Tests for congenital metabolic disorders, etc.

　In Yokohama City, we participated in a national demonstration project, and from October 1, 2024, expanded newborn mass screening tests will be conducted at public expense for two diseases, severe complex immunodeficiency (SCID) and spinal muscular atrophy (SMA).

・Severe compound immunodeficiency (SCID):
　It is a life-threatening disease in which immune cells do not work well and the resistance to infection decreases. In addition, live vaccination is contraindicated, and it may not be possible to identify it in an interview up to two months after birth at the time of vaccination.
・Spinal muscular atrophy (SMA):
　It is a progressive disease in which the muscles of the whole body are reduced due to genes.
　　
　With regard to these two diseases, advances in treatment technology and the development of therapeutic drugs have progressed in recent years, and early detection and early treatment are expected to prevent symptom improvement and seriousness.

It is treated in the same way as conventional tests for 20 diseases. Please check here for details.
　

　In order to verify the effectiveness of neonatal mass screening tests for SCID and SMA, children who have been tested will be given due consideration to the protection of personal information for newborn mass screening tests, the number of positive persons, and the results of detailed examinations ( Disease name and number of patients) are reported to the research groups of the Children's Home Agency and Children's Home Agency.
　The information obtained in this demonstration project will not be used for any other purpose. In addition, when the results of research are published, they will be statistically processed and will not be published in a way that identifies individuals.
　

・Newborn mass screening tests do not find all severe complex immunodeficiency or spinal muscular atrophy.
・In addition to severe complex immunodeficiency and spinal muscular atrophy, diseases that cause immunodeficiency may be found.
・This test is a screening test. Even if a detailed examination is deemed necessary, the results of a detailed examination may be diagnosed as "no illness."
・Applicable from the blood collection on October 1, 2024. Please ask a medical institution about the implementation.
・In order to carry out the demonstration project integrally with the conventional 20 diseases, those who have undergone a test (test for 20 diseases) such as congenital metabolic abnormalities at other prefectural medical institutions on their way home are not eligible.

　This is a test to detect diseases of congenital metabolic abnormalities. It is performed at hospitals that are hospitalized for childbirth, and blood is taken from the soles of the baby's feet to check it.
　Babies with congenital metabolic disorders, etc., may look completely healthy at birth, but if left unchecked, may cause physical or intellectual disabilities, or may be at risk of life.
　However, these diseases can be detected early, and if appropriate treatment is continued, the occurrence of disabilities can be prevented.
