Companies Offer Mail-Order Tests To Check For Signs Of Early Aging.

reports that several companies are offering mail-order tests that claim to measure signs of early aging.

However, some scientists say the tests fail to provide any medically-useful information. http://www.wsj.com/articles/mail-order-tests-check-cells-for-signs-of-early-aging-1477328529
