Risk Scale
Optimal range for SPINA-GT appears to be between 2.32 and 7.76:
0
1.41
2.32
7.76
8.67
15
Why this optimal range?
Reference range 1.41-8.67 pmol/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-GT interpretation

For low

Low SPINA-GT indicates reduced thyroid secretory capacity.

  • Primary hypothyroidism
  • Autoimmune thyroiditis (Hashimoto's)
  • Iodine deficiency
Sources

For high

Elevated SPINA-GT indicates increased thyroid secretory capacity.

  • Primary hyperthyroidism
  • Graves' disease
  • It has been observed to positively correlate to resting energy expenditure, resting heart rate, the colour Doppler ultrasound pattern and thyroid volume.
