SPINA-GD ranges

According to Dietrich et al. (2016), SPINA-GD should be between 20 and 60 nmol/s:

Why this optimal range?
Reference range 20-40 nmol/s as defined in SPINA-THYR software.
Ranges in red are: ±2xSD from the mean, ranges in yellow are ±1.5-2xSD from the mean.

SPINA-GD interpretation

What a low value may mean:

Low SPINA-GD indicates reduced peripheral T4-to-T3 conversion.

Sources

What a high value may mean:

High SPINA-GD indicates increased peripheral T4-to-T3 conversion.
