1. What is Thyroid Function Testing?

Thyroid function testing measures TSH, T4, and T3 levels to evaluate thyroid gland function. These hormones regulate metabolism, energy production, and numerous bodily functions. The calculator helps interpret these values to identify thyroid disorders.

2. How Does the Calculator Work?

The calculator evaluates TSH, T4, and T3 levels against established reference ranges:

Reference Ranges:
• TSH: 0.4-4.0 mIU/L
• T4: 4.5-11.2 μg/dL
• T3: 80-200 ng/dL

The algorithm compares your values to determine thyroid status:

Hyperthyroidism: Low TSH, High T4/T3
Hypothyroidism: High TSH, Low T4/T3
Subclinical Conditions: Abnormal TSH with normal T4/T3
Euthyroid: All values within normal range

3. Importance of Thyroid Level Assessment

Details: Proper thyroid function is essential for metabolic regulation, cardiovascular health, neurological function, and overall wellbeing. Early detection of thyroid disorders allows for timely treatment and prevention of complications.

4. Using the Calculator

Tips: Enter TSH in mIU/L, T4 in μg/dL, and T3 in ng/dL. Use fasting morning samples for most accurate results. Values should be from the same blood draw for proper interpretation.

5. Frequently Asked Questions (FAQ)

Q1: What is the most important thyroid test?
A: TSH is the most sensitive screening test, but full assessment requires T4 and T3 for complete thyroid function evaluation.

Q2: Can medications affect thyroid test results?
A: Yes, thyroid medications, steroids, birth control pills, and other drugs can influence thyroid hormone levels.

Q3: How often should thyroid levels be checked?
A: For diagnosed thyroid conditions, every 6-12 months. For screening in healthy adults, every 2-5 years depending on risk factors.

Q4: What factors can temporarily affect thyroid levels?
A: Acute illness, pregnancy, recent contrast dye exposure, and certain supplements can cause temporary fluctuations.

Q5: Should this replace medical consultation?
A: No, this calculator provides preliminary interpretation. Always consult with a healthcare provider for diagnosis and treatment decisions.
