Researchers at startup Tasso, Inc. have developed a painless method for administering a blood test. The company created a device the size of a ping pong ball to painlessly draw blood without using a needle.

Instead of using the needle to break the skin and enter the vein, the disposable gadget uses a delicate vacuum to suction blood from your microscopic vessels called capillaries into an attached container. The process, which takes about two minutes, gently sucks up enough blood for routine tests such as measuring cholesterol.

The gadget is still in a trial phase, and Tasso is expected to submit the device to the FDA later this year. It recently received a $3 million grant from the DARPA. The company will use that money to research ways to create preservatives that stabilize the blood samples at 140 degrees Fahrenheit for up to a week so users can send it in at their own convenience.
