Kansas Health Chemistry Screening


The Kansas Department of Health and Environmental Laboratories began testing forBlue Eyed Baby phenylketonuria (PKU) in 1965 when screening for neonatal PKU was mandated in Kansas. Over the next thirty years, the law was amended and the Health Chemistry laboratory added screening for congenital hypothyroidism (1977), galactosemia (1984), and hemoglobinopathies (1990).

On July 1, 2008, the Health Chemistry laboratory began the recommended expanded screening panel with the addition of screening for cystic fibrosis, biotinidase, and congenital adrenal hyperplasia. Additional screening for amino acid, fatty acid, and organic acid disorders were added on October 20, 2008, completing the expansion of the neonatal chemistry screening panel and increasing the number of disorders screened from 4 to a total of 29 as recommended by the national American College of Medical Genetics.

In Kansas, neonatal screening responsibilities are shared between the Health Chemistry laboratory and the Newborn Screening Follow-up Program of the Children's Developmental Services of the Kansas Department of Health and Environment. The Health Chemistry laboratory is responsible for the processing and testing of dried blood spot specimens, while the Newborn Screening Follow-up Program is responsible for notifying parents and doctors when there is an abnormal result. For further information visit the Newborn Screening Follow-up Program page.

A general explanation of Kansas Newborn Screening is found in the Kansas Department of Health and Environment brochures. For more information about our brochures designed for expectant or new mothers, please read the Kansas Newborn Screening Brochure or the Spanish version. If your facility would like a packet of brochures please fax your request to the Health Chemistry Screening Program at 785-296-0978. If you, as an expectant or new mother would like a brochure, please contact your obstetrician or general health care provider.

Specimen Guidelines

For all human specimens submitted for blood metals or newborn screening, see the Health Chemistry Specimen Submission Guidelines for specific collection, rejection, and transport guidelines.

Please see the Neonatal Chemistry page for detailed information on how to properly collect and ship a specimen.

On occasion, the laboratory receives specimens which are not satisfactory for newborn screening. These specimens will have a specific comment on the final laboratory report indicating the reason the specimen was not suitable for testing. For examples of unsatisfactory specimens, please view the Filter Paper Dried Blood Spot Unsatisfactory Codes document.

If your facility would like assistance on how to collect newborn screening dried blood spot filter paper specimens, the Newborn Metabolic Screening: Specimen Collection video may be helpful. If additional help or assistance is needed, please feel free to contact the Newborn Screening Follow-Up Program at 785-291-3363.
