SUNDAY, June 15 (HealthDay News) -- The current standard screening test for prediabetes in children often fails to detect the condition, Canadian researchers contend.

FRIDAY, May 30 (HealthDay News) -- Better screening and diagnosis for diabetes is being called for to help the 6.2 million Americans who don't realize they have the disease, a new report says.

"Approximately 30 percent of people with diabetes in the United States are undiagnosed," study author Dr. Christopher Saudek, of Johns Hopkins School of Medicine in Baltimore, said in a prepared statement. "There are serious deficiencies in the current criteria for diagnosing diabetes, and these shortcomings are contributing to avoidable morbidity and mortality."
