1. What is T3 Unit Conversion?

T3 (triiodothyronine) unit conversion between nmol/L (nanomoles per liter) and ng/dL (nanograms per deciliter) is essential for standardizing thyroid function test results across different laboratory reporting systems and clinical guidelines.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

\[ ng/dL = \frac{nmol/L \times 650.44}{10} \]

Where:

\( nmol/L \) — T3 concentration in nanomoles per liter
\( 650.44 \) — Molecular weight of T3 (g/mol)
\( 10 \) — Conversion factor for volume units
\( ng/dL \) — Result in nanograms per deciliter

Explanation: The formula accounts for molecular weight and unit conversion between concentration measurements.

3. Importance of T3 Measurement

Details: T3 is the active thyroid hormone that regulates metabolism, growth, and development. Accurate measurement and standardized unit reporting are crucial for diagnosing thyroid disorders including hyperthyroidism and hypothyroidism.

4. Using the Calculator

Tips: Enter T3 value in nmol/L. The value must be a positive number. The calculator will automatically convert to ng/dL using the standard conversion formula.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between nmol/L and ng/dL?
A: Different laboratories and countries use different units. Conversion ensures consistent interpretation of thyroid function test results across healthcare systems.

Q2: What is the molecular weight used in conversion?
A: The conversion uses 650.44 g/mol, which is the molecular weight of triiodothyronine (T3).

Q3: What are normal T3 values?
A: Normal ranges vary by laboratory but typically range from 1.2-3.1 nmol/L or 80-200 ng/dL in adults. Always consult specific laboratory reference ranges.

Q4: When should T3 levels be measured?
A: T3 testing is indicated when thyroid dysfunction is suspected, particularly when T4 and TSH results are discordant or when hyperthyroidism is suspected.

Q5: Are there limitations to unit conversion?
A: While the conversion is mathematically precise, clinical interpretation should always consider the specific assay method and patient context, as different assays may have varying specificities.
