Newborn Dried Blood Spot Screening (NBS)

Introduction Neonatal Dry Blood Spot Screening (NBS) is the most widely used screening technique to identify infants with specific hereditary, metabolic and endocrine disorders. Take a few drops of blood from the heel of the baby and place it on the filter card. Many countries are considering expanding their new birth thrombosis screening program. As a public health intervention, the National Bureau of Statistics greatly improved the lives of thousands of affected children. However, the newborn screening saved the lives of thousands of children and helped more children avoid permanent obstacles, but previous experiences showed that screening is expensive and leads to a psychological barrier I showed it.

Most people are listening to newborn screening Most people imagine that the baby 's feet sticks to the lancet soon and the blood is collected on dry cards. Soon after, their baby doctor told them, "Everything is okay." Or they may not have any clue at all. More and more newborns may cause congenital metabolic abnormalities early in life. Urea circuit abnormalities, organic acidemias and amino acid metabolism have various symptoms including lethargy, rejection or poor feeding as well as various symptoms of acute or chronic encephalopathy. Tachycardia, shortness of breath, even even apnea, may be prominent signs. Myobody pneumococcal deficiency with nonketonic hyperglycemia, severe metabolic acidosis may be the first symptom of a newborn with a disease

Let's fast forward towards the 2000s when screening newborn babies effectively and obtaining more genetic conditions than PKU. Indeed, we can test dry spots of blood with hundreds of genetic conditions. What is the genetic condition for your baby to be screened as a newborn? Interestingly, that is the date on which your baby was born and on the first day after birth, the baby is officially handed over (if you are in the United States). Due to deciding to add conditions to newborn screening in each state, the number of genetic conditions examined at each newborn's dry blood spot varies from state to state. Currently, the number of diseases in each state range from 39 to over 50 genetic conditions. This means that if you have a child in Utah last year, because you live in New York, newborns will be screened under various conditions.

Studies have shown that affected newborns are rarely discovered during the first few months of life and are often overlooked before 1 to 3 years of age. Congenital hypothyroidism is an ideal candidate for the introduction of dry-blood neonatal screening in Dussault, Canada. A newborn screening program was developed in many parts of the world with the development of a sensitive assay that measures thyroid hormone (T4) and thyroid stimulating hormone (TSH) using dried blood spots (DBS). In the 1980s, the incidence of CH in the United States was estimated to be 1: 3000 - 1: 4000. Recently, the incidence of screening programs has reported an increase of 1: 1400-1: 2800. This is most likely due to screening strategy changes and minor case identification.
