt and discuss whether there is iodine nutritional status difference in different populations in high-iodine areas in China. Methods: Spot investigation methods were being used, 371 children, 506 adults and 210 cases of pregnant women during the third trimester were …
Background In spite of the salt iodization, iodine deficiency disorders (IDD) have not been sustainably eliminated in China. There are coastal areas with low iodized salt coverage rates (iodine nutrition is inadequate) and other areas with excessive amounts of iodine in the drinking water. Objective This study aimed to clarify the association of iodine deficiencies resulting from …
According to the observation the food sample or the potato slice turned to blue-black on adding the iodine solution. This proves the presence of starch in the given plant source. This was a simple experiment which is used to check for …

Aim: To test and enrich the theory of "U-curve" relationship between UI and GP. Subjects and methods: Based on the Chinese national IDD surveys (1999, 2002, 2005), the High Water Iodine survey of 2005, and the High Risk endemias survey of 2007, this article analyzed the relationship between UI and GP. The UI was grouped according to the World ...

Iodine is safe for most humans at a range of 50 – 200 mcg/day or 150 – 250 mcg/day for pregnant/nursing women. Those who do not have and are not prone to thyroid disease can occasionally tolerate higher doses. Regulating iodine can reverse Hashi, Hypo, and SCH. The levels that do this is 50 – 100 mcg per day57,58,59.
