Aging Tests: Telomeres, Free Radicals, Antioxidant Capacity, and NK Cells

Learn how to measure your biological age and immune health through telomere, free radical, and NK cell activity tests at Hanaro Medical Foundation.

Aging Tests: Telomeres, Free Radicals, Antioxidant Capacity, and NK Cells

Aging Tests - Telomeres, Free Radicals, NK Cells

Hello. This is Hanaro Medical Foundation, your health checkup center in Jongno and Gangnam.

While everyone gets a year older every year, our biological age varies from person to person. This is because the rate of aging changes depending on lifestyle habits. Recently, there has been growing interest in ‘slow aging.’ To keep your body young, it is important to understand your current state of aging. This physical aging rate can be identified through telomere, free radical and antioxidant capacity, and NK cell tests. Today, Hanaro Medical Foundation will guide you through these ‘aging tests.’

Is the Rate of Aging the Same for Everyone?

Physical aging is influenced by lifestyle habits such as diet, exercise, and sleep. Physical aging does not simply mean getting older; it can be the root cause of various chronic diseases, including cancer, cardiovascular diseases, dementia, hypertension, and diabetes.

Therefore, identifying and managing risk factors in advance through aging tests can be a great help in maintaining a healthy and vibrant life.

Aging & Immunity Test ① Telomere Test

Telomeres are repetitive nucleotide sequences at the ends of chromosomes that protect DNA. Every time our body’s cells divide, the telomere length shortens slightly. When they shorten below a certain level, the cells can no longer divide. In other words, as telomere length shortens, physical aging accelerates. Telomere length can be measured through a blood test.

Aging & Immunity Test ② Free Radical and Antioxidant Capacity Test

Free radicals are unstable substances naturally produced during the process of cells generating energy. If free radicals increase beyond what is necessary, they cause cell damage and can increase the risk of cancer or chronic diseases. The power to suppress this is called antioxidant capacity. To maintain health, it is important to keep a balance between free radicals and antioxidant capacity.

Aging & Immunity Test ③ NK Cell Activity Test

NK cells (Natural Killer Cells) are immune cells that find and destroy virus-infected or abnormal cells. What matters most with NK cells is their ‘activity.’ If NK cell activity is low, they cannot properly distinguish abnormal cells, leading to weakened immunity and an increased risk of various diseases. Therefore, you can check your body’s potential immunity through an NK cell activity test.

Frequently Asked Questions

Why is an aging test necessary?

An aging test helps to understand the body's aging status and proactively manage risk factors for various chronic diseases such as cancer, cardiovascular disease, and dementia. This allows you to maintain a healthy and vibrant life.

What items are included in the aging test?

Aging tests typically include telomere testing, reactive oxygen species and antioxidant capacity testing, and NK cell activity testing. These tests can confirm the speed of physical aging and immunity.

What does the telomere test check?

The telomere test measures the length of telomeres at the ends of chromosomes. As telomere length shortens, cell division stops and physical aging accelerates, so this test can predict the rate of aging.

Why are reactive oxygen species and antioxidant capacity tests important?

Reactive oxygen species can cause cell damage, increasing the risk of cancer and chronic diseases. The antioxidant capacity test measures the body's ability to suppress these reactive oxygen species, providing information necessary to understand the balance between reactive oxygen species and antioxidant capacity and maintain health.

What is the significance of the NK cell activity test?

The NK cell activity test measures the activity of NK cells, which are immune cells that destroy virus-infected cells or abnormal cells. If the activity is low, immunity decreases and the risk of disease increases, so this test can check potential immunity.
