The Pronto can be used for adults and can be used with -children whose finger size is big enough to fit in the sensor, which is usually around age 2. Children with very small fingers or children who cannot sit still long enough to obtain a reading will need to be tested using a finger poke.

When it comes to finger size, you can use any finger for the test except the little finger\pinky. The finger must reach the end of the sensor, and the sensor should fit snugly. The finger should not slide around in the sensor. You may find that the thumb or middle finger is a better candidate for testing children. But if none of the child’s finders are large enough, you will need to do a finger poke, even if the child is older than two years old.

The Pronto test requires the participant to have their hands remain still while the readings are being taken. This can be challenging for small children! Later in this module, you will learn some strategies to help a child sit still long enough for the test to be completed.
