Frequently Asked Questions

What does a low T4 count show?

Hypothyroidism, which is characterized by a low T4 value, is a disorder in which the thyroid gland is underactive. Autoimmune illnesses (including Hashimoto’s thyroiditis), drug side effects, iodine shortage, radiation therapy, congenital thyroid abnormalities, and pituitary gland issues can all contribute to hypothyroidism.

What does a high T4 count show?

Hyperthyroidism, in which the thyroid gland is hyperactive, might be indicated by an elevated T4 level. Excessive T4 production and secretion are hallmarks of hyperthyroidism, which also affects the thyroid itself. Graves’ disease, toxic adenomas, and thyroiditis are typical causes of hyperthyroidism.

What does the T4 count indicate?

The term “T4 count” likely refers to the measurement of the hormone thyroxine (T4) in the blood. Thyroxine is produced by the thyroid gland and plays a crucial role in regulating the body’s metabolism, energy production, and overall growth and development. Doctors often combine T4 measurements with other thyroid tests, such as T3 (triiodothyronine) levels, thyroid-stimulating hormone (TSH) levels, and clinical evaluation to get a comprehensive understanding of a person’s thyroid health.

The quantity of CD4+ T cells in a blood sample is referred to as the T4 count, T4 lymphocyte count, or CD4 count. The immune system relies heavily on CD4+ T cells, a subset of white blood cells. They work to coordinate the body’s immunological response to pathogens. In a healthy person, the number of T4 cells per mL of blood should range from 500 to 1500.

In people with HIV/AIDS, the T4 count is frequently used as a measure of immunological health. HIV directly reduces the amount of CD4+ T cells by targeting and infecting them. T4 monitoring is useful for gauging immune function and tracking HIV disease progression.
