Autism Detecting Tool M-CHAT/F Study: Children's Hospital of Philadelphia (CHOP) investigates the effectiveness of M-CHAT/F(Modified Checklist For Autism Toddlers with Follow-up) worldwide; CHOP found the M-CHAT/F Autism screening tool is less accurate when compared to the results of laboratory research. This study also revealed disparities involved in finding Autism in the minority, racial and low-income toddlers.
Be Aware of Autism Screening: The American Academy of Pediatrics (AAP) recommends toddlers of 18-24 months for ASD screening using M-CHAT/F, a two-stage parental survey to diagnose Autism affected children; AAP also follow-ups screened toddlers to reduce the rate of False positives.
Whitney Guthrie, Ph.D., a clinical psychologist specializing in early diagnosis at CHOP's Center for Autism Research explains that Early invention of Autism potentially helps adolescence; Accurate screening is the crucial step in the research and we know we are working on universal accuracy, she stresses.

What happened in Autism Spectrum M-CHAT/F screening? Electronic Health Record (EHR) of 25,999 patients has been studied by Children's Hospital of Philadelphia (CHOP) comprising 31 pediatric primary care centres. The primary care centres screened toddlers between the age of 16 and 26 months.
Autism Spectrum Screening continued using M-CHAT/F until 4 and 8 years old. Based on the screening, 91% of the children were screened Autism Spectrum by CHOP using M-CHAT/F; It covered almost all the children in the primary care sites.
Overall, 2.2% of children in the survey have diagnosed with Autism Spectrum compatible with Centers for Disease Control and Prevention (CDC) estimation. However, children who screened positive were diagnosed seven months earlier compared to children who screened negative. Thus helping early detection and medication of ASD affected children.
Failure leads to success: Pierce, Advocate of universal early screening for ASD, claims that screening provides more important lesson than perfection. Even though our study lacks screening clarities, reduction in the rate of screening by people increases the risk of detection and intervention.
The universal screening result forces us to reduce disparities by Pediatricians and implement an augmentative method of screening to diagnose more Autism affected children and engage in enriching their lives, Whitney Guthrie.
Racial Disparities: Pediatricians should focus only on screening children irrespective of racial and economic disparities to reveal better research ethics and norms. They also should be aware of diagnosing Autism and not the colour, language, economy of the children.
This Autism Screening Survey proves us how important the detection is irrespective of the failed screening.
