No blood samples needed for the test
Mississippi State University Professor Ray Winton has reported in 2008 the development of a "smart bandage" that may completely do away with the need to use needles for testing cholesterol, insulin and blood chemistry. The bandage do not need a battery or other on-board power source, but picks it up by an antenna. After sensors detect specific information, the adhesive bandages can be read to indicate medical diagnostics.

  • You should not eat any thing before 12-14 hours of the blood sample is taken. Fasting before the test is required to get an accurate lipid level.
  • You should stop taking any medications like corticosteroids, estrogen or androgens, oral contraceptives, some diuretics, haloperidol, some antibiotics, and niacin.

The patient's blood is withdrawn by a syringe from one of the patient's veins in the arm. It takes only about five minutes.
