• Regulate metabolism
• Control body temperature
• Manage heart rate
• Support energy production
• Influence brain development
• Maintain muscle and digestive functions

Normal Ranges Typical Reference Ranges:

• TSH: 0.4 to 4.0 mIU/L
• Free T4: 0.8 to 1.8 ng/dL
• Total T3: 80 to 180 ng/dL

Test Limitations Potential Interference Factors: • Medications • Pregnancy • Age variations • Stress levels • Laboratory testing methods • Individual metabolic differences

Low Results May Indicate Potential Conditions:

• Hyperthyroidism
• Overactive thyroid
• Excessive hormone production
• Potential autoimmune disorders

High Results May Suggest Potential Conditions:

• Hypothyroidism
• Underactive thyroid
• Insufficient hormone production
• Potential pituitary gland issues
