Introduction
The human body is an intricate system, and the endocrine system plays a vital role in regulating many essential functions such as metabolism, energy balance, growth, and development. At the center of the endocrine system lies the thyroid gland, a butterfly-shaped gland located in the neck. Its function is crucial, as it produces hormones that influence nearly every cell, tissue, and organ of the body.
To evaluate the function of the thyroid gland, physicians rely on Thyroid Function Tests (TFTs). These laboratory investigations measure the levels of various hormones such as TSH (Thyroid Stimulating Hormone), T3 (Triiodothyronine), T4 (Thyroxine), and in some cases thyroid antibodies. Correct interpretation of these tests allows healthcare professionals to diagnose conditions like hypothyroidism, hyperthyroidism, goiter, thyroiditis, and thyroid cancer.
For medical and paramedical students, laboratory technologists, and healthcare professionals, learning the principles, techniques, and interpretation of thyroid function tests is essential. This is why training institutes such as the HRTD Medical Institute in Dhaka, Bangladesh, play a significant role in shaping competent laboratory professionals.
This comprehensive training content will provide students with:
- A detailed understanding of thyroid physiology.
- An overview of thyroid function tests and their clinical importance.
- Step-by-step laboratory techniques.
- Training opportunities available at HRTD Medical Institute.
- Practical applications, case studies, and future career opportunities.

Chapter 1: Understanding the Thyroid Gland
1.1 Anatomy of the Thyroid Gland
- Location: Situated in the anterior part of the neck, below the Adam’s apple.
- Structure: Consists of two lobes connected by an isthmus.
- Weight: Approximately 20–25 grams in adults.
- Function: Secretes hormones that regulate metabolic activity.
1.2 Physiology of Thyroid Hormones
- T3 (Triiodothyronine): The active form of thyroid hormone that regulates metabolism.
- T4 (Thyroxine): Secreted in larger quantities but converted to T3 in peripheral tissues.
- TSH (Thyroid Stimulating Hormone): Secreted by the pituitary gland, controls thyroid hormone release.
1.3 Importance of Thyroid Hormones
- Regulation of metabolism.
- Growth and development (especially brain development in infants).
- Maintenance of body temperature.
- Influence on heart rate, weight, and energy levels.
Chapter 2: Introduction to Thyroid Function Tests
2.1 What Are Thyroid Function Tests?
Thyroid function tests are blood tests that measure hormone levels to assess how well the thyroid gland is working.
2.2 Common Tests Performed
- TSH Test: The most sensitive marker for thyroid function.
- Free T4 (FT4): Measures the active thyroxine hormone.
- Free T3 (FT3): Measures the active triiodothyronine hormone.
- Thyroid Antibodies: Useful for autoimmune disorders like Hashimoto’s thyroiditis and Graves’ disease.
- Thyroglobulin: Used in monitoring thyroid cancer treatment.
2.3 Indications for Thyroid Testing
- Symptoms of hypothyroidism (fatigue, weight gain, dry skin).
- Symptoms of hyperthyroidism (weight loss, anxiety, tremors).
- Routine screening in pregnancy.
- Follow-up of thyroid patients on treatment.
- Screening newborns for congenital hypothyroidism.
Chapter 3: Laboratory Methods for Thyroid Testing
3.1 Blood Sample Collection
- Venipuncture using sterile techniques.
- Serum separation after clotting.
- Proper labeling and storage at recommended temperature.
3.2 Methods of Hormone Estimation
- Radioimmunoassay (RIA): Traditional method using radioactive isotopes.
- Enzyme-Linked Immunosorbent Assay (ELISA): Widely used due to safety and accuracy.
- Chemiluminescent Immunoassay (CLIA): Highly sensitive and modern technique.
- Electrochemiluminescence (ECL): Gold standard in many laboratories.
3.3 Quality Control in Thyroid Testing
- Internal and external quality control samples.
- Calibration of machines.
- Avoiding sample contamination and hemolysis.

Chapter 4: Interpretation of Thyroid Function Test Results
4.1 Hypothyroidism
- High TSH, low T4.
- Symptoms: fatigue, constipation, hair loss, depression.
4.2 Hyperthyroidism
- Low TSH, high T3/T4.
- Symptoms: weight loss, nervousness, sweating, fast heart rate.
4.3 Subclinical Conditions
- Mild abnormalities in TSH while T3/T4 remain normal.
4.4 Autoimmune Thyroid Diseases
- Positive TPO antibodies in Hashimoto’s thyroiditis.
- Positive TSH receptor antibodies in Graves’ disease.
Chapter 5: Importance of Thyroid Function Test Training for Students
5.1 Why Students Should Learn TFTs
- Understanding endocrine disorders.
- Developing laboratory skills.
- Enhancing diagnostic accuracy.
- Building a foundation for careers in pathology and laboratory medicine.
5.2 Career Opportunities for Trained Students
- Laboratory technologist in diagnostic centers.
- Clinical researcher in endocrinology.
- Employment in hospitals, clinics, and medical institutes.
- Teaching and academic careers.
