Guthrie Test

The Guthrie test is a blood screening method used to detect congenital hypothyroidism in newborns. It involves taking a small blood sample from the baby's heel and placing it on a special filter paper. The sample is then tested for elevated levels of certain substances, like thyroxine or related compounds, which indicate the possible presence of the condition. Early detection through this test allows for prompt treatment, preventing intellectual disability and growth problems. It is a simple, effective, and widely used screening tool to ensure newborns receive necessary care promptly.
