The Thyroxine - Total (T4) test measures both the bound and unbound/free form of thyroxine (T4) hormone in the blood. T4 exists in the blood in two forms: bound (attached to proteins) and free (not attached to proteins). Most of the T4 circulating in the blood is bound to proteins and only a small part is free. It is necessary to maintain a fine balance of these forms to ensure the proper functioning of the body.

The Triiodothyronine - Total (T3) test measures triiodothyronine, also known as T3, hormone that is produced by the thyroid gland. T3 hormone plays an important role in regulating the body's metabolism, energy levels, and growth & development. It exists in the blood in two forms: free T3 and bound T3. Free T3 is not bound to proteins in the blood and is the active form of T3. Whereas, bound T3 is bound to proteins, such as albumin and thyroid hormone binding globulin (THBG), which prevent it from entering the body tissues.

The TSH (Thyroid Stimulating Hormone) Ultrasensitive test measures the levels of TSH hormone in the blood. TSH is produced by the pituitary gland located at the base of the brain. Its function is to stimulate and regulate the functioning of the thyroid gland. It signals the thyroid gland to increase or decrease the production of thyroid hormones T3 and T4 when their levels are low or high, respectively. Therefore, when the levels of T3 & T4 decrease, the pituitary gland is stimulated to release TSH. This high TSH level, in turn, stimulates the thyroid gland to release more thyroid hormones (T3 & T4). Vice versa happens when the levels of thyroid hormones increase.

What Do Normal TSH (Thyroid Stimulating Hormone) Ultrasensitive Levels Mean?

Normal TSH levels indicate that your thyroid is functioning well, producing the right amount of thyroid hormones (T3 and T4) to regulate metabolism, energy, and overall body functions. Balanced TSH suggests your body is maintaining proper hormonal balance, supporting healthy weight, energy levels, mood, and cardiovascular health.

What Do High Levels of TSH (Thyroid Stimulating Hormone) Ultrasensitive Indicate?

High TSH levels usually mean the thyroid is underactive (hypothyroidism). The pituitary gland releases extra TSH to make the thyroid produce more hormones.

Common causes include:

• Autoimmune thyroid problems like Hashimoto’s thyroiditis
• Pituitary gland disorders
• Recovery after illness or thyroid surgery
• Some medicines or a lack of nutrients

What to Do if Your TSH (Thyroid Stimulating Hormone) Is Higher Than Normal?

If your TSH level is high, talk to your doctor. They may: 

• Recheck with more thyroid tests (T3, T4, or antibodies)
• Review your medicines, diet, and health history
• Recommend thyroid hormone treatment if required
• Track symptoms like tiredness, weight gain, feeling cold, or hair loss

Timely management can help control thyroid imbalances effectively.

What Do Low Levels of TSH (Thyroid Stimulating Hormone) Ultrasensitive Indicate?

Low TSH levels usually mean your thyroid is overactive (hyperthyroidism). This happens when the thyroid releases excess thyroid hormones, so the pituitary gland reduces TSH production.

Possible causes include:

• Graves’ disease (autoimmune thyroid disorder)
• Thyroid nodules that produce extra hormones
• Thyroid inflammation (thyroiditis)
• Taking too much thyroid medicine

If your TSH is low, your doctor may suggest more tests like T3, T4, thyroid antibody tests, or an ultrasound to find the cause and decide the right treatment.

Can TSH Results Be Inaccurate?

Yes. Certain factors such as pregnancy, recent illness, medications, or underlying pituitary or thyroid disorders can affect TSH levels and lead to inaccurate results. If your results do not match your symptoms or overall health, your doctor may suggest repeating the test or additional testing. 

What Factors Can Affect TSH (Thyroid Stimulating Hormone) Ultrasensitive Results?

The TSH (Thyroid Stimulating Hormone) Ultrasensitive test is reliable, but a few factors can affect its accuracy, such as:

• Recent thyroid surgery or radioactive iodine treatment
• Taking biotin supplements
• Severe illness or hospitalization
• Certain medicines (like amiodarone or lithium)
• Pregnancy

What Follow-Up Tests May Be Required?

Based on your TSH results, your doctor may suggest more tests to better understand your thyroid health. These tests may include:

How Does TSH Test Differ from Other Thyroid Tests?

It is important to understand how the TSH test differs from other common thyroid tests:

TSH (Thyroid-Stimulating Hormone): Measures how much signal the pituitary gland is sending to the thyroid to make hormones.

Total T4: Measures the overall amount of thyroxine (T4) in the blood, including both bound and unbound forms, to understand thyroid hormone production.

Free T4 (FT4): Checks the active form of T4 that is available for use by the body. It helps assess how well the thyroid is functioning.

Total T3: Measures the total amount of triiodothyronine (T3), the active hormone derived from T4, often helpful in detecting hyperthyroidism.

Free T3 (FT3): Evaluates the unbound, active T3 level to understand how efficiently T4 is being converted to T3.

Thyroid Antibody Tests (TPOAb, TgAb): Identify autoimmune thyroid conditions like Hashimoto’s thyroiditis or Graves’ disease.

There are five types of WBCs: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. A Differential Leukocyte Count test measures the percentage of each type of WBC in the blood. Leukocytes or WBCs are produced in the bone marrow and defend the body against infections and diseases. Each type of WBC plays a unique role to protect against infections and is present in different numbers.

The Red Blood Cell Count test measures the total number of red blood cells in your blood. RBCs are the most abundant cells in the blood with an average lifespan of 120 days. These cells are produced in the bone marrow and destroyed in the spleen or liver. Their primary function is to help carry oxygen from the lungs to different body parts. The normal range of RBC count can vary depending on age, gender, and the equipment and methods used for testing.

The Hb (Hemoglobin) test measures the concentration of hemoglobin in your blood. Hemoglobin binds oxygen molecules and carries them to body tissues while removing carbon dioxide. Low hemoglobin suggests reduced oxygen-carrying capacity. It can be due to anemia, bleeding, nutritional deficiencies (iron, vitamin B12, folate), or chronic disease. High hemoglobin may occur in dehydration, living at high altitudes, smoking, or diseases like polycythemia vera.

Pathological Factors 

The Platelet Count test measures the average number of platelets in the blood. Platelets are disk-shaped tiny cells originating from large cells known as megakaryocytes, which are found in the bone marrow. After the platelets are formed, they are released into the blood circulation. Their average life span is 7-10 days. 

Platelets help stop the bleeding, whenever there is an injury or trauma to a tissue or blood vessel, by adhering and accumulating at the injury site and releasing chemical compounds that stimulate the gathering of more platelets. A loose platelet plug is formed at the site of injury and this process is known as primary hemostasis. These activated platelets support the coagulation pathway that involves a series of steps, including the sequential activation of clotting factors; this process is known as secondary hemostasis. After this step, there is a formation of fibrin strands that form a mesh incorporated into and around the platelet plug. This mesh strengthens and stabilizes the blood clot so that it remains in place until the injury heals. After healing, other factors come into play and break the clot down so that it gets removed. In case the platelets are not sufficient in number or not functioning properly, a stable clot might not form. These unstable clots can result in an increased risk of excessive bleeding. 

The Total Leukocyte Count test measures the numbers of all types of leukocytes, namely neutrophil, lymphocyte, monocyte, eosinophil, and basophil, in your blood. Leukocytes or WBCs are an essential part of our immune system. These cells are produced in the bone marrow and defend the body against infections and diseases. Each type of WBC plays a unique role to protect against infections and is present in different numbers.

The Hematocrit test measures the proportion of red blood cells (RBCs) in your blood as a percentage of the total blood volume. It is a crucial part of a complete blood count (CBC) and helps in assessing your blood health. RBCs are responsible for carrying oxygen from the lungs to different parts of the body. The hematocrit test provides valuable information about your blood's oxygen-carrying capacity.

Higher-than-normal amounts of RBCs produced by the bone marrow can cause the hematocrit to increase, leading to increased blood density and slow blood flow. On the other hand, lower-than-normal hematocrit can be caused by low production of RBCs, reduced lifespan of RBCs in circulation, or excessive bleeding, leading to a reduced amount of oxygen being transported by RBCs. Monitoring your hematocrit levels is essential for diagnosing and managing various blood-related disorders.

The Mean Corpuscular Volume test measures the average size of your red blood cells, which carry oxygen through your body. This test tells whether your RBCs are of average size and volume or whether they are bigger or smaller.

An MCH test measures the average amount of hemoglobin in a single red blood cell (RBC). Hemoglobin is an iron-containing protein in RBCs, and its major function is to transport oxygen from the lungs to all body parts. This test provides information about how much oxygen is being delivered to the body by a certain number of RBCs.

An MCHC test measures the average amount of hemoglobin in a given volume of RBCs. MCHC is calculated by dividing the amount of hemoglobin by hematocrit (volume of blood made up of RBCs) and then multiplying it by 100. 

The Absolute Leucocyte Count test measures the total number of white blood cells (leucocytes) in the given volume of blood. It examines different types of white blood cells such as neutrophils, lymphocytes, monocytes, basophils and eosinophils. These cells tell about the status of the immune system and its ability to fight off infections and other conditions like inflammation, allergies, bone marrow disorders etc.

An MPV test measures the average size of the platelets in your blood. Platelets are disk-shaped tiny cells originating from large cells known as megakaryocytes, which are found in the bone marrow. After the platelets are formed, they are released into the blood circulation. Their average life span is 7-10 days. 

Platelets help stop bleeding whenever there is an injury or trauma to a tissue or blood vessel by adhering and accumulating at the injury site, and by releasing chemical compounds that stimulate the gathering of more platelets. After these steps, a loose platelet plug is formed at the site of injury, and this process is known as primary hemostasis. These activated platelets support the coagulation pathway that involves a series of steps including the sequential activation of clotting factors; this process is known as secondary hemostasis. After this, there is a formation of fibrin strands that form a mesh incorporated into and around the platelet plug. This mesh strengthens and stabilizes the blood clot so that it remains in place until the injury heals. After healing, other factors come into play and break the clot down so that it gets removed. In case the platelets are not sufficient in number or are not functioning properly, a stable clot might not form. These unstable clots can result in an increased risk of excessive bleeding. 

The PDW test reflects variability in platelet size, and is considered a marker of platelet function and activation (clot formation in case of an injury). This marker can give you additional information about your platelets and the cause of a high or low platelet count. Larger platelets are usually younger platelets that have been recently released from the bone marrow, while smaller platelets may be older and have been in circulation for a few days. Higher PDW values reflect a larger range of platelet size, which may result from increased activation, destruction and consumption of platelets.

The RDW CV test which is part of red cell indices, helps identify characteristics of red blood cells. RDW (red cell distribution width) measures the variations in the sizes of red blood cells, indicating how much they differ from each other in a blood sample. RDW is expressed as RDW-CV, a coefficient of variation. A higher RDW may suggest more variation in red cell sizes, while a lower RDW indicates more uniform red cell sizes.
