LOX-index® Test for Stroke & Heart Attack Risk

LOX-index® Test: Future Stroke & Heart Attack Risk Assessment

Are you concerned about your future health, even with normal check-up results? Hamada Hospital offers the LOX-index® test, a simple blood test to evaluate your future risk of developing a cerebral infarction (stroke) or myocardial infarction (heart attack). By understanding your risk for arteriosclerosis (hardening of the arteries) before symptoms appear, you can take proactive steps to improve your lifestyle and protect your long-term health. This test can be taken on its own or as an option with a comprehensive health check-up. The fee is ¥13,200 (tax included).

Who Should Consider the LOX-index® Test?

• Individuals with a family history of stroke or heart attack.
• Those diagnosed with or at risk for high blood pressure, dyslipidemia, or diabetes.
• Anyone aged 40 or over.
• Individuals who are overweight, concerned about metabolic syndrome, or have a history of smoking.

How the LOX-index® Test Works

• Measures two key substances directly involved in the early stages of arteriosclerosis: modified LDL (oxidized bad cholesterol) and the LOX-1 receptor.
• The test involves a simple blood draw (approx. 4ml) with no fasting required.
• Provides a comprehensive risk assessment for the next 10 years based on scientific data from a large-scale Japanese study.
• You will receive a detailed, easy-to-understand report by mail in about 3 weeks, including personalized lifestyle advice.

Frequently Asked Questions

Q. Is there an age limit for taking the test?

A. There is no specific age limit, but we particularly recommend it for people aged 40 and over, when the risk of arteriosclerosis begins to rise. Of course, younger people concerned about an unhealthy lifestyle, or those who want to understand their health condition early, are also welcome to take it.

Q. How is it different from the blood test in a regular health check-up?

A. A general health check-up blood test mainly measures values such as LDL (bad) cholesterol and triglycerides, but these are “indirect” indicators of arteriosclerosis. The LOX-index® test measures “denatured LDL” and “LOX-1,” which are directly involved in the early stages of arteriosclerosis. The major difference is that it can assess the condition of your blood vessels earlier and more directly.

Q. Do I need to skip a meal on the day of the test?

A. The LOX-index® test is not easily affected by food, so no dietary restrictions are required. You can come in as you normally would.
