TSH

A pituitary signal used in thyroid-axis interpretation.

Views: 64

What it is

TSH is thyroid-stimulating hormone, a pituitary signal used in thyroid testing.[1]

Why it matters

It sits in a feedback relationship with thyroid hormone production, so it is often central to thyroid-axis interpretation.[1]

What it affects

  • It is interpreted with thyroid hormone measures such as free T4 in many contexts.[1]
  • It is an upstream regulatory signal, not a symptom by itself.[1]

Interpretation traps

  • Pituitary disease, pregnancy, medications, and non-thyroid illness can affect interpretation.[1]
  • BioConst does not interpret personal TSH values.[1]
