Raynaud's phenomenon

This is a test that measures the temperature of each finger after being submerged in an ice-water bath.

A heat sensor is taped to your fingers and the temperature is recorded. Your hand is then immersed in ice water for 20 seconds. Then it is removed from the bath and the temperature recorded every 5 minutes until your finger temperature is the same as it was before the bath.

No special preparation is necessary for this test.

For infants and children:

The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For specific information regarding how you can prepare your child, see the following topics:

• Infant test or procedure preparation (birth to 1 year)
• Toddler test or procedure preparation (1 to 3 years)
• Preschooler test or procedure preparation (3 to 6 years)
• Schoolage test or procedure preparation (6 to 12 years)
• Adolescent test or procedure preparation (12 to 18 years)

There may be some discomfort while your hand is in the cold water.

This test is a screening tool for Raynaud's phenomena.
