Benefits of Blood Test


Annual blood screening is the key component for preventing degenerative disease. By providing a comprehensive snapshot of your current state of health, blood screening can catch potential health problems in their early stages when they can be managed most effectively.

Sadly, many physicians request only minimal testing for their patients. As a result, many deadly diseases ranging from heart disease to cancer silently progress undetected until it is too late. Regular blood testing is the single most important tool available to prevent degenerative disease through early intervention. Many of the advanced tests offered by Life Extension are unavailable or unknown to many doctors. It is our goal to provide our members with the latest in blood screening so that they may better control their health.

Screening tests assess the status of numerous systems in the body, monitoring for cardiovascular risk factors, blood sugar levels, liver and kidney function, immune system wellness, and optimal hormone balance. Regular testing also monitors electrolyte levels, mineral balance, and red blood cell size and number.

Careful attention to your laboratory findings can help you reduce your risk for disorders such as heart disease, stroke, kidney disease, liver conditions, anemia, and diabetes. Regular testing also can help you prevent and treat conditions associated with hormone imbalances, including fatigue, erectile dysfunction, memory impairment, bone loss, weight gain, and depressed mood.

While many doctors routinely prescribe general tests such as total cholesterol, conventional medicine tends to neglect age-related hormone imbalances that develop in both men and women. The result is that many aging people suffer discomforts and diseases that are correctable and preventable by making simple hormone level adjustments. Mainstream medicine accepts these imbalances of life-sustaining hormones as “normal” in aging people. These practitioners almost never test for hormone levels, and largely reject the idea of restoring hormone profiles to youthful ranges. Increasingly, however, aging adults no longer want to be prisoners of poor health due to declining hormone levels.

Because most doctors rarely order advanced screening tests such as CRP (C-reactive protein), DHEA-S (dehydroepiandrosterone-sulfate) or estradiol, Life Extension created the Male and Female Life Extension Panels to provide a comprehensive overview of critical risk factors and predictors of future diseases. The panels comprise the most requested tests, which happen to be the best screening tools for identifying many common and not-so-common conditions. A yearly blood test is a relatively inexpensive investment when compared to the cost of disease-related health care and prescription medications, with tremendous potential to protect your health and increase your quality of life.

While many of the tests in the Male and Female Panels overlap, they diverge in measures that are specific to the health concerns of men or women. The men’s panel includes measurement of prostate-specific antigen (PSA), a marker of enlarged prostate or prostate cancer, while the women’s panel assesses progesterone levels, an important female hormone related to a host of menopausal and post-menopausal disorders.

Both panels include the CBC/Chemistry Profile, which measures over 40 different blood components, including cholesterol and triglyceride levels, blood glucose, iron and mineral levels, kidney and liver function, and blood cell components.

The Male and Female Panels also test for levels of total and free testosterone, DHEA-S (an indicator of adrenal cortical function), estradiol, homocysteine, and C-reactive protein (CRP). Both homocysteine and CRP, along with LDL, are powerful predictors of cardiovascular disease.
