Routine blood tests are performed on your baby within the first few days of birth. Blood is drawn from your baby’s heel to measure blood glucose levels. As well, genetic screening is done for many rare and serious disorders such as hypothyroidism, galactosemia, phenylketonuria (PKU) and more.
Yes, the heel stick is somewhat painful for your newborn—just like for some adults who have their blood taken. Be there to cuddle and comfort your baby after the procedure. You may also ask to breastfeed your baby during the procedure or allow the baby to suck.
The number of tests for genetic screening varies, as required by law. As of September 8, 2005, the tests required in Ontario have now increased from the minimum of two (PKU and Hypothyroidism) to include testing for 21 rare genetic diseases. Blood for these tests is taken all at once. These tests are done so treatment can be started right away if it is needed.
