Early detection examinations for children - from U1 to J1

The early detection of diseases is an integral part of medicine – especially in paediatrics. Therefore, parents should use the examinations for the early detection of diseases, which all children are entitled to in the statutory health insurance. The examinations should be mandatory appointments of parental care. After the birth of a child, the parents receive a yellow examination booklet. All early detection examinations are recorded in this booklet, so it should always be kept safe. The early detection examinations are abbreviated to U1 to U9. There is also a so-called J-examination for young people.

What are the investigations for?

The physical, mental and social development is checked with the examinations. In this way, the child’s development or possible undesirable developments can be recorded, and – if necessary – appropriate therapy can be initiated.

The examinations are, therefore, an essential building block to protect the health of our children.
