Unless restricted by local regulations, in most states in the U.S. and in many other locales, it is possible to order one's own lab work.
Life Extension Foundation (www.lef.org) has for many years promoted the practice of individuals monitoring their health through regular blood testing by offering lab work at steeply discounted costs to members and having annual blood test sales with even lower prices. Recently, they have allowed membership to be paid with a small amount monthly.
In recent years, many other online sites have become available where blood tests can be purchased at discounted costs.
These sites provide orders by a physician for blood tests at a laboratory local to the purchaser. A LabCorp facility is most commonly used, unless one is not available in the area. Results are emailed, faxed or mailed and are usually available within one or two days for most tests.
Pricing varies among online services, so it is a good idea to check the total cost from three or four for the tests that you are seeking. Different companies may also offer various tests grouped in panels for better pricing.
