The first stage stratifies children into 3 group- low risk, medium risk, and high risk. Children who are medium risk go to the second stage for further clarification. A child whose score was greater than 3 at the first screening and greater than 2 on the second screening had a 47.5% risk of being diagnosed with autism spectrum disorder.
The Checklist for Autism in Toddlers (CHAT) is a psychological questionnaire designed to evaluate risk for autism spectrum disorder in children ages 18–24 months. The 14-question test is filled out by the parent and a pediatrician or physician and takes approximately 5 minutes to complete. [ 1 ]
Screening tools include the Modified Checklist for Autism in Toddlers (M-CHAT), the Early Screening of Autistic Traits Questionnaire, and the First Year Inventory; initial data on M-CHAT and its predecessor, the Checklist for Autism in Toddlers (CHAT), on children aged 18–30 months suggests that it is best used in a clinical setting and that ...
A methemoglobin level > 1.5 g/dL causes cyanosis. The most common congenital cause is a deficiency in the enzyme cytochrome b5 reductase which reduces methemoglobin in the blood. [22] However, in infants the most common cause of methemoglobinemia is acquired through the ingestion of nitrates (NO − 3) through well water or foods.
Methemoglobinemia, or methaemoglobinaemia, is a condition of elevated methemoglobin in the blood. [2] Symptoms may include headache, dizziness, shortness of breath ...
Parents of 1,150 primary school aged children were sent the CAST questionnaire, with 199 responders and 174 taking part in the full data analysis. The results suggested that, compared to other screening tools currently available, the CAST may be useful for identifying children at risk for autism spectrum disorders, in a mainstream non-clinical sample.
The psychologist evaluated 104 children, of whom 18 were judged to be delayed [14]). The Denver II yielded a high sensitivity rate, correctly identifying 83% of the previously noted delayed children. However, the screening test also identified more than half of the developmentally normal children as delayed, so its specificity (46%) was low.
The following disorders are additional conditions that may be detected by screening. Many are listed as "secondary targets" by the 2005 ACMG report. [1] Some states are now screening for more than 50 congenital conditions. Many of these are rare and unfamiliar to pediatricians and other primary health care professionals. [1] Blood cell disorders
