DBS Congenital Hypothyroidism (TSH), 1 Mth

What is the DBS CAH 1 Month test?

This dried blood spot (DBS) test screens for congenital adrenal hyperplasia (CAH), a group of genetic disorders affecting adrenal hormone production in newborns.


Why is it done at 1 month?

Some forms of CAH may not be evident at birth. Testing at 1 month helps detect milder or delayed-onset cases to prevent complications.


How is the sample collected?

 A few drops of blood are taken from the baby's heel, dried on a special card, and sent for analysis.


What does an abnormal result mean?

It may suggest CAH and requires follow-up testing for confirmation, including hormone assays and genetic analysis.


Is early detection important?

Yes, early treatment with hormone replacement can prevent serious complications like salt-wasting crisis and support normal growth and development.
