A normal TSI score typically indicates a healthy thyroid stimulating immunoglobulin level. Based on standard interpretations, a normal TSI score is defined as less than 1.3, or 130 percent.
Understanding TSI Test Results
TSI (Thyroid Stimulating Immunoglobulin) test results are crucial for diagnosing and monitoring certain thyroid conditions, particularly Graves' disease. These results are commonly reported in one of two formats:
- TSI Index: This is a dimensionless ratio.
- Percentage: This represents the level as a percentage.
What is Considered Normal?
For most diagnostic purposes, specific thresholds are used to determine if TSI levels are within the normal range. As referenced, a healthy or normal TSI score falls into the following parameters:
- TSI Index: Less than 1.3
- Percentage: Less than 130%
This indicates that the levels of thyroid-stimulating immunoglobulins are not elevated to a degree that would typically suggest an autoimmune thyroid condition.
Normal TSI Score at a Glance
For quick reference, the normal ranges for TSI scores are summarized in the table below:
| Score Type | Normal Range |
|---|---|
| TSI Index | Less than 1.3 |
| Percentage | Less than 130% |
Understanding these normal ranges helps individuals and healthcare providers interpret test results effectively and determine if further investigation or monitoring is needed.
