Component

Dried-blood-spot thyroglobulin concentration

Dried-blood-spot thyroglobulin concentration. Study-specific scope and measurement methods are recorded with each claim.

2 recorded relationships. Experimental role, claim status and evidence remain attached to each record.

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it acts on

  1. The third and 97th percentiles of the standardized dried-blood-spot Tg assay were 4 and 40 micrograms/L in the 700 iodine-sufficient, euthyroid, anti-Tg-negative children.

What acts on it

  1. Median dried-blood-spot thyroglobulin fell from 49 to 13 and 8 micrograms/L at 5 and 10 months after iodized salt introduction; proportions above 40 micrograms/L fell from over two thirds to 7% and 3%.
